Canon a630 vs. Canon a640?

Question

I've been reading alot about these two cameras but i need advice on which one to get, from someone that owns one.

Answer 1

It really comes down to price. I would go with the A630 because it's the same camera but a slightly smaller sensor count. You'll save around $100, this is money you can put into getting a nice fast 150X 2gig SD card and high capacity rechargeable batteries.

Now for the money . . . personly I would highly recomend the A710 since it's got image stabilization. It's only $40 more. Image stabilization works great and is well worth the extra money. Do not be fooled in to the whole megapixel vs megapixel count, so long as you are over 6 megapixels you are fine for printing and way over kill for posting on the internet.

Answer 2

Just depends, if you want the 10MP go with the A640. Both have the same sensor, the A640 has more MPs so if money is not an issue get the A640. The A630 will take the about the same quality pictures just that you cannot blow it up the same size as the A640 but considering you probably wont be blowing it up huge its not an issue. A high speed card will not matter in these cameras just because the camera does not process that fast in the first place. A regular SD card will be fine.

Answer 3

Since it comes down to pixels in this decision, here's my stock pixel answer. I'd go for more.

If you always plan to compose your pictures perfectly, you don't need a whole lot of pixels. These days, I'd say that 5 MP or even 4 MP is fine for the average snapshooter and this can be obtained without unreasonable expense. If you want to allow for cropping, which means enlarging only a portion of your image, the more pixels the better.

Imagine taking a scenic view and then noticing that the middle 20% of the photo would make an even better picture. Suppose you take a picture of a whole group of people and Aunt Clara really, really looks great in the picture, but everyone else looks lousy. If you have the pixels to work with, you can still make a decent print of Aunt Clara that she would be happy to have. If you buy an 8-to-10 MP camera and don't want to TAKE large photos, you can always set the camera to a lower file size. You can never go the other direction, though.

Unless the cost is a major issue, buy the camera with more pixels. You will never be sorry that you did, but you might one day be sorry that you didn't.

Having said all that, though, pixels are not the only measure of image quality. The sensor size is important as well as the image processing softare included in the camera. You need to read reviews if you want a critical understanding of image quality for particular cameras. Try http://www.dpreview.com/reviews/ for more information on the cameras you are considering.

Answer 4

the only difference is price and megapixels.

it comes down to how big are you going to print out your photos? anything under 11"x 16" will look great with only the 8mp, if you are going to be making a lot of posters, go for the 10mp.

just so you know, i printed out a photo, the other day, 16"x20" with my a630 and it looked great...i would do the a630.

Answer 5

if it grow to be me, out of those 2 alternatives, i could choose for the a630, it makes use of four batteries fairly than 2 whilst in comparison with the a710, .... 4 battery cameras value the flash swifter, 2-3 seconds, whilst in comparison with 7-8 seconds on 2 battery cameras... i hate waitin for flash to cost, in case you are able to stay with sluggish, then a710 of course because of the lens
