Well, close, but apparently I wasn't finished buying ultrawides.Thanks for your reply, saw it only now. I too love the Batis lenses and quite enjoy the 16-35f4. Seems we have similar taste ��
Frankly, I'm not sure what 'inspired' me to buy my 2nd Zony 16-35/4 in a few months (blind optimism?); it too did not perform well(1) and it's sold.. Finally I admitted to myself that the best-performing UW zoom that uses screw-on filters apparently is the Sony 16-35GM.. I think its $2200 price kept me from considering it, but I now have TWO here, one rented(2) and one purchased from B&H.. The rental arrived first and impressed very positively including the phillipreeve.com tests(3) for decentering; the new one performs just as well and I'm keeping it.
I've retired the Batis 18 but will keep the 40 in my bag until I decide it's redundant with the 16-35.. So I'll have the 16-35GM, Batis 40/2 and 85/1.8, and Canon 70-200/4/L/USM/non-IS plus 1.4x(III) extender, plus the Canon 50mm TS-E Macro (gen.3), the best-resolving and most-versitile lens I've ever owned.
...oh ya...plus the Sony 24-105/4.
(1) What this lens needs is a SQUARE sensor 24mm tall; that way one wouldn't see the lens's soft sides.
(2) From LensRentals; $168 for seven days including $25 shipping both ways and $8 Arizona salestax.. Will be returned tomorrow the 12th.
