Sigma APO Teleconverter 1.4x EX DG for Nikon Digital SLR Cameras Reviews

Customer Rating:
Summary: Teleconverter
Comment: Nice and easy to use, thin and affordable converter just take you're standard lens and add 1,4 to the f value and you got the number i.e 2,8 X 1,4 = 3,92 or f/4 so it is good for everyday use

Summary: Excellent add on
Comment: For the past year I have used mine on a regular basis with my Sigma 150 macro lens. This creates a 210 F4 macro that is amazing. It is not possible to tell, by looking at the pictures, which were taken with or without this TC. Buying this gives you a second lens of equal quality for a little bit of money.

Summary: Works as designed, great little gadget
Comment: I have both a Sigma 50-500 (aka Bigma) and a Sigma 100-300 f/4. Prior to getting the latter, I was able to use the Bigma with my Kenko Pro 300 1.4X TC DG on my Nikon D70. However, the Kenko refuses to work with the 100-300 so I have to buy this Sigma TC which works extremely well with the 100-300. However, unlike the Kenko, I cannot retract the Bigma all the way with the Sigma TC which is why I only give the Sigma TC 4 stars.

The 100-300 f/4 focuses as fast with or without the TC and I don't seem to lose image quality with the Sigma TC either. The EXIF info also correctly shows 420 mm was used. [...].

Summary: Sigma 1.4x Teleconverter
Comment: Mating perfectly with the excellent Sigma 50-500mm lens, this teleconverter increases focal length. The downside is that it decreases aperture by 1+ stop, and you lose the autofocus capabilities of the lens.
