So the consensus seems to be that the 50 / 80 / 150 kit is popular for good reason. One would choose the 50mm for a distinct wide angle feel (somewhat akin to a 28mm on 135 format) and my thought of the 60 / 150 kit only if I intend to keep within a targeted subject or general purpose subject matter.
I suppose versatility should win out here.
So, say I decide to go for the 50, should I hunt for a C or a CF? If I choose C, both of my existing lenses would match, but if I choose CF, it would benefit me to upgrade the other two lenses as well, which naturally will increase my overall cost, but will potentially be better in the long run due to limited serviceability of the older C lenses. What are your thoughts on this?
If your budget can afford the CF and upgrading the others then go for it. If not do not hesitate to get the C, just get from a good, reliable source.
If you can get a CF get a CF, if not get a CT* and be happy. Whatever you buy does not mean you have to change your other lenses, why do you say that if you get a CF it will benefit you to swap the other two lenses?
Common filter size. That is about the only real (practical) benefit of having all lenses of the same type. Althopugh I ahve read about some people getting "confused" when using some lenses with EV lock and others without... but my opinion on that is that practice and regular usage cures that kind of confusion.
If you come across a good deal on a 100mm Planar, I would recommend one. Use 60mm and 100mm and if you need longer, get a 150mm Sonnar.
I keep wondering, how wide would I really need to go? I really like the thought of the 60mm as I understand it's really easy to handhold and not have to worry so much about perspective distortion as one would with the 50mm. Though I do quite enjoy a good wide angle as they're fun to use.
I guess the best thing to do would be to rent / borrow those two lenses if possible and see which one I like better.
FWIW, for the C lenses, the 60 doesn't use bayonet filters, so filter compatibility isn't an issue, I think this is true for the 50 C as well. There are series to bayonet adaptors that let you use the series filters for the wides on the bayonet lenses though.
Hasselblad Historical has a nice chart for comparing focal lengths between formats;
I found that the 60mm was too close to the 80mm.
I have only CF lenses: 38mm [SWC], 50mm, 80mm, 150mm and 250mm and I am happy with that combination. I would also recommend 38mm [SWC], 50mm, 100mm, 150mm and 250mm.
Thus the reason for my name.
