I'm looking to get a 250/5.6 for my V system, mainly for landscape use. I've found a few of these but not too sure which one to go for. All with clean glass:
250C for £150-250
250CT* for £200 (not so sure about glass condition on this, need to check)
250CF for £500
Now I don't particularly like the handling of C lenses with their fiddly constant aperture coupling and heavy focusing but since I'll be using the lens not that often on a tripod I reckon it won't matter that much. Would you say it is worth getting perhaps an older lens and getting it serviced (costs about £100-150 to service) so I have a "new" one vs getting a CF that might need servicing in a few months?
Also, is there an obvious image quality difference between the C, CT* and CF versions? Because if a CF is visibly better than a C/CT* I'll get one of these.
