kaimaikid 0 Posted September 22, 2010 Hi, I have a Panasonic WV-NP1004E IP Megapixel camera and need advice in choosing a lens for this. It will be pointed basically at the sky being used as a weather cam. I am looking for a varifocal lens around 2.5-8mm, CS mount, 1/3" and auto iris. This is what I am doing with a cheap lens --- http://kiwiradio.blakjak.net/wxcam-history.php So far I have come across megapixel lenses from Panasonic, Tamron and Pentax, would I be better going for the Panasonic WV-LZA62/2 1/3" 2.8-6mm High-Resolution Auto Iris Lens due to it supposedly being matched for the camera or going for something that is half the price like the Pentax C70228DCPS 2.6mm-8mm DC Auto Iris Vari-focal Plus Lens or maybe something else? Biggest problem is that there is very little information about these apart from the manufacturers and I don't want to end up getting a dog. Share this post Link to post Share on other sites

Soundy 1 Posted September 26, 2010 Found your post on weather-watch.com If this is going to be a weathercam, I'm guessing you probably want the widest view possible and won't generally be changing the camera position or field of view... in which case, a varifocal isn't really needed. You can expand your options a bit (not a LOT) by including fixed-focal lenses in your spec. For something really wide, IQEye sells a 2.5-7mm MP lens (don't recall the actual brand off-hand), only drawback is that it's not auto-iris. One other thing to keep in mind: you'll want to use a housing that allows for your wide FOV. This is an IQ511 (1.3MP 1/3") with their 2.5-7mm lens in a Pelco EH3508 enclosure: And finally, if you really want a FULL-VIEW weathercam, have you thought of something like this? http://arecontvision.com/index.php?section=product&subsection=product_details&product_id=25 Share this post Link to post Share on other sites
kaimaikid 0 Posted September 28, 2010 Here is a sample of what I am getting with a basic lens, trying to stay away from the fish-eye look if I can but probably impossible at the wider end of the scale... Share this post Link to post Share on other sites
Soundy 1 Posted September 28, 2010 You can AVOID the fisheye effect entirely with the right lens. Unfortunately that lens will probably cost more than the camera. Other cameras like the Arecont panoramic one have "de-warping" software available that will mitigate the effect. Of course, something like Photoshop will always allow you to "de-fisheye" your pictures as well. Share this post Link to post Share on other sites

kaimaikid 0 Posted September 29, 2010 I have now and that lens looks perfect - I'd hate to know the price of it as it looks rather expensive Share this post Link to post Share on other sites
Soundy 1 Posted September 29, 2010 I asked one of our suppliers about getting in a Theia lens a while back... something in about a 2.0mm for 1/2" camera, I think... seems to me it was going to be about $650. Like I said, "you can AVOID the fisheye effect entirely with the right lens. Unfortunately that lens will probably cost more than the camera." Share this post Link to post Share on other sites
danielsan2222 0 Posted September 29, 2010 The newest one, the SL183, should be going for around $250 or so. Share this post Link to post Share on other sites
kaimaikid 0 Posted September 30, 2010 The newest one, the SL183, should be going for around $250 or so. I like your price better... EDIT: According to their website MSRP is $299 - not bad for a up to 5mp lens Share this post Link to post Share on other sites
