Many thanks Chester AP. The safari is a honeymoon trip so I expect he will want to make A4 enlargements of the best, either for a wall picture or album/photo book and yes, the camera is likely to be a bridge style camera and likely to have a 1" sensor. Given the cost of most such cameras new, it may well be second hand, purchased from a reputable source with guarantee and definitely some months before the trip. Was the lens that your friend used a 400mm equivalent, that is around 260mm in reality, given the APS-C sized sensor? Did he feel that was long enough and was he happy with the results?
