got the Canon 50mm 1.4 because I couldn't get any further with normal zooms. I previously had the 24-105mm F/4 and then switched to the 24-70mm 2.8 due to the poor light output. In the long run, that's not enough for me either. I missed the minimum depth of field and also the light intensity on the Canon 7D. Despite the relatively high light intensity of 2.8, I couldn't offer that. I did a lot of research and came across the Canon 50mm lenses. There were 3 variants. 50mm 1.8, 50mm 1.4 USM and 50mm 1.2L. I decided on the 50mm 1.8 because of the good reviews and got it straight away. After trying it I was a little disappointed. The processing and the speed of the lens were not really right. I didn't buy the 50mm 1.2L because I think it's quite expensive for a hobby. Although I wasn't sure if the quality of the lens justified the almost 4 times the price. That's why I took a look at the 1.4er and ordered it directly. Processing: The delivery was quick as always and it was time to unpack. As soon as I picked up the lens, I knew right away. It was different from the 1.8. It was more robust and stable, although some of the materials stayed the same. Unlike the 1.8, the 1.4 had a metal bayonet. The processing alone is worth the money. Image quality: The focal length on the Canon 7D is 80mm according to the 35mm format and is already a light telephoto. Nevertheless, one has hardly any difficulties to find motives. What you immediately notice in the first picture with an open aperture is the beautiful bokeh. That was a WOW effect at that moment. That wasn't so pronounced with the 1.8. The bokeh was almost round. So I thought to myself, what would that look like with a full-frame camera and a 1.2 if it's really nice. The light intensity is just phenomenal. So far I had never had a lens that was really that bright. You can still shoot handheld in the evening and still get decent pictures at the same time. With an open aperture, the lens has small problems. It could happen that not the whole object is in focus. But that only happens when you open the aperture fully. From f/4 it starts to get really sharp. Some report vignetting. But I can't really confirm that because of the CROP. Another important reason to buy it was the auto focus. The autofocus on the 1.4 was far faster than the 1.8, but it doesn't quite match the 24-70mm 2.8L. As I have learned from other reviews, it is a micro USM and not a ring USM which would be even faster. Conclusion: Simply a very great lens. The 50mm 1.4 is slowly becoming my favorite lens. The light intensity is simply indescribable for the price.
