Yep had the same problem with a Vivitar 28-200mm.
You need a junior hacksaw, a fine file, and a very steady hand with which to reduce the size of the shield so that it matches that of (say) a Pentax M f2 or 1.7 or similar. The metal is very soft and easy to cut but you would be wise to ensure that no metal dust gets into the lens!
Finally a small artist paint-brush and a little matt black paint.
Best of luck

Good luck....
PS. When you remove the mount, do so carefully and avoid removing the aperture ring as re-locating the minute ball bearing that defines the click stops can be a pain...

The 8-16 club link is also a good place to see some exceedingly fine examples of what this lens is capable of.
Whatever you buy, enjoy it...

I'm seriously considering an upgrade to a Mark ll, but it all hinges on whether there is a significant improvement in low light MF focusing to make it a worthwhile investment. Your fine examples are just the sort of affirmation I've been seeking.
Thanks again...

If you are not familiar with either Win 7 or Win 8, before you commit yourself, consider going into a local PC World or Curry's or Tesco's even and have a look at some laptops & PC's that have Win 7 or 8 installed to get a feel for each them. I strongly suspect you will favour Win 7 over 8 as the latter is more akin to a phone app in the way you navigate it.
Your graphics card won't give you much of a boost either as a graphics cards main purpose these days is in 3d applications not 2d such as photo editing.
To be perfectly honest and if your budget allows, I recommend you get yourself a new motherboard, a multicore cpu ( I think AMD still provide the best bang for buck) and a minimum of 8 gig of ram and do a rebuild.
You could probably get a cracking bundle deal for the above items if you shop around for well under £200, which should prove much better value in the long run and be ample capable of running Photoshop on a 64bit OS.
Depending on how computer savvy you are, Windows 2008 server OS converted to a workstation OS is a dream to use and supremely stable. Otherwise, Win 7 should be just the ticket for you.
These are only my thoughts however but based on years of PC building and using. Others may disagree as is there right...
Good luck....

Ok tried my mkii today wi my 400mm f/4 and the focus locks on just as quick as an af lens, soon as the shot is in focus beep, not like the mki where you have to step backwards and forwards.
I will post some results tomorrow..
Thanks again and I'll look forward to your results....

Actually less of a stupid question than you suggest. If the low light autofocus is so good, is the focus confirmation when using manual focus lenses in low light equally good? Often it can be difficult to focus manually in low light so it would be nice to know if the focus confirmation can be used to help.
Best wishes, Kris.
Thank you Kris, you understood my question and moreover proffered a sensible reply!
