dslr lens

[jamie56]

Hi guys,

Got modified canon dslr, not sure of type of lens to go for ie 35mm or zoom like 18/55mm? Any suggestions much appreciated, going to dump camera on scope for dso but was also looking for some lens to do basic sky shots.

You can't go wrong with the nifty fifty! I've had tons of fun with that little lens.

Hi adam,

Where do I find this one, is it available on line

[Adamar98]

You'll find them in most camera shops. Its the canon 50mm f1.8. Nice and cheap. You should pay around £90 new. It's a great little lens.

I would be inclined to look for old M42 mount manual primes. Better quality than zooms, dirt cheap. Pair them with a £25 adapter and you're away.

Hi dave,

Would these lens fit a canon eos using adapters, if so what size lens u recommend ie 50mm, etc

personally i feel the 50mm on a crop body is way to much zoom for my liking, if it were me id get the kit 18-55mm kit lens, its a cracker for under £50, i think i got mine for £20.....

50mm on a FF body is more suited... 

just my thoughts

Hi, are you putting the camera on a fixed tripod or will you be using a tracking mount? If the former you would be better off with a wide-angle lens so you can take longer exposures without trailling.

[DaveS]

I think I would look at the various 35mm focal length lenses. As tingting44 has said, teh ubiquitous 50 mm bight be a touch long on a crop format camera, though as 50 mm lenses are common enough and relatively cheap, you could always try.

Have a look here

For suitable adapters.

I love my pancake 40mm. It goes everywhere with me.

Apologies for slight thread hijack - but has anyone got a link to a decent M42 adaptor?   I got (a very cheap) one for my 600d and my m42 primes wont reach infinity focus.

Have a look at the link in my post above, that's where I get mine from.

I'll try and dig out a link later, another poster recommended me one that gets the lenses a bit closer to the sensor. It does seem to be a slight lottery with M42 lenses though, I still have a couple that don't quite get there.

The Canon 50mm's are good, but you have to stop them down quite a long way. You can easily fit all of Orion into the FOV to give you an idea. The 40mm pancake lens, looks to be a good one too. The best I've used so far appears to be macro lenses. Really flat field, and can be used wide open at f/2.8, I've used a Sigma 150mm at f/2.8 and it works a treat.

As said finding a matching adaptor can be a bit of a lottery sometimes i only ever use the cheap ones advertised as "infinity focus" compatible but have had to match them with various lenses and even had to add a slight bevel to the thread at the lens end of the adaptor to make sure they seat correctly.

The result is that the lenses have a dedicated adaptor permanently fitted (some with the focus confirm chip) some lenses can have the infinity focus end stop adjusted if all attempts to find a matching adaptor fails.

I have a few old Olympus OM lenses for widefield work, they are pretty cheap on auction sites and do a fairly decent job - certainly enough for a start.
