    1/3 camera and a 2/3 lense?

    Thanks NumbNuts The dead camera I am replacing had a 16mm lense on it, which was almost OK, perhaps could have done with zooming in a little more. It was not very good in low light/dusk. The new camera (1/3" CCD) I've already purchased, because it's low light. It's on the eBay link in my initial post. This camera is a 540TVL and says it works down to 0.01 lux. The new (actually used) 2/3" lense that I've also bought is a 10-140mm zoom, which I intend to just manually zoom until it's just covering everything we need to see. It's a Pentax/Cosmicar C31010 or C14ZME. My main concern was the 2/3" lens working with the 1/3" CCD in the new camera, and whether it would work OK, as it was something I stupidly overlooked. Interestingly, I've found a spec sheet for the lens which shows some "horizontal angle of view in degrees" for the 2/3" lens in columns for 1/4, 1/3 and 1/2 inch formats, but I don't know if this means if I use that lense with a CCD of that type?? With a 1/3" it shows an angle of view as 26.41 - 2.02. The table is here if anyone could try and make sense of it for me: http://www.cs.unc.edu/Research/stc/FAQs/Cameras_Lenses/Cosmicar-Pentax.pdf and the lense is the second up from the bottom on sheet 4. Annoyingly neither the camera or lens haven't arrived yet, so I can't try them, so I was just wondering if anyone can confirm if they'll work together??? Thanks Rob

    1/3 camera and a 2/3 lense?

    Hello All Before I ask my question, let me please first apologise for not being a CCTV professional, so my question may have been asked already. I'm not a complete numpty (hopefully) and have a background in networks, so hopefully I'll understand your answers. I'm not sure whether I've committed a bit of a faux-pas, in the interest of trying to improve a camera installation my sister has on her farm. Basically she has a discreet camera (inside a dovecot) covering the entrance to the farm, keeping an eye on vehicles visiting and loitering. The old camera died, but was never really great, as the position faces west so was prone to being blinded by the setting sun. The old camera (not sure what make) was day/night, fitted with a 16mm lens, but didn't work very well in low light (compared to newer domes there). The gate is located about approximately 7 metres from the camera position, and my feeling was we needed a bit more zoom than the 16mm lens gave. So, to my dilemma... I thought I'd purchase a zoom lens on eBay, so I could manually set the zoom to get the best coverage. I ended up winning a Pentax/Cosmicar C31010 (C14ZME-P) lens, which says it has a C fitting, but (this is the bit that concerns me) a 2/3 inch format. I'd also found a low light camera on eBay at what seemed a good price, but this has a 1/3 CCD sensor, so my question is, can I use them together?? Also, as I haven't purchased the camera, what is your professional opinions on the Starlight 540TVL listed on eBay, which I'd intended to buy? http://www.ebay.co.uk/itm/220888194206?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 All answer greatly received (keep it clean though!!) Many Thanks Rob
