Default Lens Fog

Seeing as how the weather is getting colder, I thought it would do me good to figure out the best way to avoid this thorn in my side. At the Homecoming football game, this ruined about half my pictures. What are the best ways to keep your lens from fogging up?

Good topic. I don't have much experience, but I'd think keeping the lens and camera at about the same temperature as the environment you're shooting in (i.e. don't have the heat fully cranked in your car and then jump out into the freezing cold to snap a shot). Other than that, I don't know.

I did notice that the operating temp for the XT only goes down to 32F, which isn't going to do me any good in ND this winter!!!!

You can go way below that, just don't sit out there too long.

I've been down to 10F with my old Digital Rebel.

I have had the D30 out for extended amounts of time with the temps in the middle to low teens, with no noticable problems...dont believe everything you read!

In the South lens fog is mostly caused by running the AC and then jumping out into the heat and humidity. I try and keep the lens cap on for a minute or two and that has helped.

As for you guys going out and standing around in 10 degree weather, ...... to cold for me.

I think my cause was that I put the UV/Haze filter on in my nice warm house, then as the night went on, the night got pretty cold(as most tend to do). So perhaps next time I go out, I shall wait until I get out there to put the filter. Would that work?

The Manual for my XT says you should put it in a plastic bag and let it slowly get used to the outside temp............but I don't have that much time!!!

I bought my camera in June and the temp never went over 100 degrees while I was using my camera...........but now that its getting colder here in the midwest I'll have to see if it operates fine,it gets below zero quite often in January.My old camera cold operate in below zero temps but that was a digital fuji film camera.

I think it is fun, almost dangerous ya know. See if you can avoid frostbite on the fingers as it is too hard to shoot while wearing gloves. Reading Ween's comment on the 32F operating on the XT is making me re-think going to that camera. Generally, I leave the camera on the heat while in the car, then jumping out, normally way up in Minnesota it is so dry during the winter, foggint isn't a problem. When you return to the car from being outside is when you get fog.

I would seriously be surprised if any dSLR was good for temps below 32F in the tech pages in the back of the owner's manual. I can't remember what the high end temp is (100F), but I know in the summer the inside of my trunk exceeded that temp.

I would do research on different dSLRs before deciding against one because of manufacturer's reccomendation for temp range...I bet they are all very, very similar.

Yes, ween. The temp range for my 10D (metal bodied, too) is 32-108F (something around 108, but you get the point...)

Consumer electronics aren't designed to withstand cold temps, but these are more like "guidlines" kinda like the expiration date on a jug of milk...you are allowed to go over, and not be at risk.

Google is great:

Nikon D70:
Min: 32F
Max: 104F
http://reviews.cnet.com/Nikon_D70__b...-30802703.html

Canon 20D
Min: 32F
Max: 104F
http://reviews.cnet.com/Canon_EOS_20...7.html?tag=tab

Nikon D50:
Min: 32F
Max: 104F
http://www.travel-images.com/slr-nikon-d50.html

Pentex *ist DL:
Min: 32F
Max: 104F
http://www.wolfcamera.com/webapp/wcs...&bct=c13000001

I think we've found a trend. I haven't checked alot of memory cards, but the one I did run across was 32F to 100+F.

I bet any digital camera, dSLR or not, falls somewhere close to these temperatures. Check your owner's manuals. Does that mean I'm not going to shoot when it's below freezing or hot as hell? Hell no!!!

Just for grins:

Canon EOS-1D Mark II ($4000.00 pro-dSLR):
Min: 32F
Max: 113F (a whole 9 degrees more!!!!!)

I think the manufacturer's operating temps are up and up bunk...

I'd bet a paycheck that the temp min and max are decided upon mainly by the legal/warranty division, not the technical experts with the organization. Stating a min temp of 32 will get them out of a lot of situations that would otherwise be covered by a warranty. "What, sir? You were taking pictures when it was 29 outside? Well, no wonder your camera doesn't work anymore."

Exactly what I was thinking. If they can limit the temp range, it can invalidate the warranty if you go outside of it. And that's up and up bunk...
