EOS RP with RF 70-200mm F2.8 L IS USM for astro I am evaluating the RF 70-200mm F2.8 lens for astro. So far I am reasonably impressed with some preliminary results (comparing to a 135 mm Rokinon prime lens). I have a question about a bright star flar...

I currently have a new Canon EOS RP camera body and so far, have only one new lens .. a fully manual Rokinon 135mm f/2 mainly for astro .. it works very nicely for both astro and regular photography. I ordered a used Canon prime EF 200mm f/2.8 but ...

I noticed that there are some red spots in the images of time exposures I've taken of star fields. Zooming into the images, these are about a pixel in size and as seen in attached zoomed image are red. Picture taken with a Rokinon 135mm f/2 lens with...

What is the battery drain time for the modest EOS RP camera with a modern lens like the RF 70-200mm F2.8 L IS USM under typical usage conditions? Is there a substantial difference when used in fully manual mode or with AS turned off? Is it the same f...

I'm deciding which of these RF70-200 f2.8 lenses I should get (new). The difference in price is roughly 10%. It will be used with my EOS RP camera. It will be the only lens I use (apart from a prime 135mm lens). I've read several reviews comparing ...

thank you for your valuable comments here and in my other posted topics here. I appreciate guidance by experienced folks such as yourself (I'm somewhat of an old timer and have taken up low-level astro within the last 3 years).

I stopped down the lens from f/2.8 to f/3.5 and that cleans up the dark-band flares. Two attached ~1900x1600 crops from original L jpg 4160x6240 of Vega region shows the expected reasonably symmetric star ray pattern for the aperture blades. Both at ...

thank you. Yes the Rokinon 135mm prime is fantastic. I bought one a few weeks ago. I needed one very high quality general use zoom lens for my Canon EOS RP for both typical photo usage as well as nearer nature photos in the 70 - 200 mm range and reas...

some results for basic star shots with this Canon 70-200mm lens: Canon RF 70-200mm F2.8 L IS USM & Canon EOS RP

thanks for all the replies. For context, my ES RP is very new and Im very careful with not letting the camera body open except for very brief moments. So I think my results represent a typical result for a new camera sensor. I setup a fairly dark bas...
