next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - Klaus - 05-07-2011 Lovely lens - highly recommended: [url="http://www.opticallimits.com/pentax/618-pentax70f24"]http://www.opticallimits.com/pentax/618-pentax70f24[/url] next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - Guest - 05-07-2011 One thing I'm marginally confused in reading the verdict is that this lens lies between a 50f2 and a 85f2.8 both of which typically perform very well (esp when you get into the $600 price range). Add to that this is an crop frame lens do you really find this lens to be uniquely good for a relatively slow lens ? next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - goran h - 05-07-2011 Very interesting. This is one of my favorit lenses. I couldn´t imagine resulotion was so high, but what I really like with this lens is how it handles contrasts with perfekt skin tones and brilliant colours. Another interesting pentax lens is the 100/2.8 macro WR. Will it be tested? Göran next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - Guest - 05-07-2011 You2, I believe Yvon Bourque tested the DA 70mm and confirmed it functions well on 135 film. Many of Pentax's "DA" lenses are actually full frame. next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - IanCD - 05-07-2011 [quote name='Klaus' timestamp='1304774384' post='8115'] Lovely lens - highly recommended: [url="http://www.opticallimits.com/pentax/618-pentax70f24"]http://www.opticallimits.com/pentax/618-pentax70f24[/url] [/quote] Pentax looking really good..! Why are the resolution scales different for the K5 (up to 2750) and Nikon D7000 (up to 2900)? I thought they used the same sensor. That doesn't result in same resolution (scales)..? next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - thxbb12 - 05-07-2011 [quote name='IanCD' timestamp='1304804875' post='8121'] Pentax looking really good..!

[/quote] I suppose because the K5 has a stronger AA filter than the D7000 thus the slightly lower resolving power... next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - thxbb12 - 05-07-2011 [quote name='Klaus' timestamp='1304774384' post='8115'] Lovely lens - highly recommended: [url="http://www.opticallimits.com/pentax/618-pentax70f24"]http://www.opticallimits.com/pentax/618-pentax70f24[/url] [/quote] Thanks for reviewing this lens again Klaus. Looks surprisingly good indeed <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' /> In term of contrast how does the DA 70 fare (wide open) say in comparison to the DA 15? I own the latter one and find it very contrasty... And versus the FA 77? Thanks! next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - youpii - 05-08-2011 Nice lens I'm still waiting for Pentax to make mirrorless cameras to have very compact systems with the pancake lenses next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - joachim - 05-08-2011 [quote name='youpii' timestamp='1304818092' post='8124'] Nice lens I'm still waiting for Pentax to make mirrorless cameras to have very compact systems with the pancake lenses [/quote] Pancakes for mirror less are harder than for DSLR. On a DSLR you have between 1 and 2 cm extra distance between the mounting flange of the cam and the sensor. That helps keeping light rays less angled while the lenses are still small. next PZ lens test report: Pentax SMC DA 70mm f/2.4 Limited - Brightcolours - 05-08-2011 [quote name='joachim' timestamp='1304842363' post='8125'] Pancakes for mirror less are harder than for DSLR.

"the" pancake lenses as a result will not just fit on a camera without that mirror box. Just like with micro 4/3rds and 4/3rds lenses and Sony A-mount lenses on NEX, you need an "extension tube" adapter which makes the camera just as deep again. BTW, the distance between flange and sensor usually is about 4cm. |
