robbieduncan is right-on with his explanation, you're making incorrect claims: focal lengths are independent of the size of the sensor, a 50 mm lens will be a 50 mm lens on a medium format body, a full frame analog body or an APS-C-sized dslr. What changes is the field of view, which is an angle. It is this angle which is different on the above-mentioned cameras. The reason why people write something to the effect `a 50 mm lens on a crop body is equivalent to 75~80 mm lens on a full frame body' is that we've gotten used to associating focal lengths on 35 mm bodies to FOVs. Sort of like Americans got used to measuring distances in miles rather than kilometers.
which is why I have not made the claim that 200mm on one lens is not equal to 200mm on the other (by actual measurements). What I have claimed is that the EFFECTIVE (perceived) focal length is different, when angle is taken into effect (the size of the sensor in relation to the size of the rear element).
YOU WILL GET DIFFERENT IMAGES IF YOU USE A 200mm EF Lens on a 7D (APS-C) and a 200mm EF-S lens on that same camera due to the FOVCF. on the EF lens, the 200mm assumes you are using the ENTIRE image circle of the lens, which you are not. You ARE using the ENTIRE image circle on the EF-S lens, which is a True 200mm for that camera. You have to use the ENTIRE image circle to get a true measure of the focal length. when you use only a portion of that image circle, you have to apply the FOVCF to get the EFFECTIVE focal length.
Your last 2 sentences actually prove my point for me. Everything in today's photography arsenal (at least in DSLR) is based on the old film standard of 35mm image recording space (or sensor size). It is you standard of measure. It has not changed with Digital. This is why we have conversion factors and have to talk of EFFECTIVE focal lengths.

I just got the 32GB wi-fi only version for $399 but now I regret it, I wish I would have purchased the 16GB 3G version from AT&T for $429. I think connectivity is more important....oh well, I can live with it!

Here's my take. Jobs/Apple has some dirt on Google or Eric. Is black mailing to use it if Google doesn't do what they want. But Google won't help Apple if they leak the dirt. Job's says... "They're (public or press) is going to see it all eventually (meaning the truth is going to come out eventually) so who cares how they get (i.e. how they find out.)

That's not all people do. They spend just as much effort trashing Apple.

From the talks I've had with people from the Apple Professional Services group Apple feels that real world use of OS X server is very limited. Most of their work is integrating Active Directory with Open Directory. They see most of their customers using OS X Server as the authentication, group policy, and file servers for the mac units in their customer's businesses.

I'm sure that nearly a year of wear on the edge of the black iPhone won't account for a tenth of a millimeter difference. :rolleyes:
When I first got my iPhone I found the edges too sharp and uncomfortable, now it feels great. Then again I probably just had more Kool-Aid. :p

mcrain should post his stuff on how raising taxes increase economy.
I would post it myself but I deleted the PM a last week by mistake when I was cleaning out my inbox.
I will say it was a great read and I agree with it.
We do need to raises taxes as right now they are at record lows and clearly THEY ARE NOT WORKING. Instead due to the record lows things are getting worse and more things are having to be cut. On top of that most of these stats were warned years prior that if they cut those taxes that in a few years it will come back to hurt them big time. This was made worse by economic downturn and so budget shortfalls were even worse than what was projected.
All service cut do is hurt 90% of the people for the top 5% of the income earns that they help.
If you look at most of the tax cuts they are only for the top earners. Main street gets nothing but services cut. Tax cuts never effect them. GOP screams Tax cuts tax cuts but then you look at it the cuts do not help most of us. Instead they only hurt us.
Also a kicker. the more you make the less each dollar saved helps. Tax cut at the top means money lost in revenue for the goverement but you MIGHT see 5-10% of that saved money go back into the economy. Most of it goes no were.
Compared to tax cuts or service increase on the middle class and down you will see most of that money go back into the economy.
Tell me if you want to boost the economy were do you put the injection. At the top were you might get 10% of it back or at the bottom were you will see nearly 100% of it back.
GOP wants you to believe that it is at the top. Reality is that it should go at the bottom.

I am currently deciding whether to buy a 360 Slim or a PS3 Slim. PS3 has won out for one single reason. It has an inbuilt 3D blu ray player that will be getting support for years to come. Had the 360 included a blu ray player, I would be buying it. Sorry MS.

Vocals are sort of flat and listless -- not much energy or emotion.
Otherwise, it's not really my style but you did a great job mixing it together. Thumbs up.

It would be nice if this worked in the other direction as well--i.e., from a computer to an iOS/AirPlay device. (Yes, I know about AirFoil and friends.)
EDIT: Wait, can Home Sharing in 4.3 do this? (I don't have a 4.3 device...yet.) If so, I guess I can expand my wishlist to include non-iTunes media... :)
You should check out Air Video (the iOS app). It's the best solution I've found and with iOS 4.3 it works great for streaming all the .avi and .mkv movies on my HD to my apple TV via my iPhone.
It goes (Air Video server on computer) -> iOS device -> Apple TV.
It was probably the best $2.99 I've ever spent.

Sounds a bit redundent given my Samsung TV, Sony Bluray, Humax PVR, XBox 360, Windows PC and my macs (with Twonky installed) already all play nicely together without needing a new standard.
This trend on these forums of people making posts without apparently reading the original post or any other posts in the thread before making a post is getting a little annoying.
Which of those things allows you to stream video and audio from an IOS device?
Which of those things are the least bit portable? It really seems like you spent no time trying to understand what this is and how it works before just trying to be cool-man dismissive.
It would be like someone saying "Well this new car will get 100 miles per gallon" and you saying, "Well we already got cars with four wheels, so I don't really think we need that."

This serves to highlight why someone like Steve Jobs is so important to a corporation. Most business leaders ( at least the ones I've met on planes ) suffer from an utter lack of imagination. Generally speaking they can only understand things in terms of powerpoints and spreadsheets. Its too bad because Kodak had a lot of brainpower and imagination under their roof and they didn't take advantage of it. Now it's all ex post facto and woulda coulda shoulda.

You forgot one thing. I added it for you. You're welcome.
I love how so many here talk about needed cuts, but never talk about needing to raise taxes. :rolleyes:
actually the reason I didn't add raising taxes that is that I don't think it would generate much more revenue. It might help but it wouldn't do much in comparison to just cutting waste. Also I think that atm a lot of businesses would just give up if they had taxes raised.
But the thing is the US economy will collapse no matter what happens. After the collapse it would definitely be better if there was a low tax/low government spending environment.
What we need to do is GET RID OF THE FEDERAL RESERVE and IRS.. thats what we need to get rid of and bring the jobs back from India.. We also need to take complete control of the banks and corporations - power to the people.. or freedom, something this country does not have at present.
Errr so the government would control the corporations. Honestly I would leave to go and live in india if my government did that. Getting rid of the FED and the IRS would be nice though!

Just in case the stealth mission doesn't work call up some Somali pirates for back up.
I'll be in the elevator with said midget, make that a snappier elevator, to allow for quick transport to the hull of the ship. Once in the storage area we can grab the 2011 iMacs and perhaps a few white Jesus phones ;)
Edit:The midget was in the old thread, he needs to appear without warning, much like the silent update for the magic trackpad!

I'm sure that this works for a lot of people, but not me.
I travel frequently in the Adirondacks where there NO AT&T service, not even Edge. The whole concept of the ADK region is for it to remain pristine forest and mountain, unspoiled by cell towers. That concept isn't going to change without a NYS Constitutional Amendment, and that is not going to happen in our lifetime.
I think the whole point of having GPS on the iPhone is to be able to get maps as needed. Garmin is missed the boat.
