The following opinions have been automatically translated with Microsoft Translator. | Minolta MD Rokkor 50mm f/1.7 Pros: Durability Cons: Poor sharpness and reduced contrast to TA, chromatic aberrations Opinion: I wanted to try this 50mm, previously mounted on an old SLR Minolta, on my Canon 250D (APS-C) with a simple adapter; with the conversion it is comparable to an 80mm on FF. Despite the years (about 30) the lens has been preserved very well, apart from a few grains of dust, including rings. At full aperture the sharpness and contrast are extremely low (the effect may please, personally I do not appreciate), closing at f/2.8 the image quality improves greatly up to f/5.6. I would call the color rendering "neutral". I would have appreciated an intermediate shot, an f/2 for example, to enjoy a wide aperture more usable in standard situations. sent on May 06, 2022 |
 | Sigma 17-50mm f/2.8 EX DC OS HSM Pros: Sharpness, fixed aperture at f/2.8 Cons: AF "noisy" for videos, rings Opinion: I switched to the Sigma 17-50 after a year with the "classic" Canon 18-55 and the difference is noticeable, despite the good performance of the lens kit. The fixed aperture at f/2.8 is certainly its strong point and unlike other lenses, it offers excellent sharpness already at TA, which becomes excellent from f/4. Pleasant bokeh, considering the type of lens I would not have expected better. The construction is discreet, the consistency is perceived starting from the weight, adequate for the type of product, while I would have preferred a less contrasted zoom ring also because there is the 17mm manual lock that prevents involuntary extensions, questionable also the ring for the MAF that in addition to not allowing the full-time manual focus, rotates only 45 °, making precision adjustments difficult. The overall yield is excellent but at short focal lengths, in addition to the classic distortion, there is a slight loss of quality on the sides of the frame; on average, chromatic aberrations and stabilization. To conclude, the AF works rather well but in some cases, especially in unfavorable light conditions, it is not very precise; the HSM engine is not particularly noisy, however during video recording it becomes unbearable if you use internal microphones (in this sense the Canon STM, for example, are much better). Despite the flaws, it remains probably the best zoom for APS-C under € 300 and a decent upgrade compared to the lenses in the kit. sent on April 22, 2022 |
 | Canon EF-S 55-250mm f/4-5.6 IS STM Pros: Lightweight, silent AF, stabilization, versatile Cons: economic construction, loss of quality (especially sharpness) over 200mm Opinion: Taken as the first "super-zoom" for Canon APS-C, coupled with the classic 18-55 kit allows you to cover 90% of situations without spending a capital; suitable for those who do not have too many pretensions, this lens guarantees more than discreet performance in conditions of good brightness and with subjects not too far away. The sharpness is discreet, not exciting, even at TA, while there is always a bit of vignetting, instead the chromatic aberrations remain contained; performance drops above 200mm. Very good stabilization, af quite fast and accurate, average reliability. The construction entirely in plastic is not its strong point, on the other hand, thanks to the low weight, the 55-250 is excellent to take on the road and suffers very little from drift phenomena; good the two rings, "light" but not too much. Obviously it is not a bright lens, but on the economic range of Canon it is not better, if not pointing to the new and more expensive 70-300. Advised sent on April 11, 2022 |
 | Canon 250D Pros: Reduced size and weight, sensor, articulated display, live-view mode Cons: Few keys/rings, 9-point AF; in some ways, worse than the "old" 200D Opinion: I bought the 250D to enter the world of photography without too many pretensions, but with a body with good characteristics. The small size and weight make it one of the most compact SLRs ever and suitable for travel, at the same time, however, they make it a bit uncomfortable to grip (despite the good grip) with important optics that inevitably unbalance the weight forward. The build quality is discreet, there is no tropicalization; The 24mp APS-C sensor is the same as some higher-end models and is of good quality. Up to 1600 ISO the noise remains quite contained, above 3200 it becomes difficult to manage even in post. The camera gives the best of itself in live-view mode, in which you can take advantage of advanced functions and especially the Dual Pixel AF, always preferable to the obsolete 9-point optical viewfinder system and rather reliable even in video. The touch display is fully articulated and clearly visible even during the day. Like the latest Canon, this model is compatible with the Camera Connect app that allows you to quickly transfer photos / videos and use some functions remotely. The battery life is excellent using only the optical viewfinder and in normal conditions you can easily cover the day of use; otherwise, enabling the live-view and fiddling with the various settings will always need a spare battery. This Canon represents a good compromise between price and performance, however due to its limitations it remains a product that can only satisfy beginners or amateurs, despite the compatibility with the huge fleet of EF/EF-S optics. The "old" 200D, which I was able to use thanks to a friend, has extra keys on the left side, a richer mode dial, the AF illuminator (which on the 250D is "replaced" by the manually operated flash), a better feedback of the shutter button and the "central pin" on the upper slide, which enables support for third-party accessories. Despite the adoption of a newer processor, the Digic 8, which allows recording in 4K (with an important crop) and the Eye AF, the overall performance is almost identical to the model it replaces and from some points of view, as mentioned, it is a step backwards ... sent on March 02, 2022 |
