I had the opportunity to get up close and personal with the resident Blue Jays at our cabin and captured this one with my new 300 F4 AF-S and D7100 combo. First is shot full frame and second is 1.3 crop.
Excellent sharpness and detail. Like the performance at ISO 1000 too. I often shoot with that lens, not so often with the 1.4 TC attached. As it happens I just shot with that combo yesterday (young sparrows), and results were pretty good. Hoping to get those posted soon. Not the same ISO latitude (mine were shot with D300s), but from what I can see the sharpness is definitely there. These shots are making that D7100 more tempting...
Thanks so much Dave - I think a great deal of the sharpness is inherent to the D7100's lack of an anti alias filter. However this new 300AF-S is very sharp even with the 1.4 converter. I don't have a 1.7 like you so I can't comment on the sharpness with that converter. I also shoot only High/Fine jpegs and post process in Photoshop elements, and haven't found the need to shoot Raw for my uses.
Great images Al. Had used the Kenko 1.4 tc with this lens on the D300 and found the Nikon tc much better than the Kenko,on the D300. The Nikon 1.4 seems quite a bit better than the Nikon 1.7 tc on the 300F4 mounted on the D7100 from what I have managed to shoot hand held. Never tried the Kenko with the 300F4 and D7100. On my 70-200mmF2.8 lens,the Nikon 1.4 and 1.7 tcs both seem very sharp.
I must have a good copy of the Kenko - in addition to great performance on the 300AF-S it performs really well on my 500P F4 and my Tamron 70-200 2.8 as well. It did so on the D300s also. I use the 300+1.4 combo mainly on a tripod with the D7100 as I find myself shooting in low light situations quite often.
I was considering the Nikon 1.7 TC + 300 AF-S with the D7100 - have you tried that combo on a tripod or just hand-held?
I've only tried the 1.7tc hand held. The results were very,very good but with the 1.4 the results were so much better that I never went back to the 1.7 and just crop to get that effect. If I think of it I will try it out on a tripod and let you know,unless you already have done so.
Al, I did a unscientific test with the Nikon 1.4 and 1.7 tcs from my tripod. Shot a Red-tail Hawk from the same position then in pp cropped so the bird seemed to be about the same size and then processed both the same in NX2. Resized in PS4. Both shot in DX,not 1.3 crop mode. The 1.4tc shot was cropped to 31.8% and the 1.7tc to 25.6%(if that means anything). Maybe a smaller subject from a farther distance would have been better for this test. My old eyes do see slightly better IQ with the 1.4 but a smaller subject with a bigger crop might give much different results. I don't think you can go wrong with the 1.7tc and you can find used ones around now that many are opting for the 2.0tc.
