I am seeing some old-school 400mm telephoto lenses around the interweb for sale. They are all f/5.6 or f/6.3 with 72-77mm diameters.
What are the feelings of you longer-in-the-tooth members in regard to buying one of these for cheap as a first long telephoto? This would be my training bird lens, until I could warrant a much more expensive and newer lens. I have the Canon 55-250mm IS II, which is actually pretty good for its modest price.
What I know about them:
What I want to know about them:
That's about all I can think of right now, thanks in advance for any assistance you folks can offer.

What are the feelings of you longer-in-the-tooth members in regard to buying one of these for cheap as a first long telephoto? This would be my training bird lens, until I could warrant a much more expensive and newer lens. I have the Canon 55-250mm IS II, which is actually pretty good for its modest price.
What I know about them:
- Manual focus, which is an art-form in itself to get right.
- Obviously, much slower than modern lenses to use.
- They will have no image stabilisation of any sort.
- f/11 is normally the sweet spot for sharpness.
- I would need to have it serviced and cleaned to get it all tickety-boo.
- Potential to get them chipped, depending on model and make.
- May have to use an adapter such as an FD to EF adapter.
- Can be gotten ridiculously cheap if they have some fungus.
What I want to know about them:
- Would they allow enough light in for catching birds in fairly open forest with an ISO of say 1600?
- Working at f/11, would I be able to capture clean shots of birds flying?
- Is a monopod stable enough, or would I need a tripod without any image stabilisation?
- Would it be worth spending the buck$ to have an EF mount fitted?
- Fixed length or telephoto? I'm leaning towards fixed length right now, so I wouldn't end up with a dust bellows situation.
- How hard is it for a good camera shop techie to remove all spore-mould/fungus?
- Look for one that has manual aperture and focus control rings?
- If it's going to cost $300-400 all up, is it worth it, or should I just save up the extra $600 and get a new 400mm f/5.6 fixed lens?
That's about all I can think of right now, thanks in advance for any assistance you folks can offer.
