Best telephoto lens for the sigma fp?

The Sigma fp is a full-frame body, so for telephoto you want lenses that frame the long end at full size. From its catalogue page, these are the strongest options for reach:

• Sigma 300-600mm f/4 DG OS Sports is the serious choice for distant wildlife and sport, and it is the only one here that stays bright at the long end.
• Sigma 60-600mm f/4.5-6.3 DG DN OS Sports covers almost everything from standard to very long in one zoom, which suits a small body.
• Panasonic Lumix S Pro 70-200mm f/2.8 OIS is the one for portraits, events and anything in low light, where a fast aperture matters more than reach.

The fp has no in-body stabilisation, so pick a stabilised lens like these for slow shutter speeds. Full-frame telephotos are big and heavy, as the sensor sizes guide explains, so be realistic about what you will carry. For more on matching lenses to subjects, see wildlife and sport.
