Pros: Especially a price yet "human" before jumping "into hyperspace" of the kingdom of "super-toed" (Canon), excellent sharpness, fast AF, weight (manageable if you wish, freehand) and portability (the generous handle of which is with, it is even better even than those available in the "originals"). Great a successful union with the TC Kenko 1.4X DGX PRO300, with which you can keep the AF with good performance on machines with central point from f/5.6 (ie bodies "NOT series 1" which normally would be lost instead) . In the DG version are also been further reduced the AC and the finish is changed, now much stronger and style (actually different from the one shown in the image used for this review), it is easier to "matt black", some the kind of "Neroni" Nikon.
Cons: Although in my case would be totally useless, the stabilizer may improve performance when using free-hand (without using stand still, in my opinion is for short sessions, as always limited by the optics more than 3Kg those the camera body). Personally I find it ideal to use in tandem with stand fitted with head Rocker (I use it with satisfaction the Gimball TRIOPO DG-3), but if more flexibility is also a good monopod with ball head is just fine.
Opinion: After several months spent in vain to look for a 500 f/4.5 (both Sigma Canon) and thanks to an excellent offer of an online retailer particularly convenient, in the spring I decided to purchase the new version of "DG" of the 500 f/4.5 EX HSM Sigma. I am satisfied, from all points of view, despite the limitations inherent in the product ... obviously seen cost and maximum aperture, it is not (... and even aspires to be), a Canon 500 L f / 4 IS. Unlike other Sigma lenses I had, my version of "DG" did not need to say any micro-fine adjustment of AF on 7D ... is perfect as it is, it is smooth multiplied. Moreover, the diameter of a little more than 12cm of the lens forntale (which among other is the same diameter then the "Trecentone Canon effedueotto") allows the easy passage through the "joints" of huts fixed without too many worries. Pleasant and useful the possibility of being able also to have, thanks to TC1.4X Kenko (already cited in the "PRO" of review), of a 700mm f/6.3 around Rispect with AF still useful for chases birds in flight and excellent sharpness, (although as often happens in these cases, the maximum yield is reached diaframmandolo of c.ca 1 stop). Speaking of the market, in my opinion, having now in production with a view like this (also new and updated versions such as "DG"), Sigma has cleverly filled a void in this segment of the market left by Canon when it decided tolgiere production of its 500 f/4.5 (now unobtainable as well as used, for some time now even without spares). I personally do not agree with certain business decisions and I'm happy that Sigma has decided to remedy the situation so well ... when in fact, regardless of my positive experience, I know of users disappointed by this light, the rest of the testiomonia also difficltà to find such versions used. |
