With the USD falling to new low levels almost every day, I have decided it is time to add a third lens to my Hasselblad. Today, I have the CF 60/3.5 and CF 120/4 with which I am very pleased but now I'm looking for something longer; the 180 or 250mm (non-SA). They are both heavy pieces, over 1kg, and not exactly cheap even though they are cheaper than a few years ago so I will only buy one of them. There are pros and cons with both of them, the 180 is a stop faster (f/4) and reputably sharp whereas the 250 is cheaper and more readily available second hand. I've read a number of people stating that the 250 is a low mark in Hasselblad lenses when it comes to sharpness but these are the same people that claim the 120 makro-planar is useless on distances over a few meters. Not having noticed the supposed 'uselessness' of the 120mm I wonder if this sharpness issue is something I will notice without a microscope? Another advantage of the 180mm is the fact that together with a 1.4x converter I will get 250mm f/5.6. It comes with a stiff price though, the 1.4XE is almost the same price as the lens. The 250mm Superachromat is way out of my league even with a cheap dollar so please don't suggest that. I have no doubt that it is better than the plain 250mm but I can't find or justify that money. Can I have some opinions here? Anybody got or tried both?
