Next PZ lens test report: Sigma AF 8-16mm f/4.5-5.6 DC HSM (Nikon DX) - Klaus - 05-18-2011 I still have the Leica 14-150, oly 12-60 + 50-200 sitting on my desk. I am waiting for a price decrease of the E5 actually. Till then I will use the Gh2 with adapter. The Leica has a very decent AF speed here. It's a borderline thing for the two Olys. Maybe I will get the Oly 7-14. I just don't need high ISO or more than 12mp. I need quality.

I just can not find the 4:3 format visually attractive. Further, 4/3rds is not for everyone, because of the relatively limited shallow DOF possibilities. A shame the two Olympus lenses do not focus any faster for you.. at least the more bulky E5 will add IS to the Oly-lens mix.

[/quote] Yep, it also a mystery why Oly hasn't integrated the multi-format sensor into their MFTs. Same goes for the "plain" Panasonic Gs. It's actually quite nice to be able to choose between 16:9, 3:2 for horizontal setups and 4:3 for vertical ones.

Frankly Oly could also take an APS-C sensor and sell it as multi-format 4/3.

Concerning Panas multi-aspect sensors we don´t know about eventual contractual agreements between Oly and Pana. It is also possible that some aspects of the multi-aspect sensor concept as it is used by Pana represents patent-protected intellectual property. Regardless, in terms of marketing both companies, Oly and Pana, leave a lot to be desired.

At this pixel density Samsung could also make 26 MP APS-C sensors, if that´s considered to be useful <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' /> Next PZ lens test report: Sigma AF 8-16mm f/4.5-5.6 DC HSM (Nikon DX) - joachim - 05-18-2011 [quote name='Yakim' timestamp='1305668988' post='8460'] Joachim, Bob Atkins once made a [url="http://www.bobatkins.com/photography/lens_defect_survey.html"]Lens Defect This is most likely spam content[/url]. Have you seen it? [/quote] Hi Yakim, Thanks, I do not remember seeing this. It is a few years old by now. As Bob points out, most lenses are considered by their users as "good", but for Sigma there was a 1in5 for a bad one <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='' /> Joachim |
