Canon 135mm F2 L vs Canon 200mm F2.8L

I'm toying with a new lens... I had thought a fast macro that I could use for Astro, but I'm getting greedy on reading reviews etc to go for a prime astro lens, either the Canon 135 F2 or the Canon 200mm F2.8....

I've found an Australian importer who sells the 135mm for $1107... but they have the 200mm on special for $889. I'm sorely tempted.

What do you guys think of their relative merits at these prices... is 200mm going to be too restrictive on popular wider objects with the 40D sensor... eg Magellenic clouds?

Help me spend money

I think 200mm is too restrcitive for mag clouds, my 135mm prime focus is a squeeze for them as well though

As a bit of a guide the crux constellation fits in the fov of my 135mm, with nt a whole lot of room left - for the magellanic clouds I would have thought a portrait lens sixe of 80-100mm would have been best, canon ha a good 100mm macro I believe

Robert, either lens is perfect for the job.
The 135mm is very very sharp, and fast (one of my favourite terrestrial lens).
Beautiful bokeh and colour rendition is second to none in it's class.
The 200mm is again superb, very sharp and perfect for astro and great for terrestrial too, do a search on some camera forums of photos taken using these two lenses, you'll be amazed.

They are both fantastic for astro, the 200mm great for comets as well and you can team them up with a 1.4x or 2x T.C and have more versatility.

I'd be hard pressed choosing between the two, I love both.

Attached is a SN screen shot of the fov they both give on the 20Da which has a similar fov to your 40D.

This is one supplier that I deal with, great service, never had a problem with them, they list the 200mm for $879, the 135mm for $1099.
Check out their site.

Thanks Andrew, this is exactly the sort of info and opinion I was seeking. No closer to making a decision though, I'll let it bubble around a bit, maybe I need both

Robert as some have already mentioned both are great lenses, however If I had to choose between either it would be the 135mm F/2.0, you will not get a better all round lens, but that is only IMHO.
