alan_kovarik Posted December 29, 2017 Share Posted December 29, 2017 Hi. I just bought Nikon 55mm f/2.8 AF MICRO-NIKKOR. Ken Rockwell says its probably Nikon's sharpest lens ( and the sample images I saw on the internet are extremely sharp. However, the lens I bought is extremely soft. Its actually the less sharpest lens I had (even my cheap kit lens is much sharper). I have Nikon D3300. Where could be the problem? Do you think there is something wrong about this lens or am I doing something wrong? (Of course, I am focusing manually) I try to upload some images tommorrow.

photo_galleries Posted December 29, 2017 Share Posted December 29, 2017 Could you upload some images? What exactly are you doing you are shooting--handheld? lighting? aperture? shutter speed? etc... It is a very sharp lens in general, so unless you received a damaged lens, it could very well be user error. Link to comment Share on other sites More sharing options...
conrad_hoffman Posted December 29, 2017 Share Posted December 29, 2017 That should be the sharpest lens you own. Just speculating, they're known for stiff focusing due to the grease going hard. It's possible somebody took it apart to service it, and got something wrong on reassembly. I've got a couple, plus one I use at work, and they're all sharp as a razor.

alan_kovarik Posted December 29, 2017 Author Share Posted December 29, 2017 I used tripod. 1/160 shutter speed, ISO 100, f4.0. And speedlite reflected from a foam board. I also tried to shoot some images with my kit lens with the same settings (I was manual focusing with both). The kit lens was much sharper (but I noticed It was set to f8). Here are some quick tests. My kit lens was probably se to a different focal length, but both images are 100% crops. I try to shot some better tests tomorrow.

alan_kovarik Posted December 29, 2017 Author Share Posted December 29, 2017 I know its a bit underexposed. I didnt use any adjustments in postproduction. Link to comment Share on other sites More sharing options...
robert_bouknight1 Posted December 29, 2017 Share Posted December 29, 2017 Definitely does not look sharp, and it should be a bit sharper than the kit lens. How did you achieve focus? I have a difficult time with manual focus through the viewfinder on modern cameras with the brite view screens. Live view zoomed in is the best way to verify manual focus accuracy.

alan_kovarik Posted December 29, 2017 Author Share Posted December 29, 2017 I used zoomed in live view. Link to comment Share on other sites More sharing options...
robert_bouknight1 Posted December 29, 2017 Share Posted December 29, 2017 If all images are properly exposed and focused carefully with zoomed live view look like the one you uploaded, I would return the lens. Link to comment Share on other sites More sharing options...
Vincent Peri Posted December 29, 2017 Share Posted December 29, 2017 If it were my lens, I would return it before too much time passes. But first, try at a higher shutter speed. If that doesn't help, test the lens with another camera (friend's or camera store's). Link to comment Share on other sites More sharing options...
alan_kovarik Posted December 29, 2017 Author Share Posted December 29, 2017 I bought it on auction website, so I am not sure if the guy will give me my money back. :) I try another tests tomorrow. Link to comment Share on other sites More sharing options...
Hector Javkin Posted December 29, 2017 Share Posted December 29, 2017 I would return the lens and stop reading reviews from KR. He's right about this lens, but it's a hit or miss proposition. He has, in the past, admitted that he enjoys making stuff up. That statement may still be on his "About" page, I won't bother to look. Link to comment Share on other sites More sharing options...
alan_kovarik Posted December 29, 2017 Author Share Posted December 29, 2017 BTW, the older 55mm micro lens has much shorter focus throw. Its much easier to focus with the kit lens. Link to comment Share on other sites More sharing options...
conrad_hoffman Posted December 29, 2017 Share Posted December 29, 2017 Sorry, I didn't notice "AF". It's the old ones that have the grease issue. It should still be way better than that, so see if you can return it. Link to comment Share on other sites More sharing options...
burchanda Posted December 29, 2017 Share Posted December 29, 2017 Do not manual focus when testing the lens because you will introducing another variable. Image shown out of focus.for what ever reason. You could have purchased damaged lens. Take picture of a ruller at 45 degrees angle and see where is the focus point or have the lens tested by Nikon Link to comment Share on other sites More sharing options...
Vincent Peri Posted December 29, 2017 Share Posted December 29, 2017 I bought it on auction website, so I am not sure if the guy will give me my money back. If it was eBay, you can request to return the lens because it is defective. Follow eBay's instructions to return the camera. You will even get a postage paid shipping label to print out and attach to the lens package. Mail it back and wait for the seller to receive it. If he doesn't issue a refund by a certain date, go back to eBay and for eBay to issue the refund. Good luck. Link to comment Share on other sites More sharing options...
alan_kovarik Posted December 29, 2017 Author Share Posted December 29, 2017 My camera cant manual focus with this lens, thats why I used manual focus. I did more tests. Now both lenses has the same settings (1/200, f8, ISO100, tripod, shutter release, manual focus, both images are 100% crops): Top image: 55mm Micro Bottom image: kit lens Link to comment Share on other sites More sharing options...
alan_kovarik Posted December 29, 2017 Author Share Posted December 29, 2017 F8 looks much better than f4, but my kit lens is still sharper. Link to comment Share on other sites More sharing options...
SCL Posted December 29, 2017 Share Posted December 29, 2017 This makes no sense at all "My camera cant manual focus with this lens, thats why I used manual focus." Just return the lens...and find another which works with your camera. Link to comment Share on other sites More sharing options...

alan_kovarik Posted December 29, 2017 Author Share Posted December 29, 2017 I tried different apertures (f/8 is rather ok, but still worse than my kit lens, f/3.5 is just out of focus, even when from a bigger distance). What do you think? Is it ok? f/8 f/5.6 f/4.5 f/3.5 Link to comment Share on other sites More sharing options...

photo_galleries Posted December 30, 2017 Share Posted December 30, 2017 (edited) Have you checked the diopter adjustment on your D3300? It's moot for your kit lens because it's an AF lens, but for a manual focus lens, it will matter. It's just one more thing to check, but it's likely that you'll have to return the lens.

Dieter Schaefer Posted December 30, 2017 Share Posted December 30, 2017 Have you checked the diopter adjustment on your D3300? Not the issue here because: I used zoomed in live view. BTW, the older 55mm micro lens has much shorter focus throw. And herein I believe lies the problem. I find it quite hard to manually focus using a magnified live view image simply because every time I touch the focus ring, the image dances on the LCD screen and it is quite impossible to tell if one has nailed focus. A short focus throw makes this even harder. Have you tried focusing via the viewfinder (and yield the advice above about the diopter)? Not sure the D3300 has that feature - but if it does, have you tried focusing via the "green dot" focus confirmation? Link to comment Share on other sites More sharing options...
conrad_hoffman Posted December 30, 2017 Share Posted December 30, 2017 (edited) FWIW, for some lenses the green dot can beat my eyes every time. For others, not so much. Where was the lens focused on the ruler? I mean intended, not where it ended up. Edited December 30, 2017 by conrad_hoffman Link to comment Share on other sites More sharing options...
mag_miksch Posted December 30, 2017 Share Posted December 30, 2017 maybe you are inside minimum distance, this is not a 1:1 lense what I remember Link to comment Share on other sites More sharing options...
