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 MTF Charts: Tokina and Veydra Primes
The Zeiss post was really long, this one is pretty short. I will mention again, these are less than 10 copy averages; we don’t carry a lot of these lenses. But there’s no MTF data elsewhere for them, so I will put out what we have. A Quick How to on Reading MTF Charts If you’re new here, you’ll see…
Just the Cinema MTF Charts: Zeiss Cine Lenses
Zeiss makes a lot of cinema lenses, there are a lot of graphs in this post. Please remember for some, like the Supreme Primes and some of the CP.3 lenses we didn’t get much access to, the MTF graph is the average of just a few copies (the number of copies is identified on the graph). This will be…
Just the Cinema Lens MTF Charts: Canon and Sigma
We’re going to continue the Cinema prime MTFs with the Canon and Sigma lenses. Again, we’re not going in any particular order, other than what we have handy and what fits reasonably into a single post. Since these are among our most popular cinema lenses, we do generally have at least a 10-copy set…
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 the MTF Charts: Micro 4/3 Lenses
Not a lot to say specifically about the m4/3 lenses except please don’t ask why your favorite isn’t on here; this is all I’ve got. Some of the newer m4/3 have linear electronic focusing which can’t be tested on the bench without a specialized, expensive mount and we don’t have one. Even for the…
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…
