[QUOTE="lokatz, post: 633686, member: 43924"] I can only speculate here since it's really not an apples-to-apples comparison, but the magazine I mentioned, ColorFoto, tested both lenses on full-frame D800. (Unfortunately, they did not test the Tamron on DX.) The Tamron got an IQ score of 63.5 (7 below average), with the Nikon 300 PF at 83.5 (13 above average). The TC does affect IQ some, but my testing convinced me to go with the TC-20 instead of simply up-zooming in Photoshop because of better sharpness, so I'd still expect the 300 PF to be a clear winner at 600mm. (Interestingly, Tamron's newer and pricier G2 scored two points lower on IQ than the old one. ) [/QUOTE]
