My 1Ds3 had to have a new shutter fitted On holiday a couple of weeks ago I had a small number of pictures with the tell tale white line down one edge. Glad to say the service and repair has given me an as new camera, plus of course the shutter is now under warranty.
The good news is that the annual clean and service means I get a calibration done so AFMA is pretty much not needed.
It is good to be clear what direction ones shooting is going towards as it allows the kit needed to worked out and put out of your head.
I am on a full frame, slower moving route where I am taking portraits of humans and animals (big demand for animal portraits) plus architectural photos of older buildings, so that is the domain of the 1Ds2/3
I still enjoy the occasional sports/wildlife shoot so I will be keeping the 1D4 for that
I expect to do more close-up/macro work so my 7D will be useful for that - as well as for general backup/street
The 1DX that is expected shortly may push out the 7D. The 1DX I see more as a general purpose body which I expect to use as a walkabout/default body. Until PW get their act sorted then it will be limited as I use a lot of flash most of the time .
With the move to ff I have plans for a 300 f/2.8 II in order to compensate for the loss of 1.3 crop - until now I have been using the 200 on the 1D4 - which is clearly going to be shorter on ff. 200 on the 1D4 is a combo which I use a lot, so the new lens will be desirable. The 200 f/2 on ff is my favourite portrait combo - it is flattering for the subject - and the bokeh is just stunning
