i was just looking at what lenses are available if i replaced my FF canon stuff with micro four thirds

i will want like for like ..as we know a 25mm MFT lens is same as a 50mm FF and we know it needs to be 2 stops faster for same depth of field (1 stop faster for APS-C)

i have made i list up.. its a bit hard as often no direct replacement ...i was surprised to find that like for like lenses are all the same size in fact MFT seam a little bigger than the FF a equivalent

So maybe if you want a lighter camera bag it can be achieved with slower lenses than a smaller format ...because basicly that what you are doing anyway

I did put the weight in but it as much to do with how its built than size

some are not bothered about fast lenses and shallow DOF

telephoto zoom

Canon 70-200 F4IS FF 76mmX173mm 67mm filter 760g

olyimpus 35-100 F2 FT 97mmX214mm 77mm filter 1.65KG

Panasonic 35-100mm F2.8 MFT67mm x 100 mm
