Sigma 50mm T1.5 FF High-Speed Prime (Sony E-Mount, Feet)

Pleasantly surprised by this lens. Used to own Zeiss CP.2, and have rented the CP.2 Super Speed 50mm many times, as well as the Canon CN-E lenses. In terms of sharpness, this Sigma easily beats all three of those. In some ways, this is to be expected because those are older lenses, and were designed before 4K was a ubiquitous resolution. If you're still shooting/delivering in HD, then it may not matter. These days, the differences are noticeable in 4k, especially shooting wider than T4. This lens is an amazing value and punches well above her weight. Sharp enough to resolve tack-sharp in 4k, and they claim it's sharp enough for 8k. I won't comment much on color/contrast rendition and character because it's so subjective, but to me it produces a very straightforward and grade-able look and doesn't seem to color the footage much. Also haven't tested/can't comment on lens flare characteristics. Favorite features: -Hardly any chromatic aberration wide open, which is where the other lenses in this range typically fall apart wider than T4. Still very sharp at T2. -Offered in E-Mount with is great for my FS7. -Build quality is as good as one would hope for a lens in this range. -No focus breathing!
