SIGMA 50-500mm f/4-6.3 APO EX DG HSM Telephoto Zoom Lens - for Canon

Good quality photos

Heavy

It is easy to use though a tad heavy if your useing hand held. Wondering if I would have been better with a lighter lense

Heavy and struggles to focus at times

Good build quality

Slow aperture

Light enough to use hand held for a few hours. Good focal range Good image quality

Teleconverters are manual focus only - not good for birds in flight

Does exactly what the manufacturer and state it does. Other than being a bit heavy- a fraction of the Canon price but similar quality photo's

Bit heavy but don't let that put you off!

Superb image quality and solid build

Good zoom range and this is why I purchased it. Quiet focus system which surprised me. So far very good and no problems. Not disappointed.

Very heavy so plan ahead when taking it out. A good tripod required. Stabilizer wanders a bit in video so found it best turned off when on the tripod.

Sharp images, quick focus

very heavy around 2 kilos

Ease of use

Not found one yet

This lens is brilliant through its whole range. I was surprised how quick i learned to use this hand held. Good fast autofocus and extremely good image stabilization as proved taking photos of Aircraft in 50 knot winds. Have found lens also great for...

Heavy weight takes a couple of days to get used to.
