Infra Red photography I use a 720 nm cut off filter for infra red with the HS20. At any zoom greater than 105 mm (equivalent) there is a circular light area that appears in the center of the picture, which gets worse the higher the zoom value. Is there a fix for this problem?

BTW John, what are the first two or three digits of your serial? I just my camera yesterday and it seems to be from the last of the new batch of 1C cameras. I heard the 1A batch from this Spring was bad but 1B and 1C are much better.

You will love this thread---- I got so much info out of it:http://forums.dpreview.com/forums/readflat.asp?forum=1012&message;=38927399Towards the end of the thread he posts his post processing work flow as well as full size images both before and after.

yes, at 105 mm and under the camera does perform excellently for IR, with no visible hot spot I haven't been able to find the references to the hot spot on dpreview.com, can you provide a link to the exact message on the thread? Thanks

I dont think so unless you do post processing. There is a thread on IR with this camera in dpreview.com check it out on how to remove the hot spot. How do you like the IR pics with this camera at 105mm and under? I just got the camera and it seems to be really good--- like the good old days lol.

It should have new firmware. If it doesnt have version 1.3 you should download it from Fuji, it's supposed to function much better with that new firmware.

David, out of hundreds of posts I've read about the HF 200, yours is by far the most helpful. I am shooting a corporate board meeting in poor flourescent lighting tomorrow, and trying to get test to get the best results. The meeting is 90 minutes long, so I am going to try to break it up into approx 20 min segments while shooting for easier file management. Going to shoot in FXP mode 30p. I am going to try some tests with aperture priority at wide open. Are there concerns about subject staying in focus by doing this, or is the autofocus reliable enough for shallow dof?

I would assume you could. I can shoot in full daylight with my little Sony, in NighShot mode, with a 720nm, near infrared, filter in place. I can't see through the filter but the camera can, and with the filter in place they are truly IR images. The images are really quite pretty, the sky goes black and the foliage goes white. Having said all this Paul is correct, you can't get thermal from this camera.

I believe daylight is 70'. I do not believe it will zoom, but the quality of picture is high enough that you can digitally zoom (crop and bring it up) if you have any photo editing software. I have seen no noticeable loss of quality when I have done that. I also have a Reconyx HC 600, but it is no better than the 500. I guess if you have spooky deer, the 600 doesn't even have the dim red glow of the flash in the 500. I get just as many night shots with either one, and have never seen a sign a buck shied from a dim red flash.

This is a very nice camera and has a built in light density sensor. The sensor gauges the level of light to prevent red eyes from occurring. I have had this model dslr for several months and have enjoyed every photo shoot. The quality images and ael zoom are fantastic! Good Luck! There are 2 main focal switches on the camera. AF /MF on e on the body of the camera and the other on the lense. Be sure that both are set according to how you would like for the image to be captured. Adjusting images through the user interface takes a while to get used to. I hope that this information was useful.

I have the exact same question. Please do post your findings. I am confused too. Apparently 18-200 is supposed to have larger zoom but I want to make sure that the quality of 18-200 matches to 18-135 at the least upto 135 mm. If so i will go with 18-200 for sure.

If you are using the camera normally, lighting is as important as it is with any other camera. Using the infared mode, it seems to work a little better in low light than total darkness as the infared (on my camera at least) is not very strong. You get about 5-6 visual at most depending on your angle in total dark where as you might get 10 to 20 feet in low light, but it may be harder to distinguish things at the greater distances.

This is an Infra-Red filter. It filters out all visible light so that the only thing the camera sees is the invisible to the human eye, infra-red wavelengths. You could use this on Black & White, or Color infra-red film, if you have any. I'm pretty sure that no one makes infra-red film anymore though, so you might have a problem there.

Well this is a full spectrum camera so you would need to block all visible light with a ir filter unless ur in a location that is pitch black, but this camera has a fixed focal length and no optical zoom just digital, so I would not recommend this cam for anything that may be at a distance, maybe the Bell and Howell DNV16HDZ-BKFull 1080p HD 16MP Infrared Night might be better..... it has 10x optical zoom but is a ir cam not full spectrum. Both would need ir filter tho if u want to capture pure ir image only with no visible light. The bell uses 37mm filter this one is a 34mm.

This camera does very well in low light, but it is not IR. Infra Red cameras can see people in pitch black, so perhaps find a "Foscam" one if you really need it.

As trivial as it may seem, don't skimp on a filter. You have a nice camera, so get a MULTI-COATED filter from someone like B&W, Heliopan, or Hoya. The multi-coatings reduce flare and reflections, just like your multi-coated Nikon lens -- again, don't skimp, it'll truly reduce the quality of your photo's especially in sunlight. The size of the filter should be imprinted on the lens, and yes, it's 67mm. A good filter is somewhere in the $50 neighborhood.

I don't see it because it does not happen with the kind of photography I'm into. If you like using 8-10 stop ND filters to do long exposures in daylight, or like to open your aperture all the way and point directly at the sun, then you will have issues with it. It will not affect most users in normal practical situations.

You need a filter that passes infrared light and blocks much of the visible light or you will just get normal B&W; shots. I've used a Cokin 007 filter, which is equivalent to an 89B. This is a very dark filter; you get more of an IR effect with filters that block more visible light. This is not a true IR film so the effect won't be as extreme, but you can still get some good shots with light leaves and dark skies.

No, the 24-105 will take a 77mm filter. I actually have a tiffen filter on my 24-105, it works fine, but you will get ghosting, or lens flare from time to time, just watch how closely you shoot to any lights and you will be fine.

Mine only decreased approx. 1/2 stop of light. Using Nikon D3200 body with Rikenon 50mm 1.7 lens. Quality was not 'degraded', thought images are a tad softer.

Essentially, almost all cameras can be converted to taking Infra-red pictures. This is done by replacing the sensor and internal filters. Some work better than others, and some lenses work well and others are horrid. Your best bet is to contact one of the several companies that do IR conversions and have a dialog. BTW, once you convert a camera to IR you can still take regular pictures, you just have to convert the camera back!

with one of the filters on you can only zoom about half of your full zoom. Also if you don't zoom enough you will see the circle of the adapter until you zoom out far enough.
