Maybe you can help.
I've been bending my mind over the 400mm focal length for quite some time but can't make up my mind. Too many options but none that really stand out. Here are some of my considerations, all for full frame use:
I'd like something better than my 100-400L that I can shoot hand held.
I don't require a zoom and use 400mm mostly for motorsports or animals in a zoo environment.
A 400mm prime would be nice especially if I can use my 1.4x II to go to 560mm occasionally.
I don't want to break the bank or my back. I'd like to keep the weight of the lens under 2.5 kg if possible, investment below 5000 Euro's.
I previously owned the Sigma 150-500 OS, but couldn't live with the handling (focus ring in the wrong place) and the performance at the long end was only so-so. That lens also felt really heavy but looking at the figures I think the weight distribution was more to blame than the actual weight (front heavy).
I know some of you use the new Tamron 150-600 and the resolution looks good at 400mm but it reminds me too much of the Sigma, and I no longer want any lenses that have a maximum aperture of f/6.3.
- The 400mm f/5.6 has no IS.
- The 400mm f/2.8 I or II is too heavy and big for one. The cost is a killer too.
- The 400DO has a mixed reputation. I know of a shop that has a used one, with one year warranty for €3999. The shop is not exactly around the corner but I'm actually really tempted by this one...
- The 300mm f/2.8II is a stretch, and I'd have to use it with a 1.4x II or buy a 1.4x III making the stretch even longer.
- The 300mm f/4 IS looks great but less so with a 1.4x
- 70-200 f/2.8II with a 2x TC? Maybe not.
What else am I missing? What would you recommend?
