camera sensor size?

Fri May 17, 2013 5:44 am

Hi Guys,
from a little interwebs digging, looks like the camera module's using a 1/4" sensor, 65 degree field of view, F2.8 Lens (nice and fast!),
Question, is the lens formally 'stuck' into the sensor module housing?
looking at the images I can find it seems there may be some manufacturing adjustment allowed for to focus the lenses - as there's an almost screw fit looking setup to the lens.
If no answer, i'll fill out these details once I receive my two, I'll wreck one in the name of science to see if other lenses can be attached

Yes,

there is a screw lens but it is glued into place, but P33M (from the forums) has been able to remove the glue with a scalpel and change its position making it quite a nice macro camera!

Thanks to M33P's post - http://www.raspberrypi.org/phpBB3/viewt ... 70#p346170

there's three small lumps of epoxy on the lens thread,
I found gently scraping them off with the tip of a pair of scissors - took about 5 min - freed up the threads enough to be turned with a small clamp (not a pair of pliers as they won't grip evenly),
if you don't have a small clamp device, pliers may well scrape the lens if you don't grip well enough,
it'll also crush the lens if you grip too hard
- i'd suggest maybe also a grippy surface - something like a rubber mat?

there's a custom 3 spoke type setup to actually grip the lens

Thread's much smaller than anticipated,
