no manufacturer uses effective focal lengths to refer to lenses for dslrs (e. g. it's a 17-55 mm f/2.8 lens and not a 27-88 mm f/2.8 (equiv.) lens), be it a lens tailored for crop lenses or otherwise, but always the physical focal length.
Correct. Your lens is based in 35mm terms. So by utilizing a less than 35mm sensor'd camera, you are not using the full 35mm image being projected which is where this 1.6 factor comes into play.
Where RobbieDuncan is missing the boat, and most that are arguing incorrectly is that the image will be the same using an EF lens on either a 1.6 sensor'd camera or a FF sensor'd camera. The end result is that it will not. Focal length of the lens has not changed, but your image has.
For the EF-S lenses, since the rear element is smaller, your image circle is smaller, and is tailored to the 1.6 sensors... agreed? Ok. How can this now apply to 35mm? you don't have a full 35mm image circle projected through the lens. So apply your FOVCF to the actual focal length and you will get a hypothetical, imaginary number that equated to 35mm. But since your lens elements cant transmit a full 35mm image, then the argument goes out the window.
What does happen, as indicated by the linked image earlier whereby the 5D was modified to accept an EF-S lens, the image is not complete. Not enough image is sent through the optics of the lens. This shows exactly what my argument has been all along.... the image will be different. What a 1.6 camera is doing is taking that sample image, but only recording the center of it. So, Effectively, it is a zoomed image. So the Effective Focal Length for that image is bigger... say 50mm, where the lens may have been an EF-S 35mm.

It has the underpinnings of a great program. The UI is a little unfriendly and could be more intuitive. Hopefully it progresses faster than .Mac has in improving.

Classic B&W mountain photography is probably my favorite of all time. I can just stare at Bradford Washburn's photos for days. I think you did really well here and I enjoyed this one for sure. My only complaint is that the right side left me wanting more, like we weren't quite finished with the ridge.

It's pretty clear that the lens is in a deeper "well" in the white model. This is consistent with the rumor that light was impinging on the camera in the white model. What you need to do is limit all light that isn't coming from directly in front of the lens. No light from the side, and definitely no light from the inside of the camera. The way to fight it if you have an SLR? Invest in an old fashioned thing called a bellows, which shields the lens from any light that isn't coming from the area you can focus on, and which doesn't do anything but add glare or make blacks in the picture more like dark gray. This deeper camera acts like a bellows, I presume, blocking any light coming through the white, more translucent body.
I believe that's also what the little aluminum trim ring around the camera sensor is used for too to block out the light from the translucent body and the LED flash. The prototype iPhone 4 never had that ring I believe.

I actually find it amusing how much time you've spent making a big deal out of nothing here. But whatever puts the wind in your sails.
Again I find myself repeating what I've said already, but that's no more time than you and your man have arguing your point.

LoL they made 30billion of cuts. Ten times that wouldn't even be enough to save the US economy from absolute ruin. The Democrats are completely clueless as to the danger america is facing and even the republicans think it can be fixed by 60 billion.
The debt ceiling is the last stand for america's economy. If it is raised the total collapse of the US economy is set in stone and it will only be a matter of time.

i dont know anybody who is upgrading !
in fact they all wait for the universal binaries
It's a chicken & the egg problem: no one will by intel macs until universal binaries come out and universal binaries won't come out until more people have intel macs. However, I think I'll upgrade to either a Mac Pro or MacBook Pro after Apple releases Leopard since I don't really use anything that needs to be a universal binary. Maybe xCode, but that's already universal. Anything else, I don't mind running under Rosetta.

