Rokinon 50mm f/1.2 Reviews

Workable for family portraits on a budget

By Scott
Rated 3 out of 5
Date: 2018-01-19

Wide open, it's not especially sharp compared to e.g. the Olympus 45 1.8.� But that is often a tradeoff with large-aperture lenses, and some don't mind a bit of softness in a portrait lens.� If f/1.2 on a budget is important, you can handle or learn manual focusing, and you aren't making large prints, it might be perfect.� I've grown to like it, but I wish I'd bought it on sale. Note:� If Sigma releases an autofocus 50 1.4 with sharpness and price comparable to their 30 1.4, this lens would lose most of its appeal.

Wonderful build and optics, but not a small lens

I am pretty shocked at how fantastic this lens is optically. It is amazingly sharp edge to edge right at f1.2 and really doesn't need to be stopped down. The Bokeh quality it top notch and the colors and contrast are great. Mechanical operation is solid and smooth and the build is very good. The only drawback for this lens is that for micro 4/3, it is fairly big and heavy. But, that can also be said of the closest AF lens alternative, the Panasonic Leica 42.5mm f1.2. You probably know this is Manual only lens. So if you aren't comfortable with that, this is not for you. With many of the newer cameras, focus peaking and center magnification make it easier, but it's still not as nice as a quick AF button (or face detect AF since this is most likely a portrait lens). TL;DR - If you are OK with a manual only lens, this definitely holds its own against the super expensive Leica 42.5mm F1.2 and the best AF lenses in the system. It's simply superb.

Not acceptable for my purposes

By Phil

Based on the previous reviews, I was hoping for a fairly sharp lens. But after some thorough testing, I am quite disappointed. On my micro 4/3 Panasonic GX85, the sharpness of this lens is fine at the center of an image, but falls off to an unacceptably soft blurry look at the edges. And, focusing this lens is very fiddly. Even with a good zoom on the camera back display, establishing max sharpness takes a very delicate touch. I bought this fast lens for shooting large flat paintings in controlled lighting settings. When I capture a 4 ft wide painting at f 5.6 (about 12 ft from the target) the image became unusably soft at the edges. Sharpness improved at f 11. I sent the lens and some of my test images back to Rokinon to see if they agreed that it was defective. They said it was within spec, and not defective. That's disappointing, and this lens is going back to B&H.

Loving It!

i bought the 12mm Samyang and love it, now this 50mm Rokinon, I'm loving it too. They are made by the same company. Incredible lenses! The images look like those made with far more expensive glass. I was originally worried about going back to manual focus, but I'm actually enjoying it, and for many shots it's an advantage. I love having a real focus ring and aperture ring on a lens again. I have old, and very experienced eyes. The only thing I'm really missing so far is the metadata, that's why I gave it four stars.
