Pros: Build quality. Sleek design. Not really a lot of difference between having this mounted on the camera with my 120-300 S Sigma or the naked lens and of course it gives me a cheap way to get 600mm at least for portrait style wildlife shots and action that is not super fast. From what I have seen I would rate this ahead of the 2xTC's from Canon and Nikon when mounted on a 300mm prime lens especially when mounted on my Nikon D750. Others of course will disagree : ) Photo's taken after March/April would give a better indication of the performance as the Nikon d7100 required a AF fine tune of +19 before I started to get the most out of the lens/TC combo. Nikon D750 has not needed any adjustments.

Cons: Birds in flight I prefer the 1.4TC but I can still get pretty good BIF shots with the 2xTC

Opinion: OK, even the very best TC is going to be some sort of compromise over a prime that gives you the same focal length no matter how small that compromise may be. But if we are strickly talking about how this TC performs, I rate is as excellent. Also gives you a bargain 600mm that still renders satisfying detail/sharpness and color even at full zoom. Please remember this TC will currently only perform on a select few Sigma lenses so please see Sigma's website for compatabilty.

Pros: Impeccable, robust and tropicalized construction. Includes two very low dispersion SD lenses.

Cons: absolutely nothing.

Opinion: The TC2001 should only be used with the lenses to which it is dedicated! In combination with the Sigma Sport 70-200 f/2.8 it returns sharp images almost equal to the smooth used lens and autofocus absolutely does not lose its responsiveness. It still costs less than the respective of the brand body machine is this is certainly an advantage. I repeat, after reading the previous comments, ct should only be used with the lenses to which it is dedicated.... combining it with other lenses of different brands/types incurs at best malfunctions if not worse.

Pros: mf only manual (not pro)

Cons: Autofocus does not work,

Opinion: Why not work autofocus .....: rnAppena purchased and used with the zoom f2.8 Tamron VC usd, and with the Sigma 105 macro f os 2.8, the auto focus does not happen, you feel the buzz of ' af but everything remains blurred, only mf manual, use with Nikon D 800.rnQualcuno I can 'answer? Yet the data sheet says compatibility. rnForse must calibrate the Firmware ....., as expected on the latest Sigma zoom before use ...? rnrnringrazio, salutirnmatteozoffoli53@gmail.com
