fit my Sony a7 r iv with 24-105 mm lens and Godox V1 flash. Durable.

Super fast F1.4, this lens covers all the bases, from quality glass to weather resistant sealing. This lens is perfect for landscape photography and for traveling light. I'm solely a prime lens user, and this one is always in my bag.

Inexpensive for the speed (f1.8). You can buy an f1.4 version of this lens, but it's twice as much money. Very pleased.

I finally got this super fast 35mm lens after years on the original EF (nifty) 50mm f1.8 and I'm blown away. The colors seem to have a cooler tone than with my 70-200 f4L IS or 16-35 f4L IS (possibly that Blue Refractive optical element) but this is preferable to me. I often regret stopping this lens down in any other setting besides direct sunlight because it is super sharp corner to corner at f1.4 and everything is in focus when focused near infinity. The closer you get to your subject at f1.4, the more your photo becomes an elegant work of art with bokeh that just melts away but yields a nice wide angle view of the subjects environment. Fast enough to catch that split second smile on your significant other's face and give them the separation from the background that just makes them pop. People become electrifying when captured with this lens. Every photo makes me smile with joy and love. If you are a photographer and you love capturing beauty in a setting, you need this lens. Don't fool yourself by saying you can't afford it, sell all your slow f4 zooms and maybe a toe to capture the world through 35mm.

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on.But after-service support was pretty helpful in telling me this

Seems to be working nicely without any color cast. I've mounted this to a Rokinon 24/f1.4 and a Nikon 24-120/f4, both on a D610. I've made beautiful exposures with both lenses. Threads are cut nice and sharp. Glass, not plastic. For under $30, I wouldn't hesitate to buy another.

I use it with my 15mm fisheye f2.8 (mostly), but also with my 50mm f1.4. I did try 24-70mm and also 70-200mm and its good also, but the look of the gear was weird and funny. But the lenses worked very well :)

Product is compatible to 58 mm lens mount and working good till the time I test this one in open and edit my review.
