X Vario lenses

Anyone using the Lumix G X Vario zoom lenses?

Curious as to the actual power zoom function on these 2 lenses. Are they smooth? Do you see exposure shifts during zoom?

Thanks

Re: X Vario lenses

The 45-175 is a decent lens. The power zoom lever is small and not very subtle but the manual zoom works decently for small zooms. A full manual zoom requires a lot of turning and isn't very practical. The exposure doesn't shift noticeably in the few times I've used it with live zooms.

The 14-42 is a different matter. The exposure shifts suddenly with zooms making it near useless for live zooming. The lens does not have a manual option for zooms or focus. It can be useful if you are shooting interviews and want to zoom in or out between takes and not want to worry about the focus if you have the focus set already. I have one but haven't had a situation where I couldn't use the 14-140 or the 20mm to better effect.

All said, a decent semi-pro video camera is 1000% better at zooming than what you can get for a DSLR camera.

Agree totally with William relative to X 14-42. Live zoom is useless. I also see no advantage to this multi-coat lens, as flare is an even bigger issue due to no lens hood.

I highly recommend the Lumix 14-45, but not this GX 14-42.

Re: X Vario lenses

Thanks, BIG disappointment. I don't need to zoom often but it would be nice to have the option. Jumpy exposure is a non starter. What was Pana thinking? The 14 42 sounds useless.

Is there another choice in a W/A power zoom? Perhaps from Oly?

Ed - I'm looking at the Olympus 12-50 f3.5-6.3 EZ lens ($499 from http://www.amazon.com/Olympus-M-ZUIKO-DIGITAL-F3-5-6-3-V314040BU000/dp/B0073AIXOA or http://www.adorama.com/IOM1250MSBK.html). Power zoom and splash resistant. This is the lens I'll get with the GH3 (assuming it is weather sealed too ;)).

ephotozine sample video:

Sadly, Panasonic's constant aperture moisture-sealed lens http://www.amazon.com/Panasonic-H-HS12035-LUMIX-12-35mm-Series/dp/B00843ERMW and doesn't have a power zoom :(

Cheers,

Bill

Re: X Vario lenses

The Oly 12-50 has some very positive user reviews for it's power zoom mechanism which more than I can say about the Panasonic zoom mechanism. Unfortunately it does not have OIS which is a hindrance for handheld video work. The very expensive Panasonic 12-35 has OIS but no power zoom. It's possible that the 12-35 has a smooth, easy to use manual zoom but I haven't seen mention of that yet. Many people feel that live zooming is bad so it doesn't get mentioned in reviews much for these cameras.

Re: X Vario lenses

Thanks Bill, Oly looks like a much better option.
Any compatibility issues with a GH2?

Re: X Vario lenses

I think the camera was in auto exposure. as soon as the pan happens the exposure changes; before the zoom gets going. impossible to judge for sure...

Re: X Vario lenses

My opinion of the X zooms is they are a fancy option to win over the P&S crowd to interchangeable lenses. I handed my niece my GH1 and 14-140 to use and when she returned she said she had a hard time finding the zoom button! Neither of the Panny X zooms are exceptionally sharp lenses. They just go in and out at a touch of a button. I think that's all Panny had in mind.

Re: X Vario lenses

Since someone asked about it, The 12-35 has constant iris, very very smooth manual focus, and is sharp as heck for a 3:1 zoom. It's also not ghastly huge and comparatively not as expensive as larger systems' equivalent lenses.

Re: X Vario lenses

Who asked about the 12 -35?
I asked about powered zoom lenses for the GH2.

It looks like the same exposure change in the 14-42 X zoom, I hope I am wrong about that.

Trying to be helpful to anyone reading this. The available power zooms had pretty much been discussed, and William H. and Bill B. brought up the 12-35 and mentioned that they didn't know how well the manual zoom functioned. I filled in that info as best I could, FWIW.