Anybody remember when WalMart advertised that the products they sold were "Made in the USA"? Sad time my friends, sad times.
Funny story on that.
The small town where I grew up had a Western Auto store. It was the place to buy all kind's of stuff, including bicycles. My family was friends with the family that owned the store, I heard this tale from the father.
After WalMart opened in our town, sales at the Western Auto slowed. The guy went down to WalMart to check out what they were doing. He found the same brand of bike he was selling, being retailed at 1-2% more than was paying for them. The next time the bike manufacturers rep came by, he asked him about this.
"Well", the sales rep said, "volume discount this, economies of scale that, efficiency the other".
"But my families store has been supporting your brand for 40 years, where's the loyalty?", or words to that effect.
"Well, times change", was the answer.
A year goes by, and the bike manufacturer rep is back at the WA, where he sees a good assortment his brands bike, including new models just released the previous month. He goes to the store owner and asks him "Where did you get these new bikes? You haven't place an order with us in 8 months"
"I bought them at WalMart".
"Why would you do that? You can get them cheaper by buying them direct"
"Not a lot cheaper I couldn't. And I figure either WalMart is selling them for no profit, or you are. So by buying them at WalMart, I'm *********g one of you sons of bitches, and that makes me happy!"
Moral of the story? The bike manufacturer moved their production facilities over seas. The Western Auto is now a Beef O'Brady's.

I haven't ever been under general anesthesia per se, but for having my wisdom teeth out about 3 weeks ago I was sedated by IV injection with Diprivan (basically the same thing as a general anesthesia from my perspective -- I was out). An hour beforehand I had taken Ativan as a tranquilizer and during the operation I was given three shots, one of which was Demerol (pain killer) and I think one of the others was Valium. I didn't really perceive anything much that I remember until a while after the surgery -- though third-party accounts indicate that halfway home from the oral surgeon I was able to finally determine that I was in a car on Dodge Street -- but the amnesia effect of the Diprivan was pretty strong (there may have been Versed, I don't know). I do however very vaguely -- almost like a distant dream -- remember waking up after the surgery and telling the nurse I wasn't ready to leave recovery yet.
Basically it's like nothing at all -- my tranquilized self got into a dental chair, the doctor stuck a butterfly-type IV in my right elbow, and hooked up a syringe of white liquid. I asked what was in the IV, the nurse said it was Diprivan, and I felt myself fade out.
Obviously back surgery under general anesthesia will be different from oral surgery under conscious sedation, but I've shared my experience FWIW.

hmmm... PA Semi's previous military contracts might have to do with this as well.
Any conspiracy theories? lol

There have been many intel gpu based machine that had 1600x900 res displays, like the C2D Vaio Z or some of the offerings from Lenovo. I don't see why apple can't give such a res with to the 11.6in MBA with a 350nit display and wide color gamut. Then just add and SD card slot, make the usb ports 3.0 and a maybe even add a thunderbolt port and I'd be the first in line to get one.
Core 2 Duo based VAIO Z's had an NVIDIA graphics chip for light gaming/HD videos/GPU intensive processes and the Intel graphics were only for basic processes like Word and internet surfing.
In the Air you would be stuck with the Intel gfx doing everything as there is no space for a dedicated chip.

It's a great Word alternative for those who don't need Excel and don't want to shell out several hundred bucks (MS Office) just to get something better than TextEdit.
At $80 for iWork and $150 for the student/teacher edition of Office, it's a bit harder to justify. Of course, if you get an academic discount, $50 for iWork is low enough that you might just pick up both. I'm waiting for Pages to become a more capable page layout app. I'm still a little worried that Apple won't stick with it.

i bet they had people there with MBA's from good schools running financial what if's and telling management to avoid digital because they will make less money due to not selling the film or anything other than the camera
Don't know who said it, but "if you don't cannibalise your products, someone else will". Which is exactly what happened to Kodak.
Greedy or not, if Apple and RIM are part of some patent infringement they have to pay up.
First, there is an "if" in that statement. Second, they wouldn't have to pay what Kodak demands, but actual damages. Third, Kodak has a market caps of $944 million, so if Apple and/or RIM thought there was any danger they have to pay $1bn, they would buy the company. Apparently they don't.

I can see this.
Take me and my gf- she works soon I'll have finished studying and be working full time. We won't need a full computer each. Get one mini/MB/MBA and two iPads for the same price as two MBPs.
The iPad is much better for emails/web than computers in my opinion.

I am trading this guy a crappy guitar for it. I don't plan on using it, just wondering if it is something I could flip and make a profit. And the guitar has not been used since I was around 10 and I am pretty sure it is from Walmart.
Don't count on making a profit off of an iMac G3. I think at most it is worth $40. Having the box and everything is a plus, but it is still a G3. With all that said I would definitley buy it and keep. I bought one a while back in box with all the original items and box for $10!!
