EF mount might die out gradually. and my main camera are two sony full frame bodies now. But I also have a GH5 and a bmpcc 6k from my friend. I mean I think m4/3 will still be around and company like black magic and zcam will continues to launch cameras with EF mount. And APSC format will still be relevant. For all those reasons, I am still keep this lens as well as the 18-35 f1.8. They are just so good both mechanically and optically.

Built solid, smooth action, and Crystal clear optics. Nice round bokeh. One of the best lenses I've ever owned.

yes it breathes. yes it lacks stabilization. but the image quality is incredible for the price.

That's the sharpest lens I've ever seen. I've used many primes from Nikon and the 18-35mm (that was a lot sharper that the Nikon ones)... But this 50-100mm is definetly sharper than all. Also, I've heard complaints about the focus, but did not experience any with this one (have bought the dock just because I had some with the 18-35mm being a little bit out). I am using the Nikon D5300 and it nice to take portraits, the bokeh is nice and has a focus. If you don't like heavy lens, this is not for you though. I was using it with a manual flash and it was really heavy.

This was my go-to lens with my Nikon D7100 before I went full-frame. It's a bit heavy, but what a wonderful lens, especially in low light. I tried it on my D750 and D850 and decided I couldn't justify selling it back to B&H. Here's couple of recent handheld shots from a walk in the garden with my Nikon Z6ii. I love the bokeh and the color rendition. On the cropped sensor it acts like a 75-150mm lens. I bought it mainly for shooting dog show movement shots in lousy indoor lighting, for which it works great. On the full frame it works in DX mode as a true 50-100mm f1.8. I haven't had any vignetting problems with any of the 3 full framed camera bodies that I've tried it on. Occasionally I'll use it for dog show movement even though I have several nice full framed lenses to choose from.

My wife purchased this lens as a general lens as well as some portraiture. She is enjoying the lens so far.

We are using this lens on an older Black Magic Design Studio Cam (with a metabones adaptor) and it works beautifully, especially in low light applications.

So far I've been very satisfied with this lens. I use it primarily to shoot high school football games in low light situations. I am using an Nikon D7200 and this replaces an older Nikon 70-210 that was giving me fits. I've shot one game in low light (high school stadium lighting is horrible) and it was the best shoot I've done. My usable shot percentage was very high and I didn't experience focus issues that some have discussed. Very satisfied for now.

First a little context, I started getting serious about photography 3-4 years ago, planning to travel upon retirement. I have real deficiencies that affect my shots because my hands are not stable and my vision is fuzzy. I have a Sony a6500 which really helps with image stabilization, focusing and being light weight. I bought a Sony 1.8/50 prime and the fast lens really made a huge difference because it minimized shake even more.
I had been looking at this combo for quite some time because it was really the only one I saw that was going to give me f 1.8 start to finish and cover the range from 18-100. But I kept having second thoughts because of the weight which wouldn’t work well with my not so steady hand. I finally ordered it, took it out of the box and basically spent two weeks staring at it, picking it up and putting it down. Finally I decided I needed some practice with it.
I pretty much fell in love. The weight does not really add to the shake because it is so very fast, even at smaller apertures I can keep it above 1/320 of a second. The pictures are very good, the stabilization works with my camera and the focusing is perfectly integrated and locks in well. I will probably use it mostly with a tripod but I don’t have to in fast conditions.
So in conclusion even for someone like me who is more enthusiastic than skilled these two lenses are going to let me shoot faster and take better photos because they work perfectly with my camera to overcome my shortcomings. I did have a couple lower range zooms with f 4 all the way up but 1.8 is a game changer.

started using this instead of a 50mm prime. Been using it with my only crop camera, My Canon EOS Rebel T6s. It has the benefits of wide aperture that a prime brings, but more versatile. At a fair price of $1100, I highly recommend this to novices and professionals (as long as theyre fine with crop) alike.
