Any recommendations for how best to use an Arctic Butterfly?

Yes. The Eclipse swabs do dry out in their packaging. Use the pre-moistened ones soon after purchase.

Other things to consider would be, the setting of the focus distance limiter switch on the lens, is focus search on or off in the camera, does it focus properly at long distances with manual focus?
TexinAfrica said:I have a 5D MK III and a 430 EX II. I almost never use the flash with this gear, but with my smaller cameras (and built in pop up flash) I frequently use fill flash during the day and occasional slow sync for night pics.
I occasionally would like to use fill flash or slow sync flash with the MK III and 430 but it appears the only way is to truely go fully manual. Any tips or guidelines on how to do either without needing a light meter etc. or simply guessing??? I don't find the 430 user guide much help. Thanks..........

Canon *will* have a problem with ml if ml isn't helping their sales as a unannounced big feature but makes people not buy the 1dc. I gather Canon will make this position clear one way or another, and I hope the main ml devs will make it as clear that they do not want to cause Canon losses or profit from hacking the 1dx.
Isn't it that ML is just running beside Canon's software? It's not modifying the code or any hardware. Right? It's just like some software running inside your OS. E.g., if I make a program that runs in Windows and uses the intrinsic OS commands like showing the clock time, even hacking into memory management, does that make my program illegal? For me 1DX can be looked at as platform. Why do you think Sigma, Tokina, Tamron and Samyang were able to make those 3rd party lenses? They even had to reverse engineer the way the lens is communicating with the body. Isn't this a higher form of hacking into the system?
If I read it right, another reason why Canon is differentiating 1Dx and 1Dc is that tax laws in some countries are different for stills and movie and even the size of the output for movie cameras. Of course you can't discount the fact that they will earn more through introducing a different software for the same hardware. That's why I'm looking at ML like an open-source 3rd party software something like JAVA.![]()
I seem to remember seeing reports of issues with the ACR beta. It certainly wouldn't be the first issues with new Canon (and probably other) cameras on the first one or two updates after support was initiated, as there were issues with the last version of LR2 that was introduced immediately following release of the 7D. LR3 largely corrected the issues.LetTheRightLensIn said:tron said:DPP could not be bugged. It had similar results to Adobe software! Both produced less sharp 5D3 raw images
I know Canon even said DPP had a bug, whether that explained it all, I don't know.
Are you sure about ACR. I don't recall that.

Etienne said:5DIII ISO performance is about 0.5 stops improved over the 5DII, if you are using RAW (doesn't everybody use RAW with the 5D series?). Don't be so "uninformed."

B+W announce two new GND (grey) filters that can be used with the Cokin Z-Pro and Lee filter holder.
number 701 (- 1 stop soft)
number 702 (- 2 stop soft)
Glas with MRC sealing, 10x15 cm, delivered in a tin box
Press text:
B + W graduated neutral density filters are often used in landscape photography in order to avoid an overexposure of the sky with a correct exposure of the ground. As in overexposured areas of the picture image information is normally lost the effect of this filter can hardly be simulated by electronic image processing.
The filters are coloured neutral gray with a smooth transition into the neutral filter half. With screwed filter the rotatable mount allows an exact horizontal alignment.
The glass substrate of the B+W ND filters 701 and 702 are absolutely plane and parallel and finely polished. This guarantees a long lasting high optical quality. By means of thin layer technology the ND gradient is evaporated. The below values refer to the darkest filter glass parts:
701 +1 stop (50% transmission)
702 +2 stop (25% transmission)
The graduated ND filters are provided with a high quality MRC coating. MRC (Multi Resistant Coating) coated filters have an MC layer ensuring a high transmission and maximum anti-reflective surface. Furthermore, MRC is dirt and water repellent and makes cleaning much more easier.
