Advantages: Superb design, value for money and professional results.
Disadvantages: None

...Sigma EX 12-24mm F4.5-5,6 DG Nikon fit AF D. This a great wide-angle zoom lens offering professional performance, results and is a joy to use. It is suitable for both digital SLR's and 35mm Film cameras and focusing can be used manually or autofocus. This my first Sigma lens as I own only quality Nikon lenses so I was unsure at first about purchasing a brand and lens unknown to me. Any doubts or fears about quality were put to rest as soon as I took the lens out of it's box. It is as well crafted as any Nikon lens and a truly remarkable piece of design. It has an unusual appearance as instead of the usual glass flat surface lens it has a "bobble" or "ball" of glass which has a very alien look to it. I'm still not used to this and I feel that as it is sticking out so much that it may be a bit vulnerable to potential damage... Read review

Advantages: Good all-rounder lens for APS and full frame bodies
Disadvantages: Extending zoom body and some barrel distortion at wide

...Overview ------------- I bought this lens to replace a EF 28-135mm IS USM lens. Build Quality ------------------ Typical high build quality of Canon L series lenses. The 24-105 does feature an extending barrel at the outer end but it does not rotate so polarisers and the like can be used. The controls are firm and have a pretty good feel but compared to the EF 17-40 f4 L and the EF 70-200 f4 L IS, which have non-extending bodies, it does seem less solid and slick in operation. In bad weather and very dusty locations I do worry that moisture or dust may get in through the moving barrel seal but so far in my travels it hasn't. Compared to my old standard EF 28-135 IS, the 24-105 is obviously built better. Performance ------------------- This lens is now my default lens on my 5D body. It does for about 80% of my photos...

Advantages: Compact and excellent photos and videos
Disadvantages: Mute during filming of an action on the zoom + zoom too sensitive

...Main features of the digital camera SAMSUNG NV24HD (New Vision 24 High Definition): -- very compact and flat -- Ultra-wide angle 24mm: brilliant! -- Very good sensitivity and super video quality photos (nickel up to 400 ISO included) -- Stabilizer images (photos & videos) -- HD video sophisticated (H.264) with stereo sound! -- Screen AMOLED (Active Matrix Organic Light Emitting Diode) very accurate, very colorful, true in the colors and with a very wide angle of vision: fabulous, unique and unrivalled at the moment! -- Protective glass screen in polycarbonate hardened and anti-reflection (nothing to do with my old Canon PowerShot A70!) -- "Selection matrix" parameters (for me, much better than the "rose" traditional) -- Function "ACB" (dynamic control and automatic contrast… as the FX500) -- Shooting burst (as...
