I have to admit I have been struggling with my combo of the 1Dmkiv and the sigma 150.600 sport ,soon after purchase I did my usual micro adjust and as most will know I have been getting some superb close up shots with it ,BUT I haven’t been totally happy with mid to long range shots that require a degree of cropping .so this morning I bit the bullet and did a mid/long range MA using the roof of a house opposite as my target ,ridge tiles on the corner sloping at a 45degree angle .totally different result ,I have now had to dial in minus 5 to achieve a sharp shot and it might need more yet .
Sunday’s hen harrier shots were the deciding factor as last night I came very close to e.baying the whole lot .hopefully this will work better
to illustrate I have added some pics below as direct uploads first off the roof used for m.a at 36.5 mtrs lens set at zero, next with it adjusted to minus 5 and finally a number plate on a car over the road distance 71.2 mtrs away this shot was testing under working conditions so hand held ,I think the resolving power says it all, on my version of the number plate I can clearly read the middle row of lettering
