The following opinions have been automatically translated with Microsoft Translator. | Sigma USB Dock Pros: Very useful for "revitalizing" Sigma lenses with back or front focus problems Cons: Maybe the price Opinion: I bought the Sigma dock to solve a front focus problem on the 30mm f1.4 ART lens. I had noticed that the focus was always a few inches closer than expected. This phenomenon is extremely annoying especially on a lens that has among its main characteristics that of an opening so wide and therefore a very tight PDC and to be adjusted with millimetric precision. Well, the USB dock is very easy to use and with an hour of work I solved the problem of front focus, and now I find a lens that focuses perfectly at any distance of use. To test the corrections reliably I followed this simple and clear tutorial: https://www.youtube.com/watch?v=2OmxtddLfPM&t=97s It happens at the end of the fair I found myself applying corrections very similar to those found by the author of the Video, so maybe the front focus of this lens is a fairly common flaw. of cons, as the user says before me, the price of 39 euros to which this item is slightly exaggerated, since it is a simple interface between lens and PC. But in any case, it is a recommended object to those who possess recent Sigma optics. sent on November 29, 2018 |
 | Canon 77D Pros: User agility, Adjustable touch display, optimum autofocus, general impression of reliability and professionalism, dual display, double ring Cons: Not detected Opinion: I bought the 77d to enter the world of SLR after years of photographic hobby spent with compact and bridge superzoom of various levels. I can not then make comparisons with other machines being my first reflex, but as a newcomer to this world I can say that the 77d is giving me the way to learn to photograph in a loose and gradual at the same time allowing me to practice the notions by way Most advanced learned during courses and/or self-taught experiences. I have never used automatic modes, I generally shoot in aperture priority or in manual and in RAW format, but the range of scenes and shutter options is very wide for those who want to use them. In General The camera gives me an impression of professionalism and reliability while not being among the top of the range. Some goodies are really useful, like the adjustable touch display and the small display on the top right that shows the most necessary information (ISO-diaphragm-time-shots remaining-etc.). Even the double ring is a trick that allows you to use manual mode and to perform many operations in a quicker and more intuitive than the classic four cursors high-low-left-right. In short, I think that the 77d is a model suitable for those who want to look at the APSC Reflex World in a semi-professional way and without having the remorse of having bought an insufficient equipment, in other words, I think that hardly anyone will take a Photo with this machine and then say "if I had another model would be better". sent on November 29, 2018 |
