as I want to take photos with my family and use David too, I decided to buy a Canon digital cam. Now I am selling my PointGrey CMLN-13S2M-CS CCD USB2 cam. Exact Details you will find here:http://ww2.ptgrey.com/USB2/chameleon
2 objectives are included: Lens 1/3" 50 mm F1.8 and lens 6.0-60 mm F1.6 1/3" CS. Drivers and software is included but you can download it on PointGrey website too.
It works with David but it needs a little time to configure.
If you are interested to buy it (€ 350,- including shipment) please contact me: firstname.lastname@example.org
