  1. Nice review…thank you. I own 2 Sigma 135s (for my Nikon D4/D700/D500 and Canon 5D Mk IV) and I've no complaints (rich colors, no focus issues, sharp), however, I'm considering the Sony A7RIV and I may buy the GM135. Sony Tech advised any Sony Full Frame lens will resolve 100% detail on the 61MP sensor, but DP Rvw, Jul 2017, stated "…Sony developed the GM Lenses to support 50-100MP sensors." Very confusing.

  2. What do you think about the 135mm focal length for concert and sports photography? I was debating getting the Sigma 135mm or the Sony 70-200mm f4 for my A7iii.

  3. I have had the sigma since it came out. While there maybe some better lenses …. the sigma is so good that I just don't care what others shoot with … the sigma is a gem.

  4. I just purchased the Sigma 135mm f/1.8 for my X-T3's (I have four of them now 🤩) and the Fringer Pro ll adapter (EF to FX) Effectively a 202 mm f/2.5 lens. Getting it tomorrow. Can't wait to use it.

  5. Sony 135MM Pros:
    – Native to Sony. No hidden welded adapters inside.
    – Faster and more reliable AF. Better Video AF.
    – 380 Grams lighter.
    – Shorter and better weight balance.
    – Better contrast per Tony and best in class MTF curves per lensrentals report.
    – More aperture blades.11 vs 9.
    – Higher aperture range. Up to f22 vs f16
    – Closer focusing distance. 70cm vs 87.5cm.
    – De-clickable Aperture Ring.
    – 2 focus hold buttons.

    Sigma 135MM Pros:
    – Price

  6. There's a third one the rokinon has a 135 f2 for sony e mount. I bet it will be just as good if not better than those two for less money.

  7. Great review! Will you guys be making a portrait lens comparison between the new Samyang 85 mm f/1.4 compared to the Sony 85 mm f/1.4?

  8. To my eyes the Sony lens had a visibly better microcontrast and 3D-pop – judged from the figure's eye. The Sigma renders it a lot flatter.
