The Canon EF 50mm f/1.4 USM was released back in June 1993 sitting as an inexpensive option in-between the very costly (and now discontinued) EF 50mm f/1. USM L and also the cheapo EF 50mm f/1.8. On an APS-C DSLR the field-of-view resembles a 80mm full-frame equivalent. Concerning the ultra-large aperture the lens could be regarded like a portrait lens on APS-C but normally the scope isn’t restricted to that.
The 50mm f/1.4 regular lens is really a fantastic selection for each casual and expert photographers. The lens is outfitted with two high-refraction lens components and new Gaussian optics, which combine to get rid of astigmatism and suppress astigmatic distinction. Like a outcome, the lens obtains crisp pictures with small flare even in the optimum aperture. The lens’s f/1.4 speed, meanwhile, is ideal for available-light shooting. And like a bonus, this lens may be the only lens within the EF program.
The lens is just a little unusual within the worldwide Canon lens context – it functions a micro-USM AF drive such as full-time guide (FTM) override in one-shot AF mode. This really is, I believe, a very distinctive mixture. FTM is generally feasible having a ring-type USM drives only. The AF operation is very quick and silent but just a little even worse than ring-type USM lenses (for example e.g. the 85mm f/1.8 USM).<br> Guide focusing feels quite smooth and also the broad, rubberized manage ring adds towards the good impression right here. The general construct high quality is really good having a metal mount and an outer barrel created of great high quality plastics.
You will find definitely much better choices for any quick 50mm lens available, but apart from the Sigma 50mm F1.4 EX DG HSM theres truly not a lot obtainable for lest than a grand which has the image high quality of this lens. In all honesty the Sigma is constructed a little bit much better and is really a little bit sharper broad open, but using the slight cost distinction (about $100) and also the ensure that the autofocus ai will usually be right, I will go using the Canon and take the slightly less expensive constructed and minor loss of edge sharpness in between 1.4 and 2.8.
The EF 50mm f/1.4 USM showed an nearly flawless overall performance throughout the lab- and field-tests each in terms of optical and mechanical high quality. If I needed to list several bad points it will be vignetting and reduced contrast at f/1.4. So if you are searching for a lens in this class the EF 50mm f/1.4 USM is really a excellent choice.
