Q&A

Resolution: Sony A7RII vs. Leica SL vs. Nikon D810 vs. Canon 5DS R.

Inspiration, Q&A, Reader Smackdown, Teaching point

I’ve always found DPREVIEW‘s studio comparison tool useful when evaluating cameras for resolution.

Here is the entire scene (I’ve added the numbers with red circles):

Now here is the comparison I ran with four cameras of interest (using RAW files).

I specifically focused on the numbered areas above.

Let me know what you think…

This image was taken at the same time as all of my other recently posted images, before I realized that my 58/1.4 lens was front-focusing.

The intended focus here was the near eye, but the actual focus ended up being on the front of the hat.

Still, I like this image.

Nikon, Pentax, Sony.

Nikon, Pentax, Sony

I had an opportunity to handle a Nikon D810, a Pentax 645Z, and a Sony A7RII yesterday.

Previously, I’ve owned a D800E, a 645D, and an A7s, so I was familiar — in a general sense — with each manufacturer’s offerings.

Ultimately, I had abandoned all of those last generation models, for one reason or another.

Care to guess which one of the latest generation offerings I found the most desirable?  The least?

Burning a hole.

Prosophos - Burning a Shutter Curtain Hole

Yes, I did it.

I managed to burn a hole in my M3 shutter curtain.

After all of these years… this is a first.  I had read about it but never really worried about it.

As far as I can tell, it was caused by not having the lens cap on while I was outside in intense sunlight (at the Blue Jays game).  My uncapped lens likely focused the rays of light onto a small area of the shutter cloth and — voila! — a hole was created.

This is what the hole was doing to all of my film images:

Fortunately the curtain can be easily repaired/patched.

Now I have to reconsider my w(hole) modus operandi for shooting.  I have been using my lenses with protective hoods and filters but no lens caps.

Undisclosed Lens #3 (test shot on digital).

Inspiration, Leica M9(P)/M-E (CCD Lives!), Q&A, Teaching point, Undisclosed Lens #3

If you have been following along, my last few posts contain photographs created with Undisclosed Lens #3.

So far, I’ve only shot with it on film.

I decided to examine central sharpness, wide open, on the Leica M9.

Here is the original test shot:

And here is the central crop of the above image, at 100%:

Once again, I’m quite impressed with this lens.
