Originally posted by iheiramo I'm pretty convinced that full frame is the best format to own if one love's to shoot with manual vintage lenses. Those lenses just seem to work better in the format they were designed for.
To you these older lenses may seem to work better with FF when in fact they deliver better quality images when used with APS-C cameras.
That is quite easy to explain. Only part of the image cirkel from FF lenses is used to deliver the image of the APS-C sensor.
The outer parts where almost every lens shows a decline in quality is not used.

Try to think what would have been the situation if the APS-C format would have been first and FF came later.
FF would have had a had time to beat APS-C.
The reason why many of us are tempted to go FF is the use of wide angle lenses.
It was difficult to find a nice WA zoom lens for my K5.
I ended up with a compromise towards the WA range with the Sigma 17-50 2.8 lens.
Pentaxs 16-50 was not impressive when used at F2,8.
