Yes, the Sony FE 70-200/4 OSS is "80 grams HEAVIER and slightly LARGER than Canon EF 70-200 /4 L IS", but following are the reasons why I went with the Sony FE version:
So, for me, the above considerations are worth spending the extra money on the FE 70-200 f/4 OSS
- I already have the EF 70-200 f/2.8 L IS II, so I don't want another EF lens of the same FOL
- Although I really like the EF 70-200, if I want to use it on my a7 or a6000, I need to use my metabones adapter which takes away the weight & size advantage and not to mention slow AF
- Being a native lens the Sony FE 70-200 f/4 OSS auto focuses really fast and accurately like a machine gun on my a6000
I totally agree. Had i bought an A7/R i would also have purchased native lenses with at least halfway decent AF. However, i find sony lens pricing even more outrageous than canon's. Not only fe lenses but also other zeiss branded glass as well as almost all of the sony G lenses (a-mount).
Lens choice is one more reason why i would really like to see and buy a canon FF MILC ... along with a) decent mid-price lenses and b) outstanding high-price L's ... Like 70-200 2.8 II and 4 is, 24-70 2.8 II and 4 IS ... Of course in a new native short flange distance mount.
