DonPilou Posted January 16, 2017 Share Posted January 16, 2017 Good evening! Following the comparison of three 50mm lenses, I am going to compare three 35mm lenses for ultraviolet portrait photography : the Nikon E 35mm F/2.5 , the Optomax 35mm F/3.5 and the Soligor 35mm F/3.5. For this comparison I used 3 Yongnuo yn560 IV unfiltered at full power, the same camera distance (1m) and the same EXIF : 35mm, F/5.6, 1/40s, 400iso. The focus is not perfect at each time... After the take of the shots, each file was processed the same way. Note : the shutter speed is not a real parameter here because the only UV light source is provided by the flashes. It only has to be lower than the synchronisation time of the flashes : 1/200s. Here are the results of the test : Nikon E 35mm F/2.5 Soligor 35mm F/3.5 Optomax 35mm F/3.5 The results show why I haven't used a 35mm lens since now ;) : the Nikon E 35mm F/2.5 is really bad in ultraviolet photography. Both Soligor 35mm F/3.5 and Optomax 35mm F/3.5 seems to have the same good performance, the histograms are closed, I notice a better sharpness with the Optomax 35mm F/3.5. Link to comment
Andrea B. Posted January 16, 2017 Share Posted January 16, 2017 Are the Optomax and Soligor supposed to be f/3.5 rather than f/2.5?? Link to comment
