Might find this and the subsequent response from dave and cofe a useful starting point.

Good advice from Dave, I missed you were on Nikon, Canon do a 400.5.6 that would be ideal, on Nikon you're stick with various 300s. Beware of the sigma 300/4, not all work on newer bodies.

There are old manual primes out there that may work with an adapter, and some (very) manual aperture control. Mine was a Sigma APO 400/5.6, decent and small. If they made them in Olympus there must be some around in Nikon. I don't need mine anymore but it doen't look like it would be possible to adapt it to nikon.

MXV has just gone bust. They were one of the best second hand shops.

The other other option for the deperate would be to find a 500mm f/8 reflex lens. But personally I'd sooner roll up down the bird-hide with a 50mm f/1.4 with three stacked x2 teleconvertors. shick-a-ding.

That is well outside the fucking box. Good call. Underrated lenses actually, nearly bought one for the eclipse. SonY are making one, the doughnuts will rise again.

Get a grip, you still think that lens is bad? They can't all be perfect.

Yeah - I was impressed with the 10-20, very nice :)

I doubt I would buy another Sigma though, too much of a gamble..

What about the other other other option of this?

I can't walk closer, but a few modifications to a clip stick could get me:



I'll need to beef up my arms a bit first though  :(

Unless anybody knows of a cheap way (under £250) of getting a 400mm zoom? Second hand 400mm lenses seem to go for extortionate prices on Ebay.

Who What are you planning to stalk take pictures of that requires such a long focal length?

If the picture really matters, and its a one off then definitely just rent a lens. http://www.lensesforhire.co.uk/ are suposed to be very good. A 400mm L will only cost £50 for a week, and the image will be miles better (allowing tighter crops) than the other options you are talking about.

Even 400mm is not a lot for birds in the wild, so quality and the ability to crop is vital.

400 L is no good on a nikon though. Closest on that site for £50 is the long end of a 80-400vr, which is a good and handy lens, i've used one a couple of times.

Of course the buying-then-selling option is more effort but is effectively unlimited rental for free if you do it right.

Good point, and well presented. I may have conveniently forgotten that the question was about Nikon.

My point is that a decent lens is relatively cheap to rent and is capable of producing a much better image than a cheap 300 with a teleconverter.

Talk Photography has a lot of second hand stuff on it if you fancy that route; as Dave says its a virtually free way to get the use of a lens if done cleverly.

That is my favourite shirt I have to say. I find best way to check for lens issues is to look for this lettering on the side: 'SIGMA'.

I'd love to be able to get a 400/5.6 for £50



Seventy quid c/w nikon mount. These have a good rep.

the downside is you're likely to get taken out menezes-style by the met as soon as you use it.

Brilliant - thanks very much for posting this...

I will start to do some research - it does look like fairly hardcore though  :lol: :lol:

I'm not sure I'd be taken that one on holiday...
