Opinion: This is a great point and shoot camera and the image quality is fantastic. It has a good macro mode for closeups and the 3x zoom lens works great.
Problems: AA batteries don't last long. You need to keep a spare set handy.
Opinion: I've had mine as a notebook and for family snaps for over 18 months. It's OK for my purposes but found battery life poor. Only selected this due manual features but can be a pain to set exactly as required. As said, for my purposes works tolerably well but would not recommend for anyone seeking a camera to produce quality results.
Problems: Poor battery life (all sorts) as camera does seem to drain. Often have to activate and close a couple of times to get camera working at all.
Opinion: I've had my A85 for a bit over 12 months and 8000 images, the manual controls are great and the buttons are very well laid out. Sturdy construction, mine's been dropped on concrete a few times and all that it's got to show for it is a slightly loose zoom control and a few scratches. When it exposes properly the images are sharp, but a little undersaturated (I leave the camera in Vibrant effect mode all the time). Overall, not a bad camera, and I've taken some fantastic photos with it.
Problems: - Visible noise at 100 ISO, extreme noise at 200 and 400 ISO
- Resets custom settings when left in AUTO mode
- LCD screen has far too much contrast, makes checking exposure difficult
- Overexposes regularly, and its overexposed images look absolutely horrible
- Viewfinder is very innacurate at close to mid range
- Can be slow to focus.
Opinion: The A85 would've been an excellent digital camera if not for one thing: the 3rd-party sensor in it is of inferior quality and doesn't do justice to the high quality lens. Situations that don't stress the sensor too much (bright light etc) can produce excellent pictures owing to the quality of the lens, but these are a minority. A large majority of pictures will hit the sensor's deficiencies time and time again, unless you live in a very sunny country.
The camera's positives include:
++ truly excellent lens, better than in some other brands' expensive P&Ss
++ easy and comprehensive controls and menus with cutomisable sound effects
++ manual options are present
++ good mono sound recording and playback
++ high quality PAL/NTSC television output
++ can be remote-controlled from the computer
++ fairly strong flash
++ excellent macro mode, can even focus on a large enough ant
++ purple fringing is never a problem
++ firmware doesn't damage pictures with excessive post-processing like other brands' cameras do, except some hue modification. "Sharpening" filtering seems to be absent, which is good
++ long battery life, I've never had AA rechargables run out
++ feels solid, good shape
Problems: Negatives:
-- small sensor means most images are plagued by heavy to brutal noise unless the lighting conditions are bright enough to allow the sensor a low-stress situation. This drastically reduces image quality in most circumstances. Indoor shots can come out nasty. To be fair, it is not as bad as with some other cameras like the A400 and C300.
-- ISO 100 is heavily noisy in most circumstances, ISO 200 & above are mostly hopeless. Being limited to very low ISOs reduces the viable shutter speeds which is a big disadvantage
-- focus speed and shutter lag worse than desirable but not too bad (2004 camera afterall)
-- flash strength autojudgement isn't very acurate sometimes
-- up to 3/5ths of pictures are mildy overexposed; firmware has a bias toward bright pictures at the expense of shutter speed, but easily circumvented by using "Program" mode
-- autofocus has a slightly excessive bias toward narrow depth of fields, as if every picture is of a person or pet
-- movie mode more limited than it should be
-- sold as the "A85" as if it's an upgrade to the A80; it isn't, the A80 has a much better sensor. Most shots with the A85 are probably lower quality than with the A75, even though the two are identical except the A75 has a 3.3mp sensor; the A75's sensor isn't as overstressed.
-- physically heavy, not suitable for carrying around
-- viewfinder way off except on distance shots
-- saved settings randomly reset themselves to factory defaults every so often (known Powershot problem)
-- puzzlingly only allows date stamps on photos saved at 2mp 1600x1200 resolution
-- shutter needs alot of effort to press down, enough to cause camera-shake
Opinion: I have this camera by 6 months.
IMHO total auto mode is really bad but manual modes rocks!
Very sharp pictures, easy of use, wonderful colors.
I work almost always in "T" mode and it works perfectly.
Need very much light to work and the flash is Kinda small.
The batteries work for very much time.
My global evalutation is positive, for the money it costs.
Problems: Total auto mode is bad, AIAF points always where you do NOT want to focus.
Opinion: Of course Features and Image Quality are "5" for the price and the class. The main things to note are perfectly working Auto mode (which makes the camera really easy to use), smooth pictures and virtually no red-eye problem. AF and Auto WB are also good enough.
Highly recommended as a pocket camera.
Opinion: I like the image quality and simplicity of use of this camera, whilst still allowing full manual control. Very good value for money.
It is more rugged than you'd imagine. My first major outing took the camera up some Scottish mountains in winter. The camera coped well with the low temperatures, and snow and ice being blown into the lens mechanism (and then melting). I was even able to operate the camera with thick mittens on.
Problems: The size. Canon's specs say that this camera is 32mm thick. This is very misleading. The maximun overall depth is actually 45mm. 32mm is the thickness of the body, excluding the protrusions such as the handgrip.
The misleading figure of 32mm is repeated blindly on lots of websites. I have complained to Canon and to dpreview.com that the figure is misleading - so far with no result.
The camera is small enough to fit into a (large) pocket, but the way that the handgrip protudes often makes it awkward to get out quickly. This, combined with the fairly slow startup-time means that I've often missed a shot when the action is unfolding quickly.
(This is my first digital camera, so some of the following may apply equally to other cameras.)
The display is almost impossible to see in sunlight. This means that many of the clever features of the camera become awkward to access when outdoors.
The battery life is long, but they give out with no warning (there's no charge remaining indicator).
The delay between pressing the shutter and taking the picture is quite long, so its easy to miss the action in a fast moving situation. You can half-press the shutter, to pre-set the focus and exposure, but its not always easy to maintain just the right amount of pressure on the button to remain in this mode for long, and in low light the auto focus lamp will remain on - which is not much good for unobtrusiveness. Would be good to have a focus/exposure lock which did NOT rely on keeping a button held down.
Sometimes over-exposes by 1.5 stops when using the self-timer.
Opinion: I bought A85 from Walmart at only CND257. Good features but pictures are too noisy. Returned to walmart.
Opinion: Impressão geral muito boa. O software de manipulação e os recursos são ótimos. O visor LCD grande é muito útil (principalmente para quem já usou aqueles de 1.5"). Várias vezes acabou a carga das baterias com ela ligada e não deu nenhum erro E18 (quase deixei de comprar esta excelente câmera por causa deste terrorismo que alguns outors usuários fizeram). O mesmo se aplica para a A75.
Problems: - Viewfinder mostra somente uns 75% do quadro real (na prática só dá pra usar o visor LCD).
- Aviso de carga da bateria baixa só aparece quando a carga já praticamente acabou (não tem indicador permanente da carga).
- Com zoom digital a imagem no visor LCD fica muito ruim.
- Permite zoom digital máximo mesmo nos modos de maior resolução (usando interpolação), o que pode gerar falsas expectativas. Na minha opinião só deveria admitir zoom digital nos modos de menor resolução, usando a capacidade ociosa do CCD.
