I am a dermatologist looking to upgrade my camera that I use to take pictures of skin lesions. I currently have a "Canon PowerShot SD1100IS 8MP Digital Camera with 3x Optical Image Stabilized Zoom" that I purchased 2 years ago. It is an ok camera but I often struggle to get crisp macro pics of skin lesions in the often poor indoor lighting of the clinic rooms. Ultimately, I am looking for a camera that fits in my white coat pocket (excludes an SLR but camera certainly does not have to be an ultra compact) and takes precise macro pics in indoor hospital lighting without use of flash (in my experience with my camera flash makes skin lesions look artificial). I plan to use this camera exclusively for my clinic... I was thinking of getting the Canon PowerShot S90 simply because it seems to get exceptional reviews and would easily fit in my pocket though I am starting to wonder if 3.8X zoom is enough. Budget -<$500 Size -Fit in pocket of my white coat -Does not have to be ultracompact, but SLR is too big Features How many megapixels will suffice for you? -Not sure * What optical zoom will you need? (None, Standard = 3x-4x, Ultrazoom = 10x-12x) -Not sure. Do I need >4X zoom to take macro pics of skin lesions? * How important is “image quality” to you? (Rate using a scale of 1-10) -***10*** -I will be using pictures for presentations and medical journals Do you care for manual exposure modes (shutter priority, aperture priority, manual)? -Not familiar with. General Usage * What will you generally use the camera for? -Taking pictures of skin lesions in a clinic room with often poor indoor lighting. * Will you be making big prints of your photos or not? -Will be using in powerpoint presentations, but not printing Will you be shooting a lot of indoor photos or low light photos? -Indoor photos with often poor and low light hospital lighting Will you be shooting sports and/or action photos? -no Miscellaneous Are there particular brands you like or hate? -no Are there particular models you already have in mind? -Canon S90? (If applicable) Do you need any of the following special features? (Wide Angle, Image Stabilization, Weatherproof, Hotshoe, Rotating LCD) -Image stabilization?
