Dylan777 said:I have never hand-on 4/3 system before. I do not how small and light weight they are. Having to shoot with a7, a7r and a7s I don't know if Sony or other companies can go any smaller or lighter for 35mm sensor. Their current native FE 28mm, 35mm and 55mm are great from size to weight.
And image quality, for that matter. I own m4/3 as well as an a7r and a7s (and a couple of Canon dslrs, FF & APS-C) and yes, m4/3 is definitely lighter and smaller, especially when you compare lenses with similar angles of view as lenses get longer (compare, say, the Olympus 45mm 1.8 to any 85-100mm prime, or, especially the Olympus 60mm macro to any 100mm macro (does anyone make a 120mm macro?). (There are ways to get small FF lenses, but you end up in vintage MF territory here, and they often end up weighing proportionately more since they're usually (beautifully made) metal.) But of course you end up having to compare more than just angle of view since the crop factor affects everything else, so as often as not there's no direct comparison to be made; trying to chase shallow focus, for instance, and you end up paying a lot for f0.95 lenses that are usually heavy and MF and still not as fast, in FF terms, as f1.4. And for all that m4/3 are impressive given their sensor size, I would be rather surprised if you thought any m4/3 gave you comparable results to what you can get from your a7s in just about any light. Since acquiring my a7r and a7s I've stopped using my m4/3 equipment; I should sell it....
