alan_kovarik Posted December 30, 2017 Author Share Posted December 30, 2017 (edited) maybe you are inside minimum distance, this is not a 1:1 lense what I remember Yes, it is 1:1 lens. I am was not inside minimum focusing distance. BTW, all the images are 100% crops. Edited December 30, 2017 by alan_kovarik Link to comment Share on other sites More sharing options...
marcel_carey Posted December 30, 2017 Share Posted December 30, 2017 Try shining a flashlight through the lens to see if there could be inside dust or mildew. It does seem to be quite a bit soft. Were shots made on a tripod and focused through LV? Link to comment Share on other sites More sharing options...
ben_hutcherson Posted December 30, 2017 Share Posted December 30, 2017 Yes, it is 1:1 lens. I am was not inside minimum focusing distance. BTW, all the images are 100% crops. None of the MF 55mms go to 1:1-the closest any will get is 1:2. Still, though, the photo of the ruler shows that you are well within the focus range of the lens and there is definitely something wrong with it.

mike_halliwell Posted December 30, 2017 Share Posted December 30, 2017 If that's the best the lens will do at zoomed in LV manual focus, it's been messed with...or maybe a loose element...it's nearly 30 yrs old AND an early AF mechanism Sure, the image will get better as you stop down, but it's still shot. Return it ASAP. Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted December 30, 2017 Share Posted December 30, 2017 I totally agree with Mike. The 'bokeh' on that ruler image looks doubled up, and it definitely shouldn't. Send the lens back. It's a dud! Link to comment Share on other sites More sharing options...
jim_momary Posted December 31, 2017 Share Posted December 31, 2017 Alan, here is a quick sample I shot this evening using that same lens. First image is the whole frame, the second image is a crop and represents about 2% of the frame's coverage. Shot at F3.5, on tripod, with led lighting, shutter speed about 1/2sec at ISO100 (on tripod, obviously). I focused manually using live view zoomed all the way in. Granted, it is black writing in a white background which "enhances" apparent sharpness, but you will note this lens should be sharp as a razor blade when used properly and all things are OK with the unit. Images follow- Link to comment Share on other sites More sharing options...
jim_momary Posted December 31, 2017 Share Posted December 31, 2017 Zoomed in view of that frame: Link to comment Share on other sites More sharing options...
mike_halliwell Posted December 31, 2017 Share Posted December 31, 2017 The idea you can get gravy with an included brush is truly amazing....:cool: It looks a bit better, but I think I'd still send it back and get a 60mm f2 tamron macro. Mine @ f4 it's so sharp, you could cleanly cut a squishy tomato. It's also my favourite lens for focus-stacking on my D7200. Link to comment Share on other sites More sharing options...
