Trioplan 50mm f/2.8 II

Very good value for the money I paid It may not be the best but very good value for the money I paid. It is very sharp after AF fine tune (+13 on D7200 for my copy). If somebody is looking for very sharp results and body doesn't support AF fine tune, they may have to live with whatever they got. Sharpness is poor in the corners wide open and it is noticeable as well. Tone, clarity etc - Overall the pictures looked very vibrant and pleasing. Editing raw files to my taste can change anything to what I want but I was able to get decent jpegs in the 'standard' picture control mode in D7200. Audible noise, build quality - AF motor is noisy especially if travels through the full range. Generally that is not the case and shutter release is much more louder anyway. Build is decent (mostly plastic and rubber) and feels much heavier compared to kit. Focus - I had front/back focus issues at f2.8 because of the poorly built AF drive system of the lens. D7200 is very fast to focus on distinct patterns and it is often too fast for this lens mechanism to handle. Final focus settles one or two centimeters before or behind the actual point. It happens randomly and I had to half press the shutter button once again (or twice) for a final adjustment from the position it previously stopped. And this method worked quite well. Continuous AF mode also helped as I half press and hold it, camera readjusts the focus (you can hear the tick-tick sound it is correcting the position). Also I have no problems with focus in live view, it worked very well. My copy is made in Vietnam.Read full review

Not sharp. Inaccurate focus Tamron 17-50mm: I bought this lens and after using it for almost a year, I can say the images aren't that sharp, the focus is lost in many important pictures. It is really hard to get a completely focused picture.

Tamron SP 17-50 f2.8 XR DiII DX Nikon Mount This is a very sharp lens. Let’s start with that. Build quality is good, constant 2.8 max aperture, rather quick focusing, compact, good focal zoom range for a walk around lens. Takes 67mm filters. Even shooting into a bright scene with sun, it does nicely. All in all a good buy 👍🏻
