There are some days I hate photogrpahy.. its rare.. very rare.. but today is one of them
£73 quid to clean, calibrate and test focus..+ 70 quid fuel to get the lens to them.
Its back and worse than when it went.. it was usable at f5.6 for cricket before.. not now
I have two 1dmkIVs that have been calibrated.. I can take a pic form 50 yrds away at f2 using the 135mm lens.. I can take pics the full lenght of a football pitch with the 70-200 at f2.8 and produce good pictures.. So the cameras are calibrated OK and indeed they where calibrated at leihmans in stoke about a yr ago.. I know they are perfect
So the 400mm that was bad at f2.8 , usable at f4 and pin sharp perfect at f5.6 now comes back unusable at any of those
so phone in hand....after the runaround with canon I get a special number for cps users... an hr ago I explained everyhting and he is going to get back to me..
upset to say the least
