100-400mm mk1
« on: January 09, 2015, 08:48:28 AM »
Hi all

Off to view a 100-400mm mk1 tomorrow morning. Anything I should look out for. It is listed as £500 on a local selling page.

Many thanks for any pointers

Just the usual: get some photos but long range and close as you can get to check for sharpness. You may or may not get tack sharp at full zoom (in fact, I wouldn't count on it) so you might need to pull back to 350-380mm or so and then check for sharpness.  I could never get tack sharp at 400mm but it could be me (although it was pretty common with people who review those things too).
When trying the "Push/Pull" part, listen for any noises (like grit or sand caught in there). It should be quiet.  Loosen that Tightening Ring and ensure it moves in and out smoothly. Then lock it down and try to move it in and out: you shouldn't be able to.
Good luck!
Take your camera with you dammit. You can't take your next "best photo" if your camera is sitting at home in the bag, now can you?

And with the mkII out now, it's definately a buyer's market for the mkI!  Offer £450 because he/she wants your money to buy the mkII.
