Thinking of upgrading from film SLR to digital SLR
Here's the rub..

-I have a Canon Rebel 2000 which I bought about 8 years ago along with 2 Sigma lenses. (28-80 w/Macro mode and 100-300) I know Fstop information can be useful, since neither of those lenses are in production anymore, but I don't remember. I do have the original boxes, but not with me, they are stored..

Here is what I am wondering:.

1. Will I still be able to use those lenses on a new Canon DSLR or will I need to buy new?.

2. I read about the zoom factorization when using a SLR lens designed for film with a Digital sensor, I heard, however, that some cameras do have a 35mm digital sensor to defeat this issue. Is this a practical solution (>$2000 = not practical) or still way too expensive (the only camera I know with this feature is $8000, not practical for me).

3. I was wondering about how many photos does it take to burn out a 1 GB flash card? 10,000? 100,000? An order of magnitude is fine..

Thanks..

You probably get better practical info from the Canon lens forum..

5D is not that expensive anymore..

Depends heavily (jpg/RAW) on the size of the image file: about 50-500..

As a point of clarification, when I said "burn out" I meant "render useless, in a state unable to store additional photos ever, similar to sticking the memory card in a fire for 20 minutes and trying to save images on it". I did not mean how many photos it can hold before needing to be dumped to a computer..

Thanks though .

Probably but some Sigma lenses need to be rechipped. Effective focal length will be increased by a factor of 1.6 except on full frame bodies - see below..

Full frame cameras are expensive and really need good quality lenses. You would be better off buying a 1.6x crop factor body (e.g. 1000D, 450D, 40D) and getting something like an 18-55 IS lens as a replacement for the 28-80..

You 100-300 may not be a very good lens and you could consider getting complete new kit. This would mean that you weren't restricted to Canon..

Were you thinking of using memory cards rather than a hard drive for the long term storage of images?.

Well, you can have a nice fire from 50-500 pictures in paper. .

I can't comment on the lenses because I don't shoot Canon but as far as the memory card I have never had one totally fail. I'm sure it happens but I have shot thousands of of shots..

From an electronics standpoint there is no limit on the use. Any electronic component will break down over time but it's a very very long time if it is made properly. Buy good quality brand name memory cards and they will probably be able to be passed on in your will..

And avoid really really big magnets!!.

1) Some older sigma lenses need to be upgraded. Sorry, don't know the details. Try canon forum or email sigma..

2) Practical is always relative. A canon 5D is about $2000. Alternatively, buy a digital rebel and a canon 10-22mm or sigma 12-24mm to retain wide angle. (Or start fresh with the make of your choice - nikon, pentax, etc.).

3) Although flash memory starts corrupting after a certain number of writes (can't find the figure for you at the moment - in the 100s of thousands), the overall card life is extended by wear levelling and by the filing system mapping out bad memory locations. (Of course, at the time an error first appears, you might loose some images.) I think other factors are more important, like build quality of the card. You would statistically wear out your camera shutter before you would burn out a memory card..

There we go. Thanks for the info about the memory cards and lenses. That's what I needed to know..

As of now, I deem all questions answered.

Any decent quality memory card used in cameras should be able to be written over millions of times..
