I have just picked up a second edition one (with the rotating tripod mount) and a 2x converter, both Mint, for £500 the pair.

 

I am looking forward to giving them a run out at a hill-climbing event I have been invited to on Sunday.

No I didn't. It's a mare to use.

 

(Actually, it's a joy to use and will be in the For Sale section here tomorrow. Get a decent bid in quick before it goes...:D)

 

When you get it right, the images are fabulous. Just make sure you are using a DMR, or you will be bankrupt before you can say "almost got the little beggar in focus".

 

I'm thinking of putting the 2x converter in between, for my next birding expedition. "Think outside the box" - that's what it's all about... ( 560 x 1.33 x 2 = 1489mm at f 13.6 max. No worries :) ) Good job the DMR is good to go at ISO 800 now ;)

Andy,

i beleive the crop factor is 1.37 vs 1.33 - with the numbers your talking it might make a difference: 560*2*1.37= 1534mm -

 

Also i hope you have a good sturdy tripod.... btw: what do you carry your gear in a wheelbarrow ? lol

 

wholly crap... that is one small angle of view....anyone one know the degree?

 

have fun !

The first version is: Fatter and stubbier than the 2nd; has a longer close-focus limit; has a MUCH longer focus throw (distance the ring must be turned from far to near) - which may explain Steve's "pig" comment; and struck me as slightly snappier in contrast but with more color fringing.

 

The 2nd version has partial internal focusing, which allows it to focus closer faster - but it also makes it quite a bit longer.

 

V1 - 6 elements, V2 - 7 elements, which may explain the difference in contrast.

 

Net: V.2 is a bit more convenient and easier to handle and (IMHO) slightly nicer for color; V.1 is a bit snappier for B&W or on gray days.
