Hi,

Its been a while since I posted and I now have a Panasonic G2 and GF2 which overall I am very happy with.

However as ever with progress being made with sensors and prices coming down I am wondering on the improvements that I may get from upgrading to the G3 or possibly switching to NEX 5 or even possibly my first DSLR! probably the D3100 or D5100.

My concern with the G3 is whether the IQ at low ISO's is actually slightly worse but improved at the Higher end. I mainly take pictures upto ISO800 so am wondering would I really gain anything IQ wise at and upto this level.

However I do have 3 children and taking pictures at their School shows at Christmas etc with the 45-200mm lens normally end up pretty noisy and therefore it would be nice on the odd occasion I need high ISO's to have it there.

This then makes me wonder whether the larger sensor of the NEX5 and or the Nikon D3100 or D5100 would be better overall?

I have never had an APS-C sensor size camera so I have no idea if there is any difference now at low and moderate ISO's when compared to say the G3. Certainly Gordon's review of the G3 seems to indicate not?

I would really appreciate feedback and some guidance.

Many thanks
Neil

Since it doesn't seem to me like auto-focus would be critical when taking pics of children's school shows, I think your money would be better spent on a fast/bright telephoto lens (and an m4/3 adapter for it). The 1-2 stop advantage of, say, a 70-200mm f2.8 would more than make up for the size difference between m4/3 and APS-C sensors.

Or if you can get closer to the stage, there's Oly's 45mm f1.8 (and upcoming 75mm f1.8).

Thanks for the reply.

I happened to see the Zuiko 45mm 1.8 Lens on Amazon recently and assume that would make a good choice for indoor shots with my G2 or GF2?

Thanks
Neil

With the 4/3 format's 2X crop factor, I'd find the 45mm (90mm equiv.) lens a little long indoors. But maybe you have a bigger house than I do.

Generally speaking, Panasonic's 20mm f1.7 (40mm equiv.) is more versatile, as it's more than twice as wide. And being a "pancake" style lens, it's physically smaller, which is something GF2 owners are usually looking for.

Best way to tell which one would be more useful to you would be to check the EXIF data on pics you've taken previously and see if the majority of them were taken at focal lengths of, say, 40mm or more versus 35mm or less.

Full disclosure: I own both an Oly 45mm and Pany 20mm - Mark

I agree with the above. Update your lenses, not the body.
