Ben Corwin Posted January 9, 2013 Share Posted January 9, 2013 Hello All. So I recently bought a GH3 and I am now considering getting Panasonic's new 12-35mm lens. One of the developing topics about this lens, which seems to be making it's way into forums everywhere, is that the aperture "jumps" or stutters through the zoom range resulting in abrupt exposure changes. So I have to ask, is this something anyone's experiencing when using it with the GH3? Or is it only an issue when using it with a GH2?

powderbanks Posted January 9, 2013 Share Posted January 9, 2013 that happens with any non-fixed aperture zoom lens...but i just saw that it's a set 2.8 aperture. definitely odd, but it seems like it would be an issue on a lens by lens basis, not so much the camera bodies Quote Link to comment Share on other sites More sharing options...
Ben Corwin Posted January 9, 2013 Author Share Posted January 9, 2013 Hi powderbanks, Thanks for replying. What I've read is that Panasonic lenses have issues because they are close to 100% electronically controlled lenses with very little mechanics inside. Because of this, the lens is constantly talking to the camera even when the camera is set to full manual control. Consequently, when you zoom through the range of the lens, the aperture electronically compensates with the movement of the optics to maintain a 2.8 aperture. Unfortunately for us, that electronically controlled aperture compensation is not a smooth transition at all, at least on the GH2 as seen below. http://www.youtube.com/watch?v=u2vjROGkgUA So what I'm hoping is that maybe the GH3 has a better way of communicating with the lens when zooming. It would be nice to have a constant aperture lens without awful and abrupt changes in exposure. Quote Link to comment Share on other sites More sharing options...

Ben Corwin Posted January 10, 2013 Author Share Posted January 10, 2013 Because of this issue? Can you be more specific? Quote Link to comment Share on other sites More sharing options...

zaz Posted January 10, 2013 Share Posted January 10, 2013 Ben - There was a lot of talk about this lens creating moire. However when Andrew tried it at a Panasonic shoot, he said it was very minor and nothing to worry about. BUT, he also added that because the gh3 sensor captures with such high detail, softer lenses like the voigtlanders and slr magics tend to produce a much more desirable image. Personally, I'm very into the idea of having a totally sealed run and gun kit that requires no rain jacket and has image stabilization... But I'm still waiting for my camera ATM. Another strike against this lens is that if you plan to eventually move up to the bmcc, it be basically useless. Ben Corwin 1 Quote Link to comment Share on other sites More sharing options...
xenogears Posted January 10, 2013 Share Posted January 10, 2013 I have my concerns too about the Aperture issue with the GH3, but i read somewhere (trying to remembering where) this issue is do not happen on the GH3 but in the GH2. My other concers with the Lumix lens is the construction quality, my 14-140 lost the zoom band with the use; so, i hope this not happens on a $1000 lens.

GravitateMediaGroup Posted January 10, 2013 Share Posted January 10, 2013 When I originally seen the video above, I tried the same thing on mine. Returned it next day. Quote Link to comment Share on other sites More sharing options...

GravitateMediaGroup Posted January 11, 2013 Share Posted January 11, 2013 On your GH2 or GH3? gh2, even if it functions 110% properly on a gh3, as a lens, it still isn't worth it's cost. a voightlander or 2 rokinon cine lenses would be better, or a sigma 30 & rokinon 85. I "might" consider buying the 12-35 if it ever drops below $700, because that's all it's worth. Quote Link to comment Share on other sites More sharing options...

Unfortunately though, I've heard that the rolling shutter is massively exaggerated on the GH3 in ETC mode. Quote Link to comment Share on other sites More sharing options...
