Upgrade to the 7D and sell my 50D??

[Cytoman]

You posed your question to many people with an obsession. Take out a loan, and get as many primes as you can possibly buy, and a couple of 1D series cameras body's. You always should have a backup.

Thanks. I still have a lot to learn about equipment, and a lot of money to spend.

with current interest rate as low as 3.75% for 15Y fixed,and weaker dollar, maybe it's not a bad idea to cash out some money to "invest" in "L" glasses[:P]

<span style="font-family: Verdana, sans-serif;"]Honestly, I am surprised.<span style="mso-spacerun:yes;"] [img]/emoticons/emotion-3.gif[/img] I expected the 7D to win hands down. I knew glass was important, but I didn't expect it potentially trump an upgrade to the 7D.

Well, it sounds like you have a solid plan now, or at least a lot to think about.


Lets take a look at the Image Chain for a moment. Since you can't gain quality, the best you could hope for, is to retain quality, and even that is a stretch. That means that you have to start out with the best possible image and then transfer that image to the sensor unharmed.


In that regards, light is the most important part of the chain in obtaining the image. Lets face it, without any light (either natural or artificial) there's no photo.


The next most important thing in the chain, is probably the filter. If you have a low quality filter transmitting distortion to an expensive lens, the result will be poor image quality.


If I smear mayonaise on the front of the filter and I have a $5000 body, the picture will be terrible. If you have inferior optics inside the Lens, the picture quality transmitted to the sensor will also be poor.


A good quality sensor is next in line, in order to capture the image.


So, basically, you need to start off with the best image possible in order to have a chance of recording that image properly. That's why a lot of people say, "glass before body." You know the saying, Garbage In Garbage Out.


I'm not even going to attempt to get into other factors like; Auto Focusing, Diffraction, Camera Shake, and IS, but certainly it all matters.


Neuro's right regarding indoor sports for kids, since most Jr. High School and High School Gym's are poorly lit. You will really need an aperture of at least f/2 which will let in twice as much light as f/2.8, in order to achieve a fast enough shutter speed of at least 1/500sec, so that you may limit motion blur and image noise. Again.., depending on the lighting in the Gym, with an aperture of f/2.8 you could take still shots, bench shots, candids, and blurry action photos.


See, it always comes back to light!


"Basically.., the acquisition of light is expensive."

On line price for the 7d without the lens $1539 andcanon offersa $400 or $500 rebate for the pixma 9000 or 9500. The 9000 sells for $499 so you end up with $99 bucks in the printer. With the lens it the 7d is $1799.


I think he is overpriced for the used camera, concidering the rebates offered. Maybee take the memory cards in to concideration. If they are expensive fast cards then that would help, cheap cards not as much.


Take the majoritys advice here, I think for quality of pictures go with the glass first.
