Bizair Posted February 22, 2014 Share Posted February 22, 2014 Has any body used both and if so, would appreciate detailing your experiences with IQ, weight, non IS v IS, and any other issues? There is quite a difference in price, but that is not my main concern -rather the better image quality but with lack of IS on the F2.8 verses perhaps lesser IQ but with IS on the F4. Loss of one stop on the F4 is not a particular issue with me. Thanks Ken Link to comment Share on other sites More sharing options...
