The Leica M11.

The Leica M11 will have >40 MP.

That will really reveal focus errors when using fast lenses wide open.  Technique will therefore matter more than ever.

It would be nice if the new sensor achieves greater dynamic range and colour accuracy (which admittedly is already quite good with what we have).

Leica, please just keep the optical viewfinder (that’s a personal request).


Coffee Break.

This image is in follow-up to the discussion here.


Fujifilm GFX 50R + Fujifilm 63mm f/2.8 R WR.

7Artisans 50mm f/1.1 (cropped image).

I’ve been getting a lot of questions about wide open performance of the The 7Artisans 50mm f/1.1 (Leica M mount), since revealing that it is my Undisclosed Lens #7.

So, I thought I would show another example image, followed by a central crop.

The last time I did this was when I was comparing this lens to the Leica 50mm Summilux ASPH.  Despite making that comparison, I don’t believe there is any value in such head-to-head tests when considering this lens, because it is not an optic that one purchases for checklist attributes.  Instead, the 7Artisans 50/1.1 should be regarded much like the Leica Noctilux f.1 and the Zeiss Sonnar f/1.5 lenses, which are coveted for their artistic rendering.

Having said that, the 50/1.1 is often mistakenly labelled as “soft” when used at f/1.1.  Though it is not razor sharp wide open (and can be “glowy” at near distance — see the aforementioned comparison), it is certainly sharp enough for me.  I would, in fact, caution anyone who believes that this lens is “soft” at f/1.1 to make sure they have calibrated it correctly (or are practicing good technique).

Case in point, here is another image taken at the time of the Night Light photo I recently posted, photographed  at f/1.1:

Leica M10 + 7Artisans 50mm f/1.1.

Now, here is the magnified central portion of the frame (focus is on the eyelashes of the near eye):

I will let you decide if it is sharp enough for you and whether — in the case of an f/1.1 lens — it really matters.


My Leica M10 Lightroom Presets.

I recently discussed the Lightroom Presets I have been working on, and a few of you asked whether they could be purchased.

My initial response was no, for the simple reason that it is time-consuming to provide technical support for any issues that may arise.  However, I continue to receive requests and responding to each one has — ironically — consumed a good chunk of time! 🙂

So here’s what I’ve decided to do:

I will make my 3 presets available for purchase but with the understanding that:

  1. There will be no technical support (you assume the burden of installing/using these!).  I will, however, say this much about their intended use: the “Film Base” preset is meant for photos that are exposed properly or slightly over-exposed; the “Film Soft Portrait” preset is meant for photos that are slightly underexposed or, as its name suggests, for portraits; the “Skin Tones” preset reduces red/orange contamination in skin tones.
  2. The presets are not meant to yield “finished” images.  For some photos they may be sufficient, but for most they will only serve as a good starting point.  Essentially, these presets contain the settings I use when I begin post-processing my Leica M10 files.  They are not meant to emulate a specific film; I am not interested in re-inventing a look that was perfected by Kodak, Fuji, etc.  If you want the look of film, I suggest you photograph with it!  The only reason the word “film” appears in the names is because of how I’ve set the tone curve to handle light and shadows (the way most films do).

If you agree to the above, my three Leica M10 presets may be purchased for:

US $15

(total price for all 3)

Are they are worth $15?   I’ll leave it up to you to decide.  They help me save time and effort, so they are certainly valuable to me.

If you are still interested in proceeding:

Click here to purchase via PayPal.

Once payment is received, the files will be sent to you via email and you will need to import them into your copy of Lightroom.

Please note that it may take up to 24 hours for me to email you the presets.






The identity of Undisclosed Lens #7.

Undisclosed Lens #7 is:

The 7Artisans 50mm f/1.1 (Leica M mount)

The comparison test I posted yesterday revealed something unexpected: the minimum focus distance is greater than the advertised 0.7 m (either that or my Leica 50mm Summilux ASPH focuses closer than 0.7 m, which is unlikely).  I hadn’t noticed it until I ran the head-to-head comparison and found that I couldn’t get as close with the 7Artisans as I could with the Leica.

