The following opinions have been automatically translated with Microsoft Translator. | Sigma 500mm f/4.5 EX DG HSM 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. sent on August 29, 2012 |
 | Sigma 180mm f/3.5 EX HSM Macro Pros: Extreme sharpness even seeds / duplicate, focal length, very low cost for the class of optics. Cons: Covering a little delicate discontinued. Opinion: And 'perspective razor sharp, to the point that I use with Sigma 1.4x TC mounted on always getting a 252mm crystal clear that I can shoot sure you do not drive out the people who rebuke and at an angle of the field that further blur the background, so pulling more on the subject. When used in areas other than the macro (where the more you use the manual focus), has an AF a bit slow despite limiter has, but to me that I use for the purpose for which it was born, (macro photography) , it is not a problem. Given that it is a series of "EX" (the series "Luxury" Sigma) and costs (or better than "cost") half homologous series "L" Canon, while producing virtually the same results, you do not understand really why Sigma have decided in the output of production, the dark mysteries of marketing. If you're lucky enough to find used but in good condition, it is "likely" to even an affable even better. Recommended! sent on October 01, 2011 |
 | Tokina AT-X Pro 11-16mm f/2.8 DX Pros: Sharpness, brightness, strength and construction Cons: Tendency to flare, focal length reduced. Opinion: When I bought this light I did so with the knowledge that it was not perfect optics, but I was more than certain that possessed the characteristics I was looking for. The greatest advantages available to this Tokina, are in my opinion the sharpness, really good and the minimum aperture of f/2.8 on the whole (short) hike. I love shooting at night and such an opening performance allows almost unique to a super wide angle like this, even indoors or at least dark. The sore point of this is in my opinion bell'obbiettivo resistance to flare, not great and the hike for some might be limiting. For me that initially I wanted even a fixed, certainly not was and at the same time is what contributes to the confere excellent sharpness that the lens has. Lately I have also purchased the 'Sigma 8-16, (another "piece of history", are a lover of extreme focal), but I decided to keep the Tokina also, due to its virtually unique features. sent on September 29, 2011 |
 | Sigma 150-500mm f/5-6.3 DG OS HSM Pros: Price / performance ratio, focal length, stabilizer 2-3 stop with POS Panning, collar with handle bag provided. Cons: Sharpness is not exceptional when using the maximum LF and TA, dim, weight, lack of a limiter for the AF. Opinion: Use this view for years and use it correctly pact has always done his "dirty work." Using "correct", especially if the maximum focal length, means close af/7.1 - f / 8, fill the frame (no crop), possibly use it to stand (but in my opinion this is true for all optical reach similar focal) even if the stabilizer does its job well. It 'a perspective that needs light, but used properly pays off with more than just good results. Of course it is not comparable to my Canon 400 L f/5.6, God forbid, but two things are very different and incomparable. Who wants to get closer to photo hunt "without getting hurt," with this perspective will not be disappointed, especially if you will use it as mentioned above, in order to derive maximum benefit. sent on September 26, 2011 |
 | Canon EF 400mm f/5.6 L USM Pros: All too extreme sharpness Opening (F/5.6), is also extremely fast AF, lightweight, compact, built-in hood, price / performance ratio. Cons: Lack of stabilizer (but it makes up for a short time), if semiduplicato lose AF on bodies not set "1". Opinion: This 400 series fixed "luxury", in my view, a truly unique price-performance ratio. Its extremely simple optical scheme enabling him to achieve extremely high performance in sharpness and speed of engagement of the subjects. Canon has never updated, despite both in production for years ... and I think they have their own good reasons. For my part I can say that it is a pleasure to use this light, the sharpness which also gives the possibility of some crop. And 'perspective particularly paid especially for shots of birds in flight, personally use both shed on that tripod with towel leafed with monopod. Used for the purpose for which it arises, in its price range in my opinion, simply has no rivals. sent on September 26, 2011 |
 | Canon 7D Pros: Hyper reactive machine, with functions and class performance. The double digicIV makes it as fast as any other APS-C. File extremely good (especially when combined with optical solving). Super configurable, very reminiscent of a small number "1". Excellent price / performance ratio. Cons: To give the best of optics requires solving (and expensive). Noise at high ISO this (but nothing tragic and in any case better than their predecessors APS-C in spite of the increase in resolution). Opinion: After 400D, 450D and 500D the jump was great, but having had the opportunity to work with a 1DMKIII often, I had a good measure of comparison and in this sense the 7D was a pleasant surprise. I must say that is a body that never lets you down, always ready, even in situations of acute stress. The noise at high ISO so much talked about, often vanish simply resizing step at Mpixel of the machines used in the comparison, or going to print, in any case it is better than any body has the predecessors. Sin'ora has never been a problem, even in prints with generous dimensions. The extreme personalization that is attached, may, however, lead to erroneous assessments. It 'important to be masters of the sophisticated AF system, which gives the best of optics "rank", as the sensor reaches easily the very dense "Diffraction limit" of the lenses cheaper. The widespread among users in these areas, is clear on the success of this body the excellent price / prestations, however, must be put into account the purchase of expensive optics for maximum benefit. In a future MKII I'd still have a lower noise at high ISO (already so still usable in many situations), a second slot for CF, fourth slot "C4" on gerahs prncipale and dynamic range still a little wider. Finally, all 19 AF points are cross already more than enough, but given the specialization of this body, I think it's also possible to do better, especially optimizing more contrast sensitivity of the center point. Machine is not recommended for beginners or those with little experience, needs a bit of study before reciprocate with great satisfaction. sent on July 18, 2011 |
