Camera Lens for Axis IP camera
I want a lens, with f number 5.6 and also a pretty good angle 90 degree or more.
The reason for the greater angle is to encompass a greater view, similar to a panoramic view
The reason for a smaller f number is to gave a good focus from 2 meters to infinity.
Lens mounting systems is CS.
Sensor.of camera is 1/4"
Model of camera is Axis P1344
The camera will be used in a more daylight situation. So now I just need a lens manufacturer that makes these kind of lens and maybe a price.

thanks for answering
the p1344 or the p13 series have from what i see in the manual the cs mount system
regarding that website i saw it some time ago but I don't know why I can not find an F5.6 lens.
This idea of mine come from axis's website where they say
Iris opening and depth of field. The below illustration is an example of the depth of field for different f-numbers with a focal distance of 2 meters (7 feet). A large f-number (smaller iris opening) enables objects to be in focus over a longer range. (Depending on the pixel size, very small iris openings may blur an image due to diffraction.)
But in axis p1344 user manual found here
http://www.axis.com/files/manuals/um_p1343_p1344_37344_en_0912.pdf
they say:
AXIS P1344:
• Varifocal 3 - 8 mm, F1.2, DC-iris, CS mount
• Horizontal angle of view: 32° -74°
• Vertical angle of view: 17° - 41°
• Diagonal angle of view: 32° - 84°
• Remote back focus
• Focus range: 0.3 m to infinity
So why they say that a higher f number will focus into infinity when they say also in the manual that the F 1.2 will also focus to infinity.
I don't understand if the picture is wrong or I missed something.

spoke with axis and they said it's not possible to use the iris on manually it's only auto. I hope this will not change things much when I mount the camera outside.
You were saying that I need a software to fix the picture on a 360 deg. lens. Any idea of such software that runs on Linux ?

Do you have the camera or are you just looking at buying it?
If you have it I would still give the HTTP api a try just to see. The customer support may have meant you cannot control it through the web control.
The Immervision lens SDK supports linux though this is not a 'finished product'.
http://www.immervision.com/en/security/security_immersive_viewing/sdk.php
The autoiris is designed to give the best possible result for the camera and I really think you will be farther ahead with it than a manual f5.6 setting. So if you have the camera give it a go and see what you get. The 3mm on the varifocal is going to be about as good as you get. Though I find on some cameras I simply cannot get the widest view to focus properly, I think the Axis unit is around 75-80 degree maximum. Depends on the conditions.
If you do not have the camera there may be better alternatives for wider angle shots than the Axis products. Some of Mobotix cameras support a native wide angle shots,
http://www.mobotix.com/eng_US/content/view/full/2
They do a nice panoramic shot that is not distorted and they do have a 360 camera. It's native picture is similar to the Immervision native view and I am not certain if the interface works on linux to give you the corrected view (I don;t know if the work is done in the camera or the computer).

I know about the mobotix, I tested the M-24, it was great but I needed H.264. I also know the Q but again mobotix camera do not use h.264 and I need it.
That's why I was asking if you knew about a software correction tool for the 360 deg. lens.
I will have the axis camera soon and I will return with feedback after I test it.

I tested the camera, and it's ok, now I just need to know if a software can correct the deformations caused by a 360deg lens and offer a panoramic view.
ASKER
I have moved on, like the current lens, still don't really know how can I correct the distorons of a 360 deg lens, but that is not a problem now.
Thanks

Axis does not advertise their P13 series cameras (such as the P1344) as having interchangeable lenses. If the mount is indeed a CS mount, you can mount any manual CS lens on the camera (losing automatic or computer control over iris and focus) Take a look at http://www.videologyinc.com/lenses/camera-lenses.htm for some good wide-angle f/1.2-1.4 options. You're probably looking at prices in the $30-70 range on a one-off basis, or less if you are looking to buy in bulk.
