In it's class of super telephoto lenses this is a great value for the cost. Photos are sharp and clear. I took the time to calibrate (AF) the lens to camera and found the lens right on the money w/o adjustment.

If you've been looking for a long telephoto lens for less than £1000, odds are you've been disappointed. Until now that is, as the new Tamron SP 150-600mm f/5-6.3 VC USD boasts an impressive zoom range and just sneaks in under the £1000 bracket.

Love it. Swapped for 100-400, which I loved, but added zoom makes this purchase a no brainer

Zoom range; Image quality; Value for money

Cannot think off any

In the same way that all little boys want to be astronauts, all budding photographers dream of long lenses. Right? Well, perhaps not all, but the super-long lens is surely on the wish list of many who have yet to realise that they won't actually need one.

I recently purchased this lens and used it almost exclusively during a stay of a week on an island photographing all manner of seabirds including the ubiquitous Puffin; for the price I paid the lens was outstanding producing sharp and detailed images sometimes at great range.

Durable; Great Features; Great Picture Quality; Simple Controls

I needed a telephoto lens for a pending holiday in the Highlands of Scotland, my camera is a Canon 7D. I had already bought a 2 times converter as I could not afford a dedicated Canon tele lens but wasn't satisfied with the quality or resolution.

The focus is faster than the other telephoto zooms I tested before buying. I am impressed with the quality of the hand-held shots even when extended to the full 600mm focal length. Low light doesn't seem to be challenge as I used the moon for some shots and got excellent results.

The Tamron SP 150-600mm f/5-6.3 Di VC USD would rate recommendation on the basis of its price alone, all other factors being equal. Its closest competitor is Sigma's 150-500mm f/5-6.3 APO DG OS HSM, which has a similar AF drive mechanism and optical stabilisation.

Used with Canon EOS 1D M4 and compared to Canon EF 300L F2.8 IS M2 with 2xTC M3. Tamron's actual max focal length is 580mm. At the max focal length pictures are lucking about 5% of sharpness against EF 300L F2.8 IS M2 with 2xTC M3 converter.

Easy to use

Pros:- reach light weight effective VC decent IQ price Cons:- Have to use f/8 to get decent sharpness at 600mm Not a replacement for 600mm f/4
