![]() | Tamron SP 17-50mm F/2.8 XR Di II VC LD Pros: Best price / performance ratio; Out of focus Cons: Some re-focus sull'AF; Quality mounting Opinion: I bought this to replace a Canon 15-85 lens which I no longer liked the performance in low light nor the quality of sfuocato.rnDa this point of view the Tamron was a net gain, aperture f2.8 is indeed a solution the shots in low light and pleasure to have shallow depth of field when I do portraits and first piani.rnrnQuando I went from Canon Tamron at the first feeling was not positiva.rnIl Tamron is plasticky and hard when you zoom in and switches AF and the stabilizer are tough. The look is not bad but in general the idea of ??most Canon qualità.rnUna when assembled things do not improve. Compared all'USM Canon AF Tamron is a return to origini.rnIl motor is felt, it is slower and much more serious every now and then does a complete re-focus before attaching the soggetto.rnrnScattando however, start to come out out pregi.rnIl diaphragm is obviously a gain than before and the quality & agravand; images is ottima.rnLe photos are consistently sharp, the colors a hot wire, and just a bit of vignetting on the corners but not stona.rnA 17mm distortion is quite more pronounced than on the Canon (at 15mm) and how aberrations we compared them to Canon.rnL 'AF makes noise, but I do not care and even the slowness, for the kind of photos I take but also for the intended use overall objective, it is not a problem; in'oltre , and not cheap, the AF is as precise as that of Canon.rnPer Fortunately, with a little 'practice, you can prevent re-focus but remain the only real drawback because sometimes you lose some shots " on the fly ". rnLo stabilizer works as well as that of the Canon with the only difference that in this case too is some audible hum ... boh.rnrnIn general'm happy to have replaced the Canon with Tamron but more looking at the pictures that produced when scatto.rnNe recommend buying but could definitely spend the Canon 17-55 would be the best scelta.rnrnSeTamron AF motor put their ultrasound might not have even rivals costing 100 € more. sent on July 11, 2013 |
![]() | Canon EF 50mm f/1.8 II Pros: All, considering the price Cons: None, considering the price Opinion: The fact that costs € 90 again turns any flaw into an advantage, I mean. It 's all plastic, but also weighs very little. The 5 lamellae are few to a great bokeh, but is not the "pannosità" of a bokeh to make a beautiful picture. The focus is not comparable to a USM, but my copy is always accurate and fast enough for a view portraits. The focus ring is not at all practical to use .... and this is just a defect. The 50mm could be too many on APS-C ... it depends on the photographer. In addition, the photo quality is very good, it is quite clear already at f1.8 (or at least it is my copy) and is bright enough to resolve difficult situations. I mean, did others fixed with the same quality and the same price 50ino'd take them all. sent on April 12, 2012 |
![]() | Canon EF-S 15-85mm f/3.5-5.6 IS USM Pros: Fast AF, build quality, stabilizer, all-in-one. Cons: Cost, diameter filters, brightness is not record-breaking, I'll sell it when I pass in full size. Opinion: I bought this lens kit with the Canon 550D and use "family vacation" is an all-in-one. A 15mm, which are then 24, is great for indoor photos and landscapes while at 85mm, which are then 136, is a medium / canvas that allows you to take pictures appreciable children running and amateur sporting events. The stabilizer allows you to shoot safely at night inside a house without using the flash (but is always handy) and the AF is just perfect. The 15-85 focheggia without hesitation in a few seconds and compared to many lenses of the same category (even non-Canon) looks like a series L. The notes have a negative depth of field always a little too wide for portraits (and in fact soon buy a Canon 85mm 1.8 fixed) and the diameter of the filters (72mm!!) Forces us to spend a lot of pennies for a polarizer or ND or close-up of quality (also the famous "welder's glass" is too small). If this "muzzle" Canon was able to make a fixed f4 lens would be a 10 on APS-C. sent on October 07, 2011 |
