I recently bought an EL-NIKKOR 50mm f/2.8 (not the 'n') and attached it to my Z8 as per reverse lens set up. Was really excited to play around and see the results.
To my disappointment all I'm getting is a big blur! Everything seems to be attached properly, lens is ok, but zero focus from ANY distance and apperture. No idea what I'm doing wrong.
So regardless of what quality this setup might bring, using my Laowa seems to be a whole lot easier even without AF.
Any suggestions?
As suggested by Jones Longshot your best bet is to show your setup, in order to see if there's something else besides the lens which might be worth taking a look at.
Two things which come to mind though:
1.) Given that you try to use the lens in a reverse setup I'm assuming you want to use it for high-magnification macro work. To my knowledge the El-Nikkor 50 mm f/2.8 (non N) is not known as a particularly good lens for that. That being said it also shouldn't be a bad one. But keep in mind, that if you're going to compare your results from an old used enlarging lens, which is not considered the cream of the crop, with a high quality modern macro lens (which most of the Laowa offerings tend to be) will be tough for the former, unless you really have a good sample + a highly optimized setup.
2.) For assessing the quality of the lens itself, starting with a stacked setup usually isn't the best option. Just take a couple of close-up/macro samples with the lens in its original direction (if you have the means to adapt it yet) or reversed, but without the tube lens. If those results are not what you consider reasonably sharp and detailed, you likely won't get good results in a stacked setup either, where a lot of other things start to factor in.
From my (frankly quite limited) personal experience the El-Nikkor 50 mm f/2.8 (non N) should at least provide something like that close-up (wide open):
This is from a really well-worn sample, so ideally yours should be better...
But as mentioned before... your setup is what matters the most, because we don't even fully know how you focus that lens yet, unless I've missed something.
