There is big difference between 135mm F5.6 C Macro (~£250ish) and the 120mm F4 CF Macro (~£850ish).
So I'm curious to know if the price difference is all that comparable to results? I am used to using a 2.8 60mm Nikon Nikkor Macro lens (before it was stolen) with my F5 and I had great results with that - I am looking for a Macro lens of similar optical quality of that for my Hasselblad. I appreciate a 2.8 Carl Zeiss is gonna cost big, but I hoped the quality of say an f5.6 might still be pretty good in the Hasselblad world?
Yes, the 135mm can only be used with a bellow unit, since it has no built-in focussing helicoid. If you only intend to do some close ups in studio/at home this won´t be much of a problem, but carrying it around may be a bit awkward. I would go for the 120/4 CF. There is also an older version (120/5,6 S-Planar) available as C or C T* Lens. It is the predecessor of the 120/4 Makro Planar and every bit as good optically, apart from only being f 5,6. In case you want to save some money, this would be my recommendation. Just make sure the shutter is working properly.
Thanks for the help and info guys...I will probably go with your recommendation Slixtiesix...once I have enough spare pennies not to annoy the wife by "another photographic expense"!!
I agree that extension tubes are a good way to go. I was using the Mamiya RZ system and love macro. The bellows focusing allows almost any lens to be used for close up and extensions tubes increase the magnification. Initially, I was frustrated with the Hasselblad because it does not have the bellows focusing. Then I discovered the extension tubes. With these, I can get great macro shots regardless of the lens.
If you already have a 150, I'd agree with others that you should try an extension tube. If you don't, the macro is more convenient. Either way, the Hassy macro isn't close to 1:1 so you will probably want tubes anyway. Dead Link Removedis the Hasselbald page that compares extension tube vs lenses. Worth the read.
The Makro-Planar is an outstanding lens. It is my favorite for many reasons. I find it matches my particular photographic vision more closely than the 80mm. It is not the same as a macro or macro-zoom lens on a 35mm, however. You'll need extension tubes to get really close.
