thazy2 0 Posted July 22, 2010 I just purchased the unit used but i dont think its the right lens, Computar 4.5-12.55 1:1.2 Ir1/2" CS made in Japan. Any ideas? thanks. Share this post Link to post Share on other sites
Soundy 1 Posted July 22, 2010 Other than it maybe not being a "megapixel" lens (your description doesn't say), I don't see anything "wrong" with those specs. Share this post Link to post Share on other sites
thazy2 0 Posted July 22, 2010 Thats what i mean. I cant find anything on the lens stating its for megapixel cam. I think the pic on this cam should be better. I have reason the the original purchaser installed an improper lens. Could anyone recommend a lens more suited for this Arecont to get the best quality?

Soundy 1 Posted July 22, 2010 You want the specs to include "1/2 inch", and "megapixel" (or MP). If it's a day/night model, you want it to be "IR" as well. Beyond that... anything for focal length that suits your needs. Share this post Link to post Share on other sites

megapixel man 0 Posted July 23, 2010 If your looking for a similar focal range to the lens you have then try this one, good lens for the money and will match the sensor of the Arecont 5MP. Auto Iris http://www.syopt.co.kr/eng/product/scvhm4012asir.asp Also available in manual iris http://www.syopt.co.kr/eng/product/scvhm4012masir.asp Share this post Link to post Share on other sites
Baylab 0 Posted July 23, 2010 Have some experience with Computar's 4.5-12.5mm lens. Should be OK for 1.3MP camera. for any camera with resolution higher than 2MP, the image is quite soft, even in central area. I don't think there is any off the shelf and "affordable" lens which can match 1/2.5" 5MP sensor perfectly. Share this post Link to post Share on other sites
thewireguys 3 Posted July 23, 2010 Wonder what lens Axis is using on the 1347 5MP since they where claiming the lens technology was not good enough for 3MP and up. I was also told that Axis tries lens from every manufacture on each camera till they find the best image. I have the P1346 and the image quality is very good. http://www.axis.com/products/cam_p1347/ Share this post Link to post Share on other sites
buellwinkle 0 Posted July 23, 2010 Not made by Arecont they are Kowa lens http://www.kowa-usa.com/frontend/proddetail.asp?pn=LMVZ41&co=10000343 Quite possibly, but a lens maker can make a lens to a different spec for an oem manufacturer. The lens in that link does not look anything like the Arecont branded lens I have. Share this post Link to post Share on other sites
hardwired 0 Posted July 23, 2010 That Kowa lens that Wireguys listed (above) Looks exactly like the Arecont branded lens I have (below). Problem is, neither of those are from Kowa's Megapixel line of lenses, they are just standard res lenses. Kowa's true Megapixel lenses work MUCH better.....

thewireguys 3 Posted July 23, 2010 Which is the same lens that I have and the same lens on Areconts web site and my product sheets. Share this post Link to post Share on other sites
buellwinkle 0 Posted July 23, 2010 Mine is different, it's F1.6, 4.5-10mm. I think when I tried to order the F1.8 4-10mm, it was discontinued or the distributor made a mistake. I am fairly certain it's an Arecont lens, came in an Arecont box for my Arecont camera. Share this post Link to post Share on other sites

buellwinkle 0 Posted July 25, 2010 The image quality from it on my old AV3100DN was quite good. I dumped the camera on eBay but forgot to sell the lens. I was hoping to be able to use it, maybe get a cheap ACTi cube like Hardwired did and put this lens on for a better image and varifocal capability. Share this post Link to post Share on other sites
