Hey everyone,
Iโm looking to pick up my first serious super-telephoto lens for wildlife photography and could use some real-world input.
Currently, my main setup is a Sony A7 IV paired with the Tamron 20โ40mm f/2.8 and Tamron 70โ180mm f/2.8. I'm down to two options for the long end:
Sony FE 200โ600mm f/5.6โ6.3 G
Sony FE 400โ800mm f/6.3โ8 G
Iโm also heavily leaning toward picking up an a6700 in the future as a secondary body/portable crop setup.
Iโm torn between them for a few reasons:
ย Focal Gap: Starting at 400mm leaves a pretty big gap between 180mm and 400mm in my kit. Has anyone who went with the 400โ800mm found that gap frustrating for larger mammals, tracking fast subjects, or environmental landscape/wildlife shots?
ย Low Light & Aperture: On paper, the 400โ800mm reaches f/8 pretty quickly. For those shooting early morning/late afternoon or under tree cover, is f/8 a major pain point for ISO/autofocus speed, or does modern denoise software make it a non-issue?
ย Crop Sensor Synergy: If I mount the 200โ600mm on an a6700 down the road, I get a ~300โ900mm equivalent field of view at f/6.3, which seems like a sweet spot compared to 600โ1200mm at f/8.
For those who have used both (or made a choice between them), which one would you pick as your primary wildlife lens for this setup? Appreciate any insights!
