I bought the pen as my 'backpack camera'. very interested in the possibility to work with a Gigapan panoramic robot. Anyone around that tried it already? cheers Charles Hi,

Interesting stories. I bought the pen as my ‘backpack camera’. very interested in the possibility to work with a Gigapan panoramic robot. Anyone around that tried it already?

cheers

OK so basically a 25mm f1.4 lens mounted on a micro-four-thirds camera gives a field of view equivalent to a 50mm f/2.8 lens. Now, you're right of course that the speed doesn't change at all - that always stays the same. But the depth of field is not going to be equivalent to a "true" 50mm f1.4. So, if it's shallow depth of field you want, it's a disadvantage when compared to full frame. If however, you want a greater depth of field while retaining the fast lens speed, it's actually an advantage. Make sense? Hey Seb… yeah this often confuses people.

I'm not sure if what you're saying is right. The lens speed doesn't change on 4/3. So a 25mm 1:1.4 become a 50mm 1:1.4. You can watch c mount video tests on my GH1 here : www.vimeo.com/sebfarges Hello,

I’ve read in your post this :

” On a micro four thirds, you have to double these measurements, so a 25mm f/1.4 becomes a 50mm f/2.8 equivalent field of a view to the 35mm format”.

I love the filmic vignetted look these lenses produce. Thanks for this blog, really useful info here – I have a c-mount adapter on my Christmas list!

Personally I am steering clear of CCTV glass - besides, you can't beat that funky cinema look. Still, would be interested to see what you find.

Interested to see what shots you get with that 28 1.9 - post a link when you have a collection up somewhere.
