Absolutely amazing lens, very impressed by the crystal clarity of images it produces. Other reviews attest to this. Despite mixed pixel peeper opinions of the 2X teleconverter I decided to give the combination a try, who wouldn't want to DOUBLE the reach of this amazing glass? My experience using an A7RII body, a sturdy tripod and a wired shutter release has proven very positive, blown away by the extreme reach and crispness this combo can produce. Seems to me some of the negative sentiment around the 2X teleconverter may come from people expecting too much, yes the reach is doubled but it's not going to turn your camera into the hubble telescope(!), limitations remain how far away a subject can be while retaining clarity. Stopping the aperture down a few steps and doing everything possible to eliminate any source of movement or vibration makes a significant difference.

Not many would say this was the first major lense they’d purchased but I knew I had to get my hands on a 200-600 after I got my Sony a7iii. I had originally rented a 70-300 Tamron to see if I liked it and used it for my first wildlife outing. I was happy with the results but it just made my hungry for the 200-600. I did some heavy thinking and thought, why the hell not. I’ve used this lense for Sunrise, and wildlife photos and have NOT been let down. The internal zoom is probably my favorite feature as it prevents dust and moisture from getting into the lense unlike Sigma or other 3rd party lenses.

If you’re looking for an incredible lense for wild life or nature, look no further. It’s worth the price and you won’t be let down by the quality.

I found this lens to perform exceptionally well for sport. It worked up to expectations as opposed to adapted zoom lenses. I previously had in my workflow for sideline football, the canon 300 f2.8 with the MC-11 adapter. While that lens produced sharp images, the consistency was extremely lacking due to the lack of ability to track the subject. Therefore I decided to change to the Sony F5.6-6.3 200-600mm with the understanding that I may have to stress the iso a lot more than I like to do in low light high school football situations on friday night. I've paired the lens with the Sony a7riii. What i loss in the ability to blow out the background consistently, I gained in not losing as many shots as due to the tracking ability.

I find this to be a strong consideration in the sporting space particularly if you will be able to shoot a lot more sports in the daytime or under great lighting.

What can I say but wow! Using this full frame lens on a NEX-7 with cropped sensor I get equivalent 300 - 900mm focal length. Caught this heron at the moment of touchdown at 500mm focal length on 1/1000th and 1600 ISO in low morning light at about 150 yards. This was my first morning shooting with the new lens. It exceeded my expectations by leaps and bounds.

Absolutely love it from the moment I used it. Auto focus is amazingly fast for a huge telephoto lens. Tripod or no tripod & the overall performance is just amazing. The photo posted is just one example of how sharp the image quality is. Would highly recommend this lens to anyone wanting that extra reach. A++

It exceeded my expectation !

Arrived in a well package box. I was worried that the glass will get damaged but to m surprise, it arrived in great condition.
