The following opinions have been automatically translated with Microsoft Translator. | Tamron SP 150-600mm f/5-6.3 Di VC USD G2 Pros: good optical quality - overall weight still acceptable for those who shoot freehand in slit support and who do not want optics split back - stabilizer present and useful of course as needed - price Cons: af discrete performance (not at the levels of optics usm canon to understand us) but still does overall its duty - possible problems of f---b focus Opinion: So, I write after a year of use basically in sheds and always TO MANO FREE with simple support to the slit to unload the weight. So optics never used on TREPPIEDE ! The machine body on which I shoot is the canon 80d. As soon as the optics arrived I sent it to have it calibrated with the body in a store, because I noticed some problems of f---ing focus. Anyway what to say, the optics is already discreetly sharp at 600mm f 6.3, if you can close a little much better of course. For the rest it always applies the rule to try to expose the best possible during the shooting and to make a simple but well-groomed postproduction. I come from the canon 400 5.6, very light optics, qualitatively superb and also excellent as autofocus performance. Obviously in terms of pure visual quality this g2 tamron is a little below, but believe me it defends itself really well considering the range of excursion. The autofocus on the whole gets quite well, the flaw that you feel a little more is that I see a little difficulty in keeping the subject hooked (the maf tends to detach and then hang up, generating a number of shots not well in focus). This could partly come from the fact that I use freehand optics, so to test the nine you should try the tripod optics to avoid the shaking and "instability" due to freehand use. Personally I'm quite picky, my bird photos have to have a good detail, and if you browse through my galleries I think you can get an idea. As value for money, I find the lens as a whole ! Basically I made the change because I needed the 600mm. On the other hand, using the 400 5.6 and then always cropping a mess does not make sense..... moral of the fairy tale for what is my use I enjoy more now, although at the level of performance af I lost a little compared to before. Anyway The photos get nice even without fixed lens and ff believe me, it's all about having a little handle ! I often see people with "monsters" of optics in their hands, shooting in uncomfortable positions and without a real conspection of what they have in their hands. Learn about your needs and make sensible purchases !!! sent on August 23, 2019 |
 | Canon EF-S 15-85mm f/3.5-5.6 IS USM Pros: large total of good optical quality: wonderful focal range: good construction: reasonable weight: stabilized: usm Cons: cartoon a bit but nothing that can not be resolved in a PP is quite dark as optics, reaching 5.6 at full zoom: at least the hood could include the canon-tirchioni. : You tropical conditions (I do not blame for charity but it is fair puntualizzarlo) Opinion: In my opinion, if you are willing to give up the brightness of a lens by virtue of a range of focal lengths idyllic associated with good optical quality, this is a lens with the cons c ..... on APSC. l 'autofocus is very very fast; hardly be hooked from the camera body, unless at that time did not have the need for bokeh and blur given by larger openings sent on March 08, 2014 |
 | Sigma 18-35mm f/1.8 DC HSM Art Pros: optical quality at very high levels: rnnitido already in 1.8: rncostruzione: Ultrasonic rnautofocus: rnseppur small, it has a little excursion to extend versatility: rnzoom without internal elongation physical optics: RN9 blades (excellent bokeh). Cons: is not exactly light (inevitably): rnnon has stabilized, but of course to stay within a certain price limit is natural rnnon is weather sealed, but to stay within a certain price comprensibile.rnvignetta is a bit wide but in its use nothing in particular Opinion: the important thing is to be aware of what you acquista.non will never beat as a focal range of 15-85 for example, but if you are looking for a medium focal high optical quality with the addition of 1.8 brightness well, you do not have doubts about ' acquisto.a quality if the plays quietly with cinquantino fixed to give you an idea, plus it is already usable by all apertura.tanta stuff sent on March 07, 2014 |
