| Adrian Warren (AdrianW) Msg: #2 April 20th 2007 01:42:04 | My suggestion - aggressively boost the contrast, and convert it to B&W. Oh, and clean your sensor ;) Top left... Clone out dot, bottom left. |

| Bob Wallace (BobTrips) Msg: #3 April 20th 2007 02:30:19 | Clean your monitor! (I can't see the spot you're talking about. Give me some distance estimates.) --- Geez. I was looking at your Rev. No wonder I couldn't find the spot. (Place embarassed face icon here.) Actually I'm pretty sure it was a bit on the lens. I got something in my camera bag and had lots of dirty lens problems on this trip. | |||||||||||||||||||||
| Adrian Warren (AdrianW) Msg: #4 April 20th 2007 02:37:03 | Could be, but it looks like sensor crud to me. Incidentally, you know I said I didn't think the 400d anti-dust was any good? Well, I cleaned it, and despite being used in sandy/dusty Morocco - it remained dust free for the entire trip. I guess there was some gunk on it left over from the manufacturing/testing process initially that the cleaning system couldn't shift. | |||||||||||||||||||||
| Justin Watson (Justin) Msg: #5 April 20th 2007 14:14:21 | I like the revision it gives the silhouette a more striking appearance. Yeah i can see the bit of dust. As for built in dust cleaners..... don't get me started. Its a pet hate of mine, i think the best is the Olympus but even then its not fantastic. A blower does a better job. | |||||||||||||||||||||
| Adrian Warren (AdrianW) Msg: #6 April 20th 2007 15:57:25 | LOL, that's why I carried a blower/Eclipse/SensorSwabs with me in Morocco. Had the locals only known, they'd have stolen that instead of the F31fd - from the prices they'd probably be more valuable out there ;) | |||||||||||||||||||||
| Bob Wallace (BobTrips) Msg: #7 April 20th 2007 17:14:44 | Don't think I posted here - I carried an Arctic Butterfly to SEA for sensor cleaning. Worked great and I didn't have to try to fly with flammable liquids. I worry about using a blower. Seems like what you are doing is "disturbing" the dust. What keeps it from settling back on the sensor? And what keeps one from sucking in some new dust and depositing it in the mirror box? | |||||||||||||||||||||
| Adrian Warren (AdrianW) Msg: #8 April 20th 2007 17:28:59 | Usually a good blower has a filter on the inlet. As for preventing dust settling - I blow the camera out when it's facing down, so any new dust would have to defy the laws of gravity ;) | |||||||||||||||||||||
| Bob Wallace (BobTrips) Msg: #9 April 20th 2007 17:45:44 | The blowers that I've seen have only one opening. Seems like dust would get sucked up against the filter and then blown away unless there's a separate intake. You must have heavy dust where you live. Ours paraglides. ;o) | |||||||||||||||||||||
| Justin Watson (Justin) Msg: #10 April 21st 2007 05:48:00 | I just find it hard to recommend a dSLR with dust removal for the fact it has it. I'm sure it will get better i just think its gimmicky. Same as people who want to buy a 28-300 lens to avoid dust.... May as well go a big zoom IMO. One thing I always do is change lenses with the camera facing down, then no dust will paraglide into the body.... i assumed everyone did this but i've seen more people who don't change lenses that way than do. | |||||||||||||||||||||
| Bob Wallace (BobTrips) Msg: #11 April 21st 2007 18:08:49 | Don't know if this is true, but let me toss it in the mix. One of the sources of sensor dusts might well be telephoto lenses. There's a good chance that they could "pump" dust into the to mirror box as they are moved back and forth. Also, the Olympus dust removal system seems to work. That doesn't seem to hold for some other systems. But most of us don't live/shoot in exceptionally dusty places and cleaning your sensor is pretty easy. Buying a camera just to get an effective dust removal system doesn't make a lot of sense to me. | |||||||||||||||||||||
| Adrian Warren (AdrianW) Msg: #12 April 23rd 2007 18:07:16 | As I say, I didn't have any dust problems with the 400d in Morocco, I was changing lenses outside, and it's a hellaciously dusty environment out there - the car was almost literally full of dust when I returned it ;) I think the problem was it was supplied with stuck on dirt ex-factory. Once I cleaned it, it stayed clean for the entire trip. So the anti-dust stuff does work, it's just not in every situation. As for lenses being dust pumps, yes and no. It depends on the design - some of the Canon L-series are sealed, and they're gasketted too, so it's unlikely they'll be a problem. If there's a huge amount of dust being sucked through, I'd expect to be settling on the inside of the lens, and I've rarely seen any evidence of that. Even my 100mm Macro, which has been in my bag for ten years, as well as going around the world with me, and a bit more besides, doesn't have any significant dust inside it. Some of the push-pull zoom designs that extend significantly would be more likely to show problems IMO, but still, it's rare that a lens gets so dusty inside that it needs cleaning - mouldy, yes, but not dusty. | |||||||||||||||||||||
