New Sony 300mm f2.8GM with TC's

My main interest is wildlife, birds in particular (both static and BIF). A 300m is obviously not really the thing for BIF, but I’m really quite tempted by the thought of a 600mm f/5.6 that’s this lightweight — I do sometimes hike a fair distance. And Mark Galer’s review and images (albeit processed) seem quite promising.

Thanks!

(PS. I’ve pretty much decided against switching to Nikon, so please don’t mention the 600PF … But, for what it’s worth, my tentative answer to @ChrisMak@@ ‘s question is: yes, I think Sony have done exactly that! )


The AF should be faster as the 300 is fitted with dual XD motors the same kind that is used in 600 f/4GM. The 2-6 uses lower cost linear motors. This will impact the initial AF acquisition speed. The tracking performance is mostly function of the camera and will be similar the prime combo has 1/3 stop faster aperture but that shouldn’t have much impact on the A1.

Sharpness is the main factor, it needs to be clearly sharper with the 2X than the zoom (which isn’t bad itself) to justify the price for BIF. I am quite happy with the 2X on my 600 GM and I hope it is similar or better with the 300.

300mm is too short for general BIF so it will be mostly glued to the 2X for this application unless shooting large birds at close range.

Hope to receive one of these early next year and test it out

I DO wish Sony had more high-end telephoto options like Nikon does. 600 f/5.6 PF/DO would be a nice compliment to the 600 f/4 GM. even a 400 f/4 would be great as it will extend to 800 f/8.... 300 f/2.8 is the "least" optimal of the fast primes for general BIF (special circumstances aside) but it is better than nothing ... especially when price is "relatively" reasonable these days


A 400mm f4GM would be a great option. I used the Canon 400DOII with both extenders.
But that is all in the distant future, the 300GM is here and incredibly light.

But yes, the 2xTC would be glued to it, so it all depends on the performance with the 2x. Bokeh especially will be a deciding factor, next to resolution, I have no real doubts about AF on the A1.

I think I will get the 300GM though, as I expect it to be the only way to get to 600mm f5.6 at around 1,6kg for a long time to come.