Other than that (disappointing) surprise, I have been satisfied with the 7Artisans 50mm f/1.1.  It’s an interesting lens that has polarized photographers’ opinions of it (although some have passed judgment without actually laying their hands on one).   The mini-controversy surrounding it was the main reason I wanted to post images without first identifying the lens.

Those who criticize this 7Artisans lens I think miss the point.  In my case, I bought it hoping for a dreamy look (for lack of a better phrase) that the technically more capable 50 ‘lux does not as readily provide.

Moreover, having previously owned the Leica f/1 Noctilux (a lens also known for its dreamy look), I would say that the 7Artisans 50mm f/1.1 compares quite favourably and it would, in fact, be my choice between the two.


Examples of recent images:





Test: Leica 50mm Summilux vs. Undisclosed Lens #7.

Leica 50mm Summilux ASPH vs. Undisclosed Lens #7.

(EDIT January 4, 2018 I have revealed the identify of Lens #7 here.)

  • Both lenses mounted on a Leica M10
  • @ f/1.4
  • @ minimum 0.7 m focus distance (nonetheless, notice the field of view difference)
  • Identical default sharpening settings in Lightroom
  • No post-processing (nonetheless, notice colour differences)


Entire scene (please click on image to enlarge):

100% centre crop (please click on image to enlarge):

Which one is “superior”?:

Clearly the Leica 50mm Summilux ASPH.

Will I still continue to use Undisclosed Lens #7?:

Yes.  I value this lens for its “flaws”.


Film Photographers Rejoice! New Plustek OpticFilm 120 Pro Film Scanner.

I’m sure a few of you already know this, but for those of you who don’t, Plustek is introducing an updated version of its OpticFilm 120 film scanner.  The new scanner is called the Plustek OpticFilm 120 Pro.

I asked for an improved version of the 120 a year-and-a-half ago and it looks like Plustek has come through.

Having owned several Plustek dedicated film scanners, I can say that I have been satisfied with their products (and consider them superior to flatbed scanners) but would of course welcome improvements in ease of use, precision, speed, resolution, and dynamic range.

Therefore, I am really looking forward to seeing this new scanner in action.



Praying for time.

Test Shot #4, a candid portrait, created with Undisclosed Lens #7.

Maybe we should all be praying for time.


Leica M10 + Undisclosed Lens #7.

Oh the irony.

Today I finally figured out how to properly process my Leica M10 files (the irony is that last weekend I announced the end of this blog).

After months of experimentation, I created a custom preset in Lightroom that strikes a nice balance between punching up the contrast and colour, enhancing skin tones, and preserving detail.  The overall effect is subtle, which is what I want.

Most of the commercial presets I’ve tried result in cartoonish effects (specifically, with respect to colour shifts and detail obliteration) that are painted over with digital “grain”, so I’ve avoided using them.

Here is an example of my preset in action:

Here is another example:

I can’t wait to work with this (and possibly fine-tune it some more).

By the way, I want to thank all of you who took the time to write to me, both on this site and via email, with words of encouragement.  I am very grateful for your kindness.


Follow-up to last week’s post: The Leica 50mm Summilux ASPH Black Chrome (Special Edition).

Last week I questioned whether the production run of the Leica 50mm Summilux ASPH Matte Black Chrome lens was limited to only 500 units, given the continued availability of this lens (brand new) several years after its introduction.

George, one of the participants in that discussion, wrote to me today with some follow-up commentary I thought was worth sharing (with his permission):

Peter, here is what I found out through Steve Huff’s and Thorsten Overgaard’s sites and the Leica Store in SoHo—all of which is very confusing.  I sent this post to Steve Huff for comment thinking that he might have some insights and have been waiting.  But I haven’t heard from Steve, so I thought I would post it on your site, and if I hear from Steve, I will let you know.

