Pentax vs Canon

Okay, so I like digital cameras. But I'm wondering how many megapixels you really need.

Right now, my two main cameras are Pentax Optios. My newest is a Optio S5i, 5 Megapixel. It's super compact, easy to use and takes great pictures.

I just checked and it's the same size as a pack of cigs.

Now I come across a Canon PowerShot SD550. 7.1 Megapixel.

I love the looks of it, but haven't used it yet so I can't tell how it handles. (A lot of digital cameras are difficult to focus in odd lighting situations)


But what I want to know if, are you really going to notice a difference in picture quality between a 7.1 megapixel camera and a 5.0 megapixel camera?

The quality of your pictures has little to do with the amount of pixels, but more with the quality of your lens. A 7 megapixel camera with a cheap lens will make worse pictures than a 5 megapixel camera with a quality lens.

I personally use Canon. Nothing against Pentax, just prefer the Canon range.

Mine is 2mp (yes it's old) but it still takes great shots and I'm happy with it. (Powershot A40)

Oh, and a decent optical zoom ratio as digital zoom just doesn't match up to optical zoom. - Though I suppose things are getting better as the megapixels go up.

As Ferre says, a good lense is very important and Canon & Pentax both have a good reputation for quality lenses.

BTW - Good morning guys

I actually use a Sony DSC-F828 (8.0 mp) with the Carl Zeiss lens, but I did notice a huge difference with the higher mp, especially if I was doing much cropping. I also noticed a major difference in the quality of images that I was having printed, especially the larger ones.

Here is an example of a heavily cropped pic I took this summer.

A lot less than I probably should as I come out terrible on photo's.

People always say that I look like someone from a most wanted list so I try to steer clear of them.

That's true,

The higher the mp, the bigger your photo will print or be on-screen. - 9/10 this is correct anyway.

At 2mp, my camera can't produce big photo's, just standard size.

Beautiful pic. I'd have guessed it was taken with a film camera if I didn't know better.

I take loads of pictures, it's one of my hobbies. You can see lots of them in the gallery on my website, I can recommend to have a look at all the graffiti pictures I took in Amsterdam the past years.
I use a sony camera myself (F828 ) which has a Carl Zeiss lense and an 8 megapixel imaging chip.

Carl Zeiss seems to be popular.

I think this is where it really comes down to what you plan to use the images for. Unless you need to do a lot of cropping and image editing, many lower mp cameras are fine for web use.

She's easy to take pics of because she loves to ham it up for the camera.

Today's digital cameras are incredible. Take a peek at the detail on this one which was cropped from a much larger image. For me, the best part of higher mp cameras is making poster size prints of my favorites. (That is a huge benefit for great Harley pics! )

WOW! You take incredible shots! I especially enjoyed your gallery of Amsterdam. It looks like your a natural with the camera.

When I have a camera in my hands it is like the rest of the word ceases to exist beyond what I see with the camera's eye. It is definitely one of my favorite hobbies.

Thanks Cricket, it's the result of years of photographing with all kinds of cameras, I had them all the past 25+ years. I also learned that it's not the camera that is the most important, but the lens and your own eyes to make quality pictures, that's why I stick with the sony, it does all it takes to make good pictures and I can film with it, and film has good quality too. But you know that I'm sure, you have the same camera as me.

If your not 100% sure, I think you can't go wrong with one of these: PRO Camera

I get them for free.

Speaking of which, I'm going to be selling a TON of antique/old cameras - around 50 - and wondering where would be the best place to do so. I hate eBay - too many cheapskates.

Ferre, I have looked through your gallery several times and was always impressed with the pictures, but didn't know that you had taken them.

Just a thought, how about right here on your own forum?

If you have a ton of old cameras, I guess the smartest thing to do is to make your own auction site. A friend of me makes tons doing that with glass pipes.
