I bought this lens because it offered 600mm over the 400mm of my canon lens that had gone in for repairs. I read numerous reviews which praised the lens for its value for money. I took the lens to Lake Mungo National Park where I had 2 days bright sunshine and a day of overcast skies and rain.

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

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.

The 150-600mm telezoom lens has come into its own in recent years. Tamron came to the party first, with its affordable SP 150-600mm f/5-6.3 Di VC USD ($1,069.00 at Amazon) , but was quickly joined by Sigma, which released consumer and pro-grade versions of its 150-600mm simultaneously. The Tamron SP 150-600mm f/5-6.3 Di VC USD G2 ($1,399) isn't a replacement for its first take. Instead it's a pricier, sturdier, more refined optic, complete with an all-weather build and incredible image stabilization system. We're sticking with the Sigma 150-600mm DG HSM Contemporary ($1,069.00 at Amazon) as our Editors' Choice, but if your shooting needs call for work in heavy rain, consider the Tamron G2 as an alternative. Design Like other 150-600mm designs, the Tamron G2 ($1,069.00 at Amazon) is a big lens that extends when zoomed beyond the 150mm point. It measures 10.2 by 4.3 inches (HD) and weighs 4.4 pounds. It's in line with the Sigma 150-600mm Contemporary (10.2 by 4.1 inches, 4.3 pounds)...

The Tamron SP 150-600mm F/5-6.3 Di VC USD G2 lens has some edge sharpness issues, but is an overall solid performer, especially when paired with an APS-C SLR.

Strong sharpness through most of range; Excellent stabilization system; Quick autofocus; Lockable zoom mechanism; Rotating tripod collar; Integrated Arca-Swiss foot; Weather-sealed design; Available for Canon, Nikon, and Sony SLRs

Weak edge performance at wide and telephoto extremes; Teleconverter use limits autofocus operation

When Tamron introduced the first generation of the 150-600mm f/5-6.3 super telephoto lens, they were innovators in the third-party market. Never before had the barrier to entry for photography requiring a super telephoto lens been so low.

The Tamron SP 150-600mm f/5-6.3 Di VC USD ($1,069) is an intriguing lens for capturing nature, outdoor sports, and other distant action. It's compatible with full-frame cameras , although many shooters are likely to pair it with an APS-C body to enjoy some added telephoto reach.

Long telephoto reach; Optical stabilization; Strong center sharpness; Attractive price point; Zoom locking mechanism; Includes tripod collar and hood; Available for multiple systems

Pincushion distortion throughout range; Focus can be a little slow; Some blurriness at edges unless stopped down

I really like this lens. It is very sharp and quite fast focusing. It is quite heavy but I find the weight helps to steady it when shooting without a tripod.

I got this product around a year back for the price one pay when you compare it with Canon or Nikon its magnificent. It really does not work in low light but and its bit heavy when you have to wait for your subject.. I captured some great shot on with these lens and I am happy with it.

Wildlife and sports photographers immediately recognize the attractiveness of the telephoto zoom focal length range of this lens. Lenses that include 150mm in their focal length range are plentiful (and very useful), but no big brand name zoom lenses as of this review date include 600mm (other than...

Tamron's new ultra-zoom lens, the SP 150-600MM F/5-6.3 Di VC USD, is a large and powerful zoom lens for anyone that is looking to get up close and personal with their subjects. This large lens can be used with either Full-Frame or APS-C sized image sensors, although with an APS-C sensor you are...

Amazing zoom range; perfect for shooting from a distance; Vibration Correction adds up to 4 stops of correction when shooting handheld; Although large; it is compact for this class of lens; Smooth; easy rotating rings for zoom and focus; Weather-sealed for shooting in all conditions; Affordable...

Problems with the AF system on the cameras when using this lens; Slight amount of give when the lens is attached to a camera body
