Hi, I currently own a 180 CFE and am considering selling it and getting the
250 CFE SA in it's place. I have trawlled through this forum extensively and
have not been able to find a post or comments that make a direct comparison
between the 2 lenses. I have no doubt that the 250 SA is a sharper lens with
better resolution and colour rendition, but the 180 is rather good too. I am
asking this because Kornelius has mentioned several times that the 250 SA is
the finest lens available and I was wondering if anyone had compared the 2. I
shoot mainly landscapes and portraits. I recognise the advantages of the 180,
being a full stop faster and being able to focus much closer. Thanks so much
for your comments.

You can download the MTF's of the two lenses and see for yourself. In my view, the two lenses serve different purposes.

Can you provide a link to the MTF data? Thanks.

The MTF's aren't photos. The story is told by the results of the photographs. I have both
lenses and generally use the 250 CFE SA 90% of the time and it gives outstanding results. I
too shoot primarily landscapes with it. The 180 is a great lens and I don't hesitate going to
it if I need a little wider perspective, but generally the 250 SA gets used by far the most.

I'd suggest you google to find the MTF's...

CPeter Jørgensen:
MTF's aren't photos, I agree, but my experience is that people who worry about whether one lens is sharper than another are more concerned about lpm measurements than actual photos. In any case, MTF graphs are seemingly the most objective data easily available, such as it is, on lens characteristics and are not influenced by individual photographer characteristics or biases.
As I said, I don't think one lens replaces the other, so it's not a question of which lens is sharper.

Good advice, Wai-Leong, after John told everyone where to find them...
;-)

It's never too late to learn about Google.... what if John or you weren't around to help today?

"It's never too late to learn about Google"
Maybe. But the Hasselblad Historical site is one about which every Hasselblad owner or ogler should know. If you've got a question about Hasselblad equipment, Hasselblad Historical should pop into your head before Google.
(Even though I'm otherwise a big fan of Google.)
