Taken at Tunnel View in Yosemite on Friday, February 23rd. The light breaking through clouds lit up this peak in a pleasing way.

I received my Sigma 150-600 mm lens yesterday. I've wanted to get one since it was first announced but my health issues made me reluctant to spend the money. I finally caved in and bought it. Today I'll be trying it out. Excited about that prospect. I have one question that someone on here may have the answer to. The instructions say that only the Sigma 1.4 teleconverter can be used with the lens. I have a Kenko C-AF 1.5X and a Tamron-F AF 1.4 teleconverters. If I try either of them with the new lens, is there risk of damage of some kind to the new lens?


Was that using the normal PDAf system or Liveview? Also are those converters you used it with reporting or non reporting? I would consider trying to pick up a Kenko to use with my 50D. It shouldn't really support PDAF since the 50D doesn't have ƒ/8 capable AF. Since the focal ratio limit on AF is caused by limits imposed by the width of the aperture, and not really by the brightness or contrast of the subject getting functioning AF is quite surprising.

Since I often need a 1.5× crop even at 600mm finding the lens might support a similar sized TC would be great.

I have one of the Kenko Teleplus 1.4x extenders which causes an error to be reported when shooting through the viewfinder of my 80D, however it works great in Live View on the 80D or especially on my M6. That's actually one of the main reasons I got the EVF for my M6 was to be able to use the teleconverter with the Sigma 150-600 C.
