Bad weather. So no easy startest of the new RF50/1.8. But here is an an extreme lower right corner comparison of the RF50/1.8 and the RF50/1.2L - both with all corrections switched off.The X-mas lights provides us with helpful pointsources to check for the point spread function of the two...

Both body and lens update worked fine and as promised. Guess the bug functional update will come later as mentioned in several interviews. Like the continuous silent shutter. Exactly what I need for theater/concert/church where the sharpest pic out of a series iis much easier to select now ...

Mine is also shipping from Germany to Austria ... let's see ... :)

I have it and its the same as for the rf lenses. The list of functions available for dials is found on page 560 of the advanced user guide ...

It really differs a lot from 14 - 135mm. ALL are used a lot at infinity and far away in typical landscape and nightscape pics.. The 50, 85 and 135 are used also at typical half portrait and face portrait distances. The 14 and 20mm in club and music environments. For my 5d3 and 7d2 I had...

Did you use the ef 50/1.2L or the horrible ef 50/1.4? Both are very unreliable lenses. I ownwed both. The SA 50/1.4 plays in a different league. I am sorry for you bad experience for you bad copy but have it replaced or repared is the way to go then ... Now with the eos R its even better. My...

You saw my list of lenses (only the 35mm had to be replaced) and I know of many others that have great results (the Art series is a huge success) . Many AF issues relate to the fact that users are not experienced with highly opened lenses and/or are using them without MFA on body or via dock...

Which AF problems? I have the 14/1.8, 20,/1.4, 35/1.4, 50/1.4, 85/1.4 and 135/1.8 Art lenses (and soon the 28/1.4) and they work perfectly on my eos R, 7d2 and 5d3 cameras. All with the most recent firmware ... Its a great system. On the R it is even better.

Because this lens does not exist from canon and because it seems to have stellar performance (as most of the other art lenses).

The good news: it will come soon, it will be terrific, the bad news: it will be MUCH more expensive than the neighbouring focal lengths (i.e. 24 or 35mm art)...

Will be interesting to see how it behaves against the "stellar" Sigma Art 14/1.8 which I tested against the actually quite poor Canon one ... https://www.dpreview.com/forums/post/59871149

Two examples on the 5d3, one single shoot of 20s (f/1.8) and a stack of 6x30s (f/2.0)...

The legacy if the Sigma Art prime lenses created great expectations for me as professional Astronomer when the new 14mm incarnation arrived! A trip to the dark Carinthian Alps under a 21.7mag/"² sky allowed a first comparison with the Canon EF 14/2.8 II prime I used before! I think the result is...

Thanks! Here I did a more detailed comparison with the EF14/2.8II at several apertures: https://www.dpreview.com/forums/post/59871149

Hi! Last week I was able to do a astro comparison between the new sigma and the ef 14/2.8 II . Here are the (clear) results: https://www.dpreview.com/forums/post/59871149
