Picked up the new lens this morning from London Camera Exhange in Southampton. All looks good so far fitted it to D850 and did some tests. This Goldfinch on bird feeder is about 1/3 of the full frame. 500mm lens plus x1.4 not very good light in the wood so 2500 ISO 1/400 sec f8. This is lens wide open as it is f5.6 but with the x1.4 you lose a stop. I also found that in poor light auto focus not 100% with x1.4 but fine with out it. In better light no problem at all. Handls a dream so not sorry to see my big 500mm f4 go but can see the advantage of the f4 in poor light like I had today in the woods. Sharpness of images is good well up to 80-400mm lens but early days to say it is as good as the big 500mm lens. Weight and size is what it is all about. PS also had a play with the Z7 Attachment: Goldfinch1936.jpg (Downloaded 27 times) Last edited on Sat Oct 20th, 2018 11:33 by Graham Whistler ____________________ Graham Whistler |
