next PZ lens test report: Canon EF 70-300mm f/4-5.6 USM IS - Klaus - 12-05-2010 [url="http://www.opticallimits.com/canon-eos/566-canon70300f456isapsc?start=1"]http://www.photozone...6isapsc[/url] Still very decent on the EOS 50D albeit quite comparable to the 55-250mm IS. next PZ lens test report: Canon EF 70-300mm f/4-5.6 USM IS - Tiz - 12-06-2010 Thank you. Is the difference visible (compared to the 55-250 on the one hand and the 70-200 f4 IS on the other hand)? next PZ lens test report: Canon EF 70-300mm f/4-5.6 USM IS - Klaus - 12-06-2010 [quote name='Tiz' timestamp='1291654986' post='4788'] Thank you. Is the difference visible (compared to the 55-250 on the one hand and the 70-200 f4 IS on the other hand)? [/quote] Towards the 55-250 - not really except for vignetting. Towards the 70-200 IS - yes. next PZ lens test report: Canon EF 70-300mm f/4-5.6 USM IS - Tiz - 12-06-2010 [quote name='Klaus' timestamp='1291656082' post='4790'] Towards the 55-250 - not really except for vignetting. Towards the 70-200 IS - yes. [/quote] Thank you. Is it possible to generalize this by saying that differences of about 100 LW/PH are hardly visible outside the lab and differences of about 200 LW/PH are visible (but still not huge)? next PZ lens test report: Canon EF 70-300mm f/4-5.6 USM IS - Klaus - 12-06-2010 [quote name='Tiz' timestamp='1291663829' post='4792'] Thank you. Is it possible to generalize this by saying that differences of about 100 LW/PH are hardly visible outside the lab and differences of about 200 LW/PH are visible (but still not huge)? [/quote] It all depends. The subjective quality perceptions needs to take CAs into account. Assuming the CAs are about equal I'd say that normal mortals will see a difference from 250 LW/PH onwards. |
