I am taking a trip the first weekend of December to Conowingo damn and my spouse is coming and will want to shoot. I plan on shooting my 600GM with a 1.4TC if needed and the second set up I have an option of either a 400GM with a 1.4TC or if needing the 800mm range with a 2x TC.
I hadn't tested the IQ with the 400GM with 2x TC vs the 200-600 with a 1.4TC so I figured I would shoot out my front door real quick and see what happens.
I shot the 400GM with the 2x TC wide open at F5.6 and made no Lightroom adjustments but I ran it through Topaz Sharpen at 50% to see what it would look like.
Here is the 400GM with no sharpening:
Here is the 400GM with Sharpen applied:
Here is the 200-600 with the 1.4TC at 600mm so an effective 840mm. Also shot wide open now at f9. The first image has no processing and no sharpening just like I did with the 400GM and the second image is processed only using Topaz Sharpen with the same settings as the 400GM.
Here is the 200-600 with no processing:
Here is the 200-600 with sharpening:
What do you all think? I would prefer the f5.6 over f9 however the flexibility to zoom might help them out vs a prime. I haven't tested to see which one will focus faster but I suspect it is close enough to not matter.
PS I didn't compare the 400GM with 1.4TC vs the 200-600 with no TC as they are both sharp.