In January, 2016  Ken Hansen sent Steve Huff the LHSA black chrome limited special edition 50 mm Lux lens, of which there were 500, to review.   On his website, Steve mentioned that he bought this same lens for $3600 in the M8 days when it was in black paint and also a LHSA limited special edition.  He said he sold the lens for $8,000.  Thorsten Overgaard in reviewing the 50 mm Lux black chrome limited special edition lens on his website also mentioned the earlier version black paint limited edition and its appreciation from $3600 to $8,000 as a good reason for him to hold on to his black chrome limited special edition.  Clearly both Steve and Thorsten believed that only 500 of the black chrome 50 mm Lux limited edition lens were produced and that it would similarly appreciate.   Interestingly enough, Steve mentioned that the only identification of the 50 mm Lux black chrome lens as a limited edition was the Leica Historical Society (LHS) name on the box.   And he mentioned that Ken Hansen had a few lenses remaining, but B&H was also selling them.  However, said Steve, “there were only a few available [remaining] in the world.”

Now when I bought my lens from B&H shortly after Steve received his lens (in fact, I learned about the lens on Steve’s website), there wasn’t the LHS name on my box, which makes me wonder if there were two productions of this lens at the same time—the LHSA so called limited edition as well as another production not associated with LHSA.  It seems the only thing that made this lens a limited edition is its association with the Leica Historical Society of America (LHSA that amounted to simply a name on 500 boxes.  

Nevertheless, B&H continues to this day to use the original LHSA limited edition advertising for all black chrome 50 mm special edition lenses for sale since essentially it is the same identical lens albeit for the LHS name on the box, which is really false advertising by B&H although you can understand why they might be confused.

Leica SoHo said that they believe that Leica produced another 500 lenses (who knows when) after I purchased my lens but will not know for sure until they see production numbers.   When such production numbers will be available, they don’t know. The SoHo store has two of the lenses for sale and is not selling them as limited edition lenses.  I don’t know how many B&H has, but they do state in their description that it is a limited edition of 500.

Therefore, it appears to me that the problem is with B&H and Leica.  While Leica apparently continues to produce and sell this lens, B&H continues to use the advertising associated with the LHSA limited edition of the lens.  It seems (again who knows for sure) that Leica has not been clear with its customers that this lens was not in fact going to be limited to 500 produced and that the only thing making it limited is the LHS name on a box.  Also, it seems to have even fooled Steve Huff and Thorsten Overgaad.  In fact, Overgaard doesn’t even mention LHSA but simply describes the lens as a limited edition.  If this lens is truly not limited in production like the black paint edition that Steve Huff owned in his M8 days, I don’t see how it could possibly experience a similar appreciation.  I didn’t purchase the lens as an investment, but I did think that I had purchased a “limited edition,” which it appears I don’t have.  In fact, my box doesn’t even say Black Chrome Special Edition on it, although it has the correct serial number.

Nevertheless, here is what Leica said about this Special Edition lens, which B&H includes in its advertising: “As part of a limited edition of 500 pieces, this black-chrome finish Summilux-M 50mm f/1.4 ASPH lens features a matte black exterior as well as an outer design that resembles the first edition of this lens from 1959.”  Are “pieces” boxes or lenses?


Borrowing from the famous movie, Cool Hand Luke, “what we [may] have here is a [serious if not egregious] failure to communicate.”

The problem with digital photo archiving.

The New York Times published an article this week, discussing the practical difficulties with long-term storage and tracking of all of the digital photos we create:

This is an issue I’m sure we’ve all thought about.

My working solution has been to store cherished photos on two back-up external drives, one that saves them in real-time and another that I use for a yearly back-up (but that remains in a safe the rest of the year).   I also have many images uploaded to a cloud-based storage service.

I’m not saying this method is the best, or even good, but for me it’s the solution that best balances a sense of (false?) security with practical considerations.

In contrast to many individuals, I tend to avoid taking photos with my iPhone because, although they too are uploaded automatically to Apple’s servers (i.e. the Cloud), I don’t often make back-up copies on my external drives, so I feel less in control of them.  Also, I prefer photographing with a dedicated camera anyway.

A few years ago, I read an article in The Telegraph where a top-tier Google executive predicted that all of our digital photos will likely be wiped out, if we don’t figure out a better way to preserve them.

Thinking about that further, I guess the best thing I’ve done to preserve our family’s images was to create photo books which were distributed, annually, to family members.  The problem with this is that it’s very time-consuming and expensive (especially when you are making half a dozen copies of each book).  Hence the last time I did it was in 2014.

