The only camera I used was my Canon with the 100-400 lens, with which I normaly take 80-90 percent of my wildlife pictures. Checking the files, I first thought "oh man I need some practice focusing correcty", my second thought was "I cannot focus as bad as this", my third thought was "it cannot be me" as all pictures where not only unsharp but a bit blurred over the whole zoom range.
A quick test with another Canon body/lens showed the proof. The lens was broken and it was my only long lens I took along!
Somehow I took this disaster much lighter as you might think, I could not change it anyway and I was guiding a workshop and taking own pictures is always nice, but I was the guide, full stop.
Moreover I thought, lets make the best out of this disaster, take it as a challenge and use the medium format body and lenses as main equipment. I am very pleased with the results and the pictures differ a lot from the pics I took 2 years ago with a full working Canon combo with 100-400 lens (and only few shots with my medium format equipment). But you should know, that wildlife in the Falklands can be, albeit with great care, approached very close. Had this happened in Alaska or Africa, it would have been a different story! A 400 or 600mm (full frame equivalent) lens would weight 10-30 kg and is not available anyway. The longest lens I used was a 300mm full frame equivalent, most of the time I used 110mm (full frame equivalent) or wider down to 20mm (full frame equivalent)
Very occasionally I borrowed a Canon lens from one of the participants (many thanks!), but only if I was sure, that we could swap lenses immediatly. Nearly all shots you see in this blog are shot with medium format. It was a challenge but it worked, somehow it was like using film bodies in the early 90ies....
