The following opinions have been automatically translated with Microsoft Translator. | Sigma 150-600mm f/5-6.3 DG OS HSM C Pros: Excellent overall Performance, taking into account the price. The ability to personalize through a dock is excellent. TWO Custom configurations selectable by selector. Very good Construction. Cons: In my opinion only the bracket too small. Opinion: I have this lens for two months now and I am very happy with the purchase. It was my first 600mm lens and I have to say that it wasn't all that easy at first. But slowly I'm taking my hand and recently gave me the first satisfactions. For its price I find it is excellent both as sharpness and as speed and accuracy of focus. The possibility of being able to modify the parameters, update the firmware and adjust the focus, through the dock was the thing that made me prefer it to the Tamron. I think that for third party objectives is a very important thing, to ensure compatibility with future camera bodies (to be seen, but for how long the updates will be released). I have done the calibration of the focus using the dock and, although already good immediately, is now much more accurate at every focal and distance. I Find that it is pretty sharp at all focal lengths and, at 600mm, I often click even at full aperture with good results. It comes with a beautiful rigid bag for transport and a shoulder strap to attach to the tripod bracket. A finesse the ring to be inserted in place of the tripod mount when you want to remove the latter. Perfectly Restores the aesthetics of the lens. The only flaw (albeit nothing that ') I find that is the tripod bracket too short. I obviated it with a longer Arca-Swiss sled and problem solved. A lens that I would like to fully recommend. UPDATE 22.04.2019 To Date I have this lens for 3 years now and I took about 17000 photos (I would say practically all birdlife). I fully Confirm the first impressions I wrote in 2016, shortly after having bought it. In October 2016, taking advantage of a small repair service, I asked them to let me adjust the autofocus. I came back perfect (no F/B obvious focus) with all the values of the dock-station zeroed (this way if you presented need I would have again all the range of adjustment available). I shoot almost always at full aperture and at distances between 3 and 15 meters and I have to say that the sharpness (for my needs) is very good at all focal. At greater distances, however, the quality falls. After three years of use, sometimes not too delicate, does not present problems if not a minimum of play (rotary) in the zoom (also present from new). After trying the various customization combinations of the selectors I prefer to use standard configuration which seemed to me the most accurate in terms of stabilization and speed of MAF. As a summary I can say that is a lens that I highly recommend to those who want to approach the birdlife. Removing the bracket reduces the weight and can also be used freehand, which is not just for those who practice itinerant hunting. sent on August 14, 2016 |
 | Canon A-1 Pros: high-level electronic (especially for the time). Reliability'. Robustness. Feeling (still and 'spectacular, use) Cons: Use in difficult manual does not bear the viewfinder aperture set (it indicates that suggested). Opinion: I own the A-1 for about twenty years, bought used in the middle '90s after gaining experience of my father (he also owned one, I buy' when it had just come out). A spectacular car, with all the automatic Av, Tv, Manual, exposure compensation in 1/3 increments. I used it with a lot of satisfaction until a few years ago when the mirror started to be slow in the pull (SOLVED - see update at end). rnL'unica thing I never liked and 'how' was designed function Manual: The machine, in fact, does not report targeted the selected aperture (lens), but only indicates what they would choose her. This forces you to take your eye from the viewfinder to make sure that you choose the aperture you set. But definitely it not 'born to be used in manual, as demonstrated by the fact that it was one of very few cars of the time to have both the functions Av and Tv.rnA aside the problem of the mirror (SOLVED - see update at the end) and the electronic shutter still work very well. Amazing considering it has more 'than 30 anni.rnrnUPDATE 06/25/2016: After you shoot it in hand for this review I came back the urge to see her work, so' I did some research on the net. I saw him slow mirror and 'a very common problem of this reflex and you can' solve even with the "do it yourself." I followed this tutorial clear: https://www.youtube.com/watch?v=6XYX7AF2yto and with immense joy the mirror and 'born again !!!! sent on June 22, 2016 |
