Just the MTF Charts: 70-200mm f/4 Zoom Lenses
We did the 70-200mm f/2.8 lens MTF charts last week, so let’s do the f/4 versions of the same range now. Sports shooters and portrait photographers need that f/2.8 aperture, but many of us, most of the time, are willing to trade that off for smaller-lighter-less expensive f/4 models. ### So, About…

Just the MTF Charts: 70-200mm f2.8 Zoom Lenses
Well, I’ve avoided putting up the zoom lenses as long as I could, but here we are. I’m going to do things a little differently; rather than listing by brand I’m going to try listing by range and type. I’m suspicious of it because it’s going to bring out the Brand Zealots who for some reason find…

Just the Cinema Lens MTF Charts: Xeen and Schneider
We’ve completed the MTF postings for all of the photo prime lenses. Now we’re going to start with the Cinema primes. For a lot of those that also have a photo version, the optics should be identical. That’s not always the case, however. Plus, the people interested in Cinema lenses aren’t usually…

Just MTF Charts: Perspective Control Lenses
I had a little hesitation about whether we should post these. Most people considering a tilt-shift aren’t thinking ‘I want the absolute best sharpness.” Plus what we show is the MTF without the lens tilted or shifted, both of which will affect the resolution to some degree, but you’re probably…

Just MTF Charts: Rokinon / Samyang Lenses
I’m going to add some qualifications to the Rokinon / Samyang MTF post. First, the results are a mixture of both brands (which are identical except for the label). Lensrentals stocks mostly Rokinon labeled because of better (the bar is low here) service in the U.S., so the website calls them…

Just MTF Charts: Nikon Prime Lenses
We’ll continue our just MTF chart series of posts with the Nikon brand prime lenses. For those of you who have been asking, The Digital Picture is going to add all our MTF graphs to their comparison tool as we release them. That will let you do logical comparisons like ‘is the Sony 135mm f/1.8 GM…

Just MTF Charts: Sony FE Mount Prime Lenses
This is the fourth post publishing all of our MTF results so that methodology is consistent and they are easy to find. The previous have been by lens brand. This one is by the mount, since the Zeiss Batis and Loxia lenses fit more naturally here than with the Zeiss SLR lenses. Otherwise, no…

Just MTF Charts: Sigma Prime Lenses
This is the third post publishing all of our MTF results so that methodology is consistent and they are easy to find. No comparisons, no commentary, just the test results for you to use and abuse as you see fit. We’ll continue today with the Sigma prime lenses. For those who wonder, the results…

Just MTF Charts: Zeiss SLR Lenses
_Please note: The Zeiss Batis and Loxia Lenses will be presented with the Sony FE mount prime lenses._ Over the last 5 or 6 years we’ve run more MTF tests than anyone in the world. We do a lot of stuff with those results, but the one thing that’s pertinent is we publish them on our blog posts. I…

Just MTF Charts: Canon Prime Lenses
This is the first post of a series of posts publishing all of our MTF results so that methodology is consistent, easy to find, and up-to-date. (For some of the older lenses there are graphs done with older software floating around. For a couple of lenses there are incorrect graphs done before we…

Sony FE 135mm f1.8 GM Early MTF Results
As is sometimes the case, I got access to a couple of pre-release copies of the new Sony FE 135mm f1.8 GM lens. Of course, if I get access, it gets MTF bench tested. I mounted the first one, sipped my coffee and then lost my mind and started shouting various expletives, enough to bring Aaron…
