Hi Marco, would you favour the new 32mm lens over the 22mm f/2.0 pancake for astrophotography? I'm almost certainly going to buy the 32mm but will wait it out until a good deal comes along.

That's actually quite a hard question to answer... the 32mm f/1.4 lens appears to be sharper and is giving me more visible stars and detail than the 22mm f/2 lens. But the field of view is narrower. The 22mm lens is my favorite lens for astrophotography, even over the EF 24mm f/1.4 USM II lens... which produces much stronger Coma on a FF camera but much of that is cut out by the APS-C crop on the EOSM cameras.

If you want to do astrophotography, this is going to be a VERY good lens for faint comets in the sky, lightning at night or for specific regions of the Milky Way. It's possible that it could be used for Mosaics to capture a wider view although without the Lens Correction features turned on, I imagine there might be a problem with light-falloff on the corners. for RAW shooters. Stopping the lens down to say f/2 might be a solution in some ways although then you lose the benefits of having an f/1.4 lens.

The images below - were all taken with the EOS M and EOS M6 cameras over the last 6 years with various lenses. They should demonstrate what to expect with a non-guided tripod and simple, single exposures.

Thank you for the detailed reply. Some lovely ones there. The 32mm lens works out about $650 in the UK so you can probably see why I'm waiting for a while. Canon may do a cashbook offer or something.
