What do you think about the new Canon A95 ?

the quality image seems to be very average, a little bad :

I am disappointed by the quality of the images, I can see too much "purple fringing", the images are not very sharp,

the A75 and A80 seem to do a better job than A95

here you can see some sample images taken with a Canon A95 :

It seems to me that the more megapixels that are crammed onto a small CCD, the worse the image gets.

Purple fringing seems to be a major issue on small CCDs, particularly when longer focal lengths are used and when too many pixels are crammed into the CCD.

My personal opinion is that I can get better photos on lower megapixel ccds and from lower zoom cameras than from ultrazooms and high megapixel counts.

In other posts, I have noted the same dissapointment with the image quality seen in the sample images posted here at DCResource and Steve's Digicam reviews. To see the purple fringing in all its glory, see the samples at Steve's (found in link at end of the review for A95 here at DCResource).

But Rhys' comment about cramming more megapixels onto the CCD being the problem? Well, I used to think the same thing. However, the sample pictures for the 7MP S70 and the G6 are really great! Purple fringing is much less than the A95, and they have lower noise levels than most 5MP. So, I guess technology will go forward, and barriers (the noise barier at 4MP or 5MP) will be broken.

Again, campare the images on the Canon S70 with others. VERY nice.

maybe the G6 and S70 have a better optical lens than the A95 ? :confused:

it think that a95 and s70 sample pictures were taken the same day almost at the same time! and if you compare each photo u will see better image in a95, for me the only bad picture was the one you posted here(san francisco bridge). All the other pictures taken with the a95 are far better than s70. S70 has a lot of distortion A LOT!!!!!! for me its not aceptable. I prefer some purple fringe than a lot of distortion!

It feels that the S45 (4meg) camera takes better picture than a S50 (5 meg) camera too.
Should have picked up the S45 myself.

Ok, CanonManiac. Stop me now. I am about to buy either the G6 or S70 7MP Canon. But I don't want a lot of distortion either. Can you post link(s) to images of distortion that you are talking about?

Gordon's link to many A95 shots are very telling on what he was talking about on the purple fringe and low quality. Did you take a look at those?

I would be happy (somewhat dissapointed too) if you could give me examples of the distortion (as you say, A LOT!!!!!!) for the S70.

Thanks.

damn. here I was hoping to get the A95 when I saw what you said to be so very true. The purple fringing is bad.. as is the redeye.. no wonder the price for the A95 is relatively cheap for a just-released-5mp camera..

just compare the sample píctures from dcr
canon a95

s70
http://www.dcresource.com/reviews/canon/powershot_s70-review/gallery.shtml

just compare each picture and you will see the same purple fringe in both cameras.. yes EXACTLY the same... with the difference s70 pictures have a lot of distortion.

open two browsers and then open the same picture and then compare! i think is more valid to see the same picture of the same place almost at the same time to compare.

look at this two pictures at the same time and then tell me what do u think...

s70 http://www.dcresource.com/reviews/canon/powershot_s70-review/IMG_4405.JPG

image quality in both cameras is the same... purple fringe also, plus the awfull distortion of s70...
which is the advantage of buying a wide angle camera if then you have to crop all the image and get a smaller picture than a normal camera?.

regarding to the price... i think its ok... its an A series which are the "economic line". The a95 is the replacement of a80, when the a80 was released it almost had the same price... 350 to 400 u$S
the s series are 400 to 500u$s and G series even more
As someone said "too cheap to be a 5mp camera...." so with that criteria the s70 with 7mp would cost 700 u$s ????????????????????? :rolleyes:

do this... first look the picture from a95 and spot every purple fringe.. then go to s70 picture and look where a95 has the fringe and u will see that there is the SAMEE PURPLE FRINGE EXACTLY THE SAME!.
And also look that s70 are too bright... for me a95 has more vivid colors.

here is another one which we have purple fringe at his best. Look that both has identical purple fringe.

Let's face it. The G series, the S series, the A series are all point-and-shoot cameras (In my book, those that don't have interchangeable lenses, manual focus, manual zoom). IMO, purple fringing and geometry distortion are due to the optics. Most people who buy a point-and-shoot don't expect a lot of picture quality because they simply have no control over the optics.

If you are critical about picture quality, get a dSLR, then buy the best lenses that you can afford.

In the point-and-shoot world, lenses are more or less after-thought. The cost of the camera, without those optical parts, would be the major driver.

In the SLR/dSLR world, quality lenses usually cost more than the camera itself.

About the A95, Canon did not price it so low because of the poor picture quality. The price is relatively low because it's an amateur point-and-shoot. BTW, I am getting one and I don't expect a lot of quality from it for the price that I paid. Great for a picnic, and hiking camera.

Hi there,

As my username suggests, I'm a newcomer to the digital photo world.

