Canon EF 800mm f/4L IS USM?

That would be a spectacular lens, however, IMO you'd be looking at closer to $30k. Compare with the $26,000 "sigzilla" 200-500 f/2.8 which would actually have a slightly smaller entrance pupil than a hypothetical 800 f/4 (177 vs 200mm). I acknowledge that the Sigma is a zoom, but I still can't imagine a comparable Canon lens retailing for less.

Would be fun for astrophotography, though!

Granted, it would probably cost close to $18k, but since such lenses are often mounted on tripods would the weight actually be a factor?

I think this would be an awesome lens.

I could see an 800mm f/4 DO IS being a possibility.

It would need to be 4.5kg or lighter and $17k or cheaper. Was looking for lens thread for the 800mm so I just end up replying to this
