10 out of 10 points and recommended by SteveRemy (2 reviews)Sharp and crisp Loss of F Stop not noticeableFocus response a little slow (for still photography so far) but will experiment further with sports shooting
I purchased the Sigma 15-600mm Sports lens and it came with the 1.4x Converter. I struggled with the 150-600mm in keeping it steady on the monopod photographing an Australian rules football match (AFL) and the result was good but less than impressive (partly due to the photographer and the weight of the lens). I've been using the Nikon 200-500mm for photographing local AFL football games with great results but needed the extra focal length to cover the large football ground which is why I bought Sigma 150-600mm F5-6.3 Sports. Disappointed with my photographic efforts with the Sigma, I tried experimenting with the Sigma 1.4x converter when I got home with the Nikon 200-500mm F5-6.3 and the results were mind blowing. With the relatively lightweight Nikon 200-500mm and the Sigma 1.4x converter, I get a 280-700mm focal range and the images are clean and crisp with my Nikon D5. I would like to share some of the images taken if Imaging Resource allows me to do so.reviewed April 10th, 2022 (purchased for $274)