I read alot of good articles on the A80, and when the A95 came out I decided
to give it a try.

Although I've only taken a few photos and all of them with the Auto mode
I haven't seen any of the problems that have been mentioned here. Perhaps they'll turn up the first time I take a night shot, but so far, the pictures seem very clear, sharp and the colours accurate.

I'll play with it a bit more and get back to you.

Thanks, CanonManiac for the samples of what you were talking about with the purple fringe. I agree that with in the links that you provided, the purple fringe is identical.

My favorite shots for comparison for all cameras are the Chinatown Entrance, and the Park & Bridge. For the shots that I end up taking for various places, those two tell me the most for my needs. In those shots, I believe the purple fringe is only a bit more prominent for the A95. I look at the window ledges, the lettering on the signs, etc.

I think "im_dragon" hit the nail on the head on the fact that we're really just splitting hairs. These are both point-&-shoot cameras, small CCD's, and less options to work the shot. So, maybe I was being too demanding.

As for your insistence on "graininess" for Canon's 7MP. Sorry, I just don't see it. I really do se a lot of noise in shots from many 6MP and 7MP cameras in other brands (Kodak, Pentax, Fuji), and I would have expected to see a lot in Canon's too. I am not loyal to the brand. But, I just see Canon's 7MP as being quite clear, similar to their 5MP.

Thanks,
Javair

i think a95 for the price and the image quality is the best choice.
I want to know which would be yours best choice, a95, s60, s70 or other?

In other posts, I have noted my contemplation of either the S70 or the G6. I was worried that the G6 would be a bit too much camera for the rest of my family, but I believe I will give it a try. I am now waiting for a great deal to show up at Gateway or somewhere else. I hate buying one and having it be eighty dollars less three weeks later. So, I guess part of my problem actually IS the price. So, your question about best quality for the price would be an interesting new post. What's the best quality for the best (least expensive?) price? And how do you make that question not too relative? Best quality under $???

Thanks for the discussion, CanonManiac.

Good Q, CM. I'm debating the A95 vs S60. As I see it,

A95:
$100 less
AA Batteries (and thus a better "handle")
rotating LCD

S60:
Shorter focal length (28mm vs 38mm)
Simpler button scheme
Wireless control (nice, tho' not a biggie)

Some posters on another forum were complaining about the S60 lens cover, but that isn't a universal complaint.

Most of the other specs are identical, or close to it, so I'm torn.

Anyone with a strong opinion?

Just got my camera today, and haven't taken any outdoor sunshine shots yet, but the indoor shots look great.

PRO (so far):
* love the flip out LCD, my old A20 was fixed in the back and sometimes I couldn't see what I was shooting
* The movie mode, while not feature full, is quick and easy to use, and takes decent movies. If I need better, I'll grab the DV
* LOVE the PrintDirect feature. Perfect reproduction

CON (so far):
* Menu not as intuitive as my old A20 (but with so many manual options available, how could it be easy?)
* It's hard to find the right setting for indoor shots where the flash doesn't wash out the subject (I'm betting though it's more user error, will have to just see).

Here's a few pictures so far...

Upon further review ......

leaning strongly toward the A95. Figured out that if I need the shorter focal length, the $100 that I save over the S60 can be used for a wide-angle lens. But the S60 can't be retrofitted with a rotating LCD (useful for shooting and protecting it) or AA batteries. Buttons, I can learn to deal with, and the remote, well, sometimes you get funnier pics if you don't know exactly when the shot will be taken. :)

i really dont have experience on digital cameras but... the indoor shot (living room) for me isnt so good?
i should expect more image quality in other digicams? or that shot is really good?

You might want to turn the ISO down to 50 for that indoor shot... that would help a lot with the noise.

Yea I had it out of the box for all of about 20 minutes...am getting better, and while not a good shot, for what my living room is, it's not bad. I should have qualified that with a history of my living room.

For some reason, and I have no idea why, that living room has never photographed well. Even with my 1D MarkII, it still always has some noise. I think the color of the wall just brings out the noise, but *shrug*.

I plan on spending some time with it this week really learnign about it. I spent most of the weekend firguring out why ALL my shots taken with the zoom lenses and macro lenses were looking so bad, only to find out they had the wrong collar as well as the wrong lenses...didn't know how that could happen, but it did. Ah well...they're returned, and am ordering the ones I want from Canon now...should know more then.

Not true. The S70, which I have, has substantial purple fringing. So much so, that I was shocked. I'm going to return it this week.

Also, the S70 has substantial vignetting (i.e. dark corners) at widest zoom with flash. A huge deal breaking defect IMHO.

Just a note, but on the living room thing, even the 1D makes a noisy "looking" image, but I actually am thinking it is the texture of the wall coupled with the reflection of the light off the wall. I'll try and take some comparison shots this weekend...and I still haven't gotten to the prints...argh
