The maximum amount of Vignetting is 1,67 EV at f/2. That’s definitely worth noting although typical for a fast full-frame lens.

A big advantage of a wide aperture is the amount of light transmitted to the sensor, allowing for shutter speeds capable of stopping both camera and subject motion blur in low light.

Angle of view: 18.8 degrees (full frame sensor), 12.4 degrees (APS-C sensor), 9.5 degrees (Micro 4/3As mentioned, 135mm f/2 lenses, due to their optical requirements, are not going to be lightweight additions to the kit. The lens hood and other exterior barrel parts are made of quality plastic with exception of the aperture ring. One thing I didn’t like was the grinding feel in the focus ring. It got better during the use but still doesn’t feel nice in use. The bokeh can be pretty harsh in long-distance combined with high contrast situations. This is the only situation where I can see a small hint of chromatic aberration although I am sure that most other lenses don’t perform any better there. The size is enormous, that can be a show-stopper. I would only consider to carry this lens when I am sure to benefit of its brightness (portrait, shallow depth of field word) or of its apochromatic correction.

In retrospect, I tend to use Manual Focus for studio-type work and especially for Astro-photography and also for night photography (with cityscapes) and Macro work. With the new Focus Peaking on modern cameras (including the newer EOSM series cameras), I think there may be benefits in using this lens. On the other hand, I seem to have trouble seeing the Focus Peaking highlights on my EOSM6. It usually seems to be visible to me in low light. I've tried the three color options and Blue seems to be the only logical choice for me. Most of the time I can't even see it at work on the Live View... which is frustrating because I'd swear that other cameras (recent PowerShots) were much better at displaying this feature. Lenses – Should have no marks on the elements andoptically clear. There may be light dust present that will not effect theimagery. This shot shows a 100%-crop of the second image in that post. It was taken of frosty branches at slightly longer distance than the bike shot. The situation was extremely contrasty. The branches glitter and show many highlights in the out-of-focus area. This is the first time that I see a slight hint of chromatic aberration in the bokeh highlights. The bokeh balls have hard edges which reminds me a bit of a mirror lens. The overall shot still looks extremely smooth and I think, that this image would have been just purple and green with a “non-APO-class” 2/135mm lens like EF 2/135 L. Nevertheless, the bokeh is not very nice at far distances. Yesterday night I set all the equipment outside to do some (very poor) tests. Many things went wrong, as expected, but that was the goal, find out what's wrong. This includes power and cable management, drew protection, better wifi coverage and test software better (I installed NINA on the field 🙈 🤣).Spotting Scopes Swarovski Spotting Scopes Vortex Spotting Scopes Celestron Spotting Scopes Zeiss Spotting Scopes Eyepieces, Mounts, Cases and Accessories Telescopes Celestron Telescopes Telescope Eyepieces, Filters and Accessories