Nonetheless, I guess I better start making books again… maybe next year.

Addendum:  I almost forgot — the other thing I’ve done is to intermittently photograph with the anti-digital medium: film.


Leica 50mm f/1.4 Summilux ASPH Matte Black Chrome (Special Edition).

Okay, I’m going to go out on a limb here… again 😉

Leica claims that the production run of the 50mm Summilux ASPH Matte Black Chrome lens was limited to only 500 units.

That can’t be true.

This special edition 50 ‘Lux was first released years ago and for many months later you could still find brand new ones for sale.   Since then, they have gone in-and-out-of-stock several times.   New ones are (as of today) still available for purchase — some at a discount.

Limited to 500?   Really?


The Leica 50mm Summilux ASPH f/1.4 (Micro-) Review.

This is the one lens I always come back to, whenever I foolishly part with it for the latest and greatest.

If ever write a full review about the Leica 50mm Summilux ASPH f/1.4, I will include the table below, which I put together using data from

If there is another 50mm lens out there that better balances performance, speed, size, build quality — and even price — I haven’t seen it.

Sisters (1 and 2).

I really love seeing them like this… enjoying each other’s company.

On a completely different (and technical) note, these images were not post-processed in any way.  I had nothing to add to what the M10 produced.  First time I can recall that happening to me with any digital camera.


Leica M10 + Leica 50mm Summilux ASPH f/1.4.

Leica M10-D Rumour and Aaron C. Greenman’s Post from 4.5 years ago.

According to Leica Rumors, the Leica M10-D will be arriving shortly.

Looking back to a Guest Post by Aaron C. Greenman almost 5 years ago, it seems that many of the items on his wish list have been incorporated into the new model.

I can’t wait to see if his request for a lever that manually re-cocks the shutter has been included, as the “leaked” images seem to suggest.

No CCD sensor though, so in that sense we are probably both disappointed 🙂


Photography has always been furthered by technology, but…

It’s true:  photography has always been furthered by technology.

What I mean is that, as technology has advanced (first during the film era, and now digital), photographers have increasingly been provided with the tools to more easily record/convey their vision.

However, I’m not so sure that the last 5 years have given us anything along the same vein.



Leica M2-R (Test Images).

Yesterday, I posted some images of the Leica M2-R I was fortunate to acquire.  The photos were taken with a Leica M10 and processed in Lightroom with relative ease.

In contrast, today I set upon the boring and arduous task of testing the M2-R without — of course — the immediate feedback of digital photography.  As I subsequently stood in my basement processing the film, I must admit that I had second thoughts about whether all of the hassle was worth it.  It’s especially frustrating when the effort of processing and scanning is undertaken only to find out that the camera is in some way defective.

Fortunately in this case, all is good.

And as I watched the images magically appear — first on the negative as it was unspooled following its final wash, and then in more detail on my monitor as the scanner did its thing — I realized for the 1000th time why I keep coming back to film: even mundane test shots look better on this antiquated “sensor”.

The following images are not meant to be interesting.  However, they are useful to me.  In them, I’m verifying:

  1. Shutter speed accuracy (in various types of light)
  2. Rangefinder precision (in near, mid, and far distances)


  • Lens: Leica 50mm Summilux
  • Aperture: f/1.4 (except the last image which, because of brightness, necessitated f/2).
  • Shutter speed range: 1/60 – 1/1000 sec.

Leica M2-R + Leica 50mm Summilux ASPH f/1.4.

I stopped using Instagram a year ago.

A year ago, I deleted my Prosophos Instagram account.

I can tell you why I did it, but I wasn’t planning to in this post.  Suffice it to say, I think social media in general is a vex on all of us, and Instagram in particular is a vex on photography.  Funny enough, I still keep a Twitter account active, but all it does is link back to posts on this site.

In order to protect my “online identity” from people up to no good, I subsequently reserved the name @PhotographsbyPeter.  The Prosophos account was no longer active (once deleted, Instagram does not allow you to re-claim it).  However, recently I realized that @prosophos (with the lowercase “p”) is considered a unique name, so I claimed that one too.

Both of those IG accounts have a placeholder composite photo attached to them, but that’s all they will ever have.
