This copy had two 'focusing issues'. First, this lens has a 'chip' that recognizes when your subject is in focus and indicates as much in the viewfinder. Snap a photo when the indicator says your subject is in focus and the resulting image will be slightly out of focus. This was an issue at all apertures.
Since I could not rely on the 'chip' to indicate when an object was in focus, I had to use my eye through the viewfinder. This wound up also being an issue. Images through the viewfinder would appear in-focus but would be out-of-focus in the images. This sounds like operator error, I know, which is why I had a friend bring over his camera body to see if he experienced the same issue. After a few dozen shots, he noticed the same two issues which left us scratching our heads. He theorized that the center of the glass may have been slightly distorted as grabbing a focus point in the corner of the frame usually resulted in a perfect focus. We also noticed that the only reliable way to get a good focus on a subject was to shoot in LiveView.
This lens was stunning when you could manage to get a good focus. Beautiful and sharp even at f1.4 and the bokeh was outstanding. I shot with this lens for 2 weeks before returning it for the Nikon 50mm 1.8G. The Nikon is not as fast, it's not as sharp wide open, it's not built as well and it's not as colorful and contrasty at the larger apertures, BUT what good is a stunning lens if you can never get a good focus? The AF-S Nikon works as you'd expect and it's half the price.
Kudos to Amazon for a seamless return process. If you're confident in your manual-focusing abilities, check this lens out and cross your fingers for a good copy. If it doesn't work out, just send it back.
- Take a good look at the product photos (the larger versions). See those little flecs on the paint job? They're much more obvious in person. I suppose one could argue that it makes the lens more grippy...but I don't think it makes a huge difference. Even the plasticy feeling lens hood has the flecs.
- The lens is big and heavy. About 40% longer than the 18-55mm FujiFilm f2.8 OIS.
- The lens caps are terribly cheap plastic.
- I did notice some magenta fringing around black on white edges. FujiFilm's matched lenses do processing to remove such artifacts. This does not have any electronic camera connection, so you get what you get.
- This lens (even without the hood) is too big and too long to allow close-up use of the built-in flash. It will block about 1/4 of the light at the bottom of the frame depending on your subject distance.
- The focus is smooth, but a little less-so than the 18-55mm FujiFilm (my only other comparison). Nothing noticeable alone, but switching between the two, you can tell the difference.
- The aperture ring is nice and clicky. If you shoot video, it may be a bit too had to turn as you will undoubtedly jerk your camera switching.
- Being able to focus down to 1 foot puts this in macro territory. Minimum focal distances and wide open aperture will give you very very shallow depth-of-field. Ink bottle photo for depth-of-field.
- Bokeh is ok. Nothing to write home about. Attached is an obligatory bokeh Christmas lights photo. Center of frame are nice and round, but they get very squishy as you move out from the center. The other silver shot is just tinfoil. The balls look octagonal.
On the negative side:
1.) It is big and heavy. It is not a lens I would take with me when I travel overseas. However, it still gets used stateside.
2.) It is easy to forget to change the camera from manual focus back to automatic focus when changing lenses. This can result in some poorly focused photos with the autofocus lens. However, this is not the fault of the Rokinon lens, but of the author of this review.
I have been using it with no issue "everything manual" but at least no $1,500+ from the Sony one
