SALT III: a Comprehensive and Thorough High-Speed Professional Lens Shootout
There are now more options than ever for good professionally built lenses, and many of them are exceptionally fast. None of them are perfect at their widest aperture (well, a few come as close as possible), but there are times when you just need that extra stop or two of light, even if you might normally be shooting more closed down. SALT, the Southland Alternative Lens Test, is conducted by a group of professionals who test a wide range of lenses against each other in difficult situations, trying to determine the strengths and weaknesses of each set of lenses. The most recent test, WFO, is specifically designed to push lenses like Master Primes, Zeiss Super Speeds, and Canon Cine lenses at their widest aperture to see how well they perform. Check out the test below.
A little bit more about the test, from Matt Hayslett's blog:
The purpose of this shootout was to directly compare lens sets on an identical setup. Our goal was not to “test” the lenses, rather provide you with all the info necessary to evaluate the lenses and decide what works for you. These lenses cover a wide range in affordability and availability. This shootout was never meant to prove which set is better than the other. We hope you will see that any of these lenses could be used to shoot quality material and have been for years. We attempted to get Cooke 5i’s for the test but unfortunately none were available at the time. Some of the lenses have slightly varying focal lengths so understand field of view may appear slightly different (i.e. 24mm vs 25mm, 75mm vs. 85mm). Please also keep in mind the slight differences in exposure since we were working with lenses rated between T 1.3 and T 1.5. No matte box was used to ensure there was no vignetting or concealing of flares.
We all know these lenses perform well closed down to a T 2.8, so this shootout was designed to push the lenses to their limits wide open. Most of the flaws visible wide open disappear once stopped down (examples will be available for download).
Watch the entire test below. It runs around 45 minutes, but there are actually more lenses thrown in than just the ones listed above, so it's interesting to see the others compared as well. If you'd like to download a 2K or 4K file of the video, you can find them here:
These are the results from the lens projector, which show the resolution and characteristics of the lenses:

The great thing about these options is that all of them have their own specific looks. Knowing the limits of a lens will allow you to utilize it to the best of its abilities. While all of these lenses were tested on the EPIC, I actually think I've seen some of the best looking projects shot on lenses that weren't as sharp and actually experienced a bit of chromatic aberration. Just because a lens is technically perfect doesn't mean you will necessarily like the look, which is one of the reasons that lens performance is about more than just specifications.
It's pretty obvious why the Master Primes get so much usage on higher-end shoots, especially since they are about as perfect as a lens can be wide open. Be sure to head on over to Duclos' and Hayslett's respective sites for more in-depth information about the test, and for the full R3D, JPEGs, and lens projector results.
What do you guys think? Which was your favorite? Did any of them surprise you?
