In a word, this is a fantastic lens, in terms of its optical properties. Extremely sharp lens even wide open. I use this lens at f1.8 most of the time and find that the only reason to stop it down is for more depth of field, or lower the shutter speed. I haven't shot any brick walls with it to check corner sharpness or distortion; only have used it as I normally would and it has not disappointed me, optically. It's a far departure from the serviceable, but mediocre 16mm f2.8 pancake.
The optical stabilization system works very well, in still photo or video. In fact, this is one of the best features besides the excellent optics. Very effective and easily gives two to three stops of usefulness. Despite my wish to have in-body stabilization on cameras, I still prefer in-lens stabilization system. It's far more effective as the system is tailored and optimized to the specific lens.
In terms of build, it's quite acceptable. The lens is surprisingly light weight despite the use of metal for the mount and outer lens barrel. It's no Leica in build quality, but few lenses are. For that, you will have to fork out a lot of cash, but I think it's a good compromise between cost, weight, and build quality.
The only gripe I have is the auto focus speed. It's painful if you are used to DSLRs or the later Olympus/Panasonic models. To be fair, the slow speed is probably not totally the fault of the lens, but the current NEX system as a whole. It's worse on wake-up from power save mode when you have to rack the focus from closes to infinity. If you need to shoot something quickly, and the camera is in sleep mode, by the time the camera wakes up and sets the lens in focus, the opportunity is often gone. I think this is the biggest problem for the NEX system at the moment. I am so used the quickness of my 1D III when I need auto focus, the NEX-5/5N/6 just drives me crazy. The only thing that saves my insanity is the fact that I shoot more manual focus lenses on the NEX-6 than AF lenses.

Love the snowy shot especially, almost looks like a mechanical dog with that front leg position. Lol
ReplyDeleteThanks Tim Ball.
DeleteHallo Yu-Lin,
ReplyDeleteI don´t have a DSLR anymore and also no OlyPan. Only my old NEX-3 and the NEX-5R.
And also the SEL50F18. It is not really usable with the NEX-3 in terms of AF and also slow with the 5R V1.00. But with the new Software on both lens and cam it seems really usable. It´s ok if you work in a limited distance range, not on both ends. Did you try the new software and is it still so much slower as OlyPan?
Allways good aperture!
Jochen
Jochen, I did indeed update the software, both for the lens and the NEX-6. The 50mm f1.8 OSS now supports phase-detect AF but is still slower than Oly and Panny in terms of focusing speed, especially in low light. It's usable for me, but wish it were better.
DeleteKeen to know the shutter speed on the piano shot and if it was and held. That's the important stuff when evaluating the effectiveness of the stabilisation
ReplyDeleteShutter speed was 1/80s at ISO 2000. I set the camera on Aperture Priority most of the time and the camera just sets the correct shutter speed. Haven't really tested thoroughly on the stabilization but it has been effective for the time that I need it.
