NOTHING ELSE changes!!! absolutely NOTHING. I don't get what your problem is.. the mm amount on the lens is what matters... if you only get a 1.6x crop out of the resulting image in comparison to a full 35mm frame has no relevance to the lens.
THE MILLIMETER OF THE ACTUAL FOCAL LENGTH ARE ALWAYS THE SAME!
end of story.
A canon 55-200 EF-s and a 70-200L lens at 200mm on a canon 7D will produce the exact same image...the same as if you would mount both lenses on a full frame body and crop the image by 1.6.
end of this meaningless discussion now.. geez

How can something like this be for "some phones?" Doesn't make much sense to me--seems more likely to be a problem with the carrier--mine did fine figuring out it was now daylight savings time. :confused:
Is it possible that 4.2.6 and 4.3 have different DST settings? Sure. Unlikely? You bet. Odds are we're seeing an issue with carriers and it localized in spots.

I think I deleted/edited all the pages and categories you mentioned that you didn't have permission to change.
Thanks
I moved the Forum Posts category into the Mac Guides category. I don't think it deserves to be listed on the main page since it's more a secondary categorisation of articles and not generally a logical place to look for something.
That sounds sensible.
Some brief comments on the Guides category since I'm not sure everyone fully understands its purpose; it contains 'how to'-type articles as opposed to encyclopaedia-type articles, so it's not just a catch-all. Having said that, it might not be the most logical categorisation structure so I'm not completely against removing it.
I've been doing some changes, but I'll stop on this one for now. The problem with the guides category as it stands is that a lot of the articles should be somewhere else as well or just somewhere else. I think the best way forward is to give every article in it another category unless it really isn't appropriate and then go and recover any articles that are actually tips like that.
It'll need need a bit more work, but it'll make sure nothing is missed.
The new Mac Hardware/Macs categorisation seems strange. Having the extra step of having to go to the "Macs" category after going to the "Mac Hardware" category seems unnecessary and could make hardware articles hard to find.
I think you're right. Maybe its worth bringing the main articles into Mac Hardware and keeping the G3-G5 Macs in a category called G3 to G5 Macs or something.

Much easier said then done. Remember, it takes 60 votes to get anything done in the Senate and the Republicans obstructed virtually ever bill brought up.

No you will not.
Edit: to clarify, if you take an EF 17-40mm and put it on a 60D, you will get the exact same field of view as an EF-S 17-55mm if both are set to 17mm.
Well, no, you will not. You are not using the FULL image circle on the EF lens on the 60D. Take that same EF 17-40 and put it on a 5D and your image will be composed differently. NOTE: the Lens has not changed it's focal length, but your image HAS changed.
The common misconception is that your field of view is what the CAMERA records. In actuality, it is what the LENS TRANSMITS to the camera. Since your 1.6 crop camera does not utilize the FULL lens image circle on an EF lens, it has the effect of zooming the transmitted image. SO your 17mm is not 17mm on a crop camera, it is the equivalent of a 27.2mm (28mm) EF-S lens. 17 x 1.6 = 27.2. On a 1D camera, that same 17mm is the equivalent of 22.1mm, where a 5D as a FULL FRAME camera is using the full image circle from the EF lens, so it is a true 17mm.

We just need a new chip - g5, power4, what ever. We need a chip that can go head to head against the Wintel world and not rely on 2 processors to try and keep up (and even now, this isn't working)
Its very frustrating and I hope Apple will all make us happy sometime soon.

... sooo, a thermocouple (http://en.wikipedia.org/wiki/Thermocouple) on a chip? Thermocouples have horrendous efficiency. I don't see how a such a chip in an enclosed environment (like a laptop motherboard) can achieve enough of a thermal gradient to produce enough current to be useful.
I dunno, i'm skeptical.
Skeptical you should be, but these aren't really thermocouples. The same physical principle applies, but thermocouples are really only for temperature measurement. These are thermoelectric coolers. See here (http://en.wikipedia.org/wiki/Peltier-Seebeck_effect).
If you want to power the temperature change yourself, you need a high current. But if you want to generate electricity from them, then just connect them into a circuit with out any powersupply i.e. stick a fan's power terminals on that, stick one side of the TEC on a hot chip or cup of tea etc. to setup the delta T. (temp difference) then the fan will start spinning!
Dan :-)
While what you're saying is true in principle, I seriously doubt the practicality of what you're suggesting. TECs are moderately efficient at converting electricity into a temperature differential (or being used as a heat pump), but their efficiency in the other mode of operation (Seebeck effect) is very, very low (typ. < 5%). If you take a chip-sized (~ 1 cm^2) TEC, connect it between a hot processor core at 100 C and ambient temperature at 25 C, you will not have enough power to turn a computer fan at any modest speed. Furthermore, even if you could harvest that electricity and store it, the added energy would be less than 0.1% of a typical laptop battery. :rolleyes:
If you wanted to use a larger TEC module (say 16 cm^2) on top of the 80 C CPU case, then the added energy would be less than 1%.
Estimates based on info here (http://www.ferrotec.com/technology/thermoelectric/thermalRef13.php).

As far as Nikon goes: The reason was the F- Mount.. High speed crop is a byproduct. the D700 does not have it and some other don't either but they all MOUNT DX lenses in crop mode AND full frame mode.
The term high speed crop was specific to the D2X. If you reduced the capture area to around 5Mpx, the frame rate increased from 4-5 FPS to 8 FPS. All of the Nikon FX bodies have a setting on the Image Setting menu called Image Area that governs whether the body automatically crops an image if it detects that a DX lens is mounted to the camera.
The only DX lens I had was the 17-55 and I sold it a few years ago when I replaced it with the 14-24 and 24-70.
