Can Lens quality be compensated for by playing wit A lot of times I hear people say that over/under exposure is easily rectified by using RAW image manipulation. I also hear people complain about the characteristic of certain lenses. If the quality of pictures that come out of a lens is good in terms of clarity, can flaws in color/contrast etc be compensated using for instance PS? and therefor save a lot of money by buying "cheaper" lenses. Thanks in advance . Bart Stoker

You can take great pictures with any camera body - it's really just a black box with a place for a lens [or a lens] and a place for the film or media card. More expensive bodies have more bells and whistles that, presumably, make a picture easier to take. But, no matter what you've heard - buy the best lenses you can afford! You have to get the best picture onto the film/card and you do this by passing light [the image]through the lens. Lots of folks will argue that you should use the lenses made by the camera manufacturer. These will cost the most. After-market manufacturers like Tamron and Sigma make pretty good lenses - these cost a lot less. Forget over/under exposure unless you're thinking about lens speed. Remember, if the image recorded is great, you're not going to make it "great" using an editing program. You may improve it to some degree, but you won't "make" it great.

John is correct. When buying a camera, buy the least expensive body that has the features you want and need. Any extra bells and whistles are just an extra expense and are often unused. However, but the best glass you can afford. A cheap lens on an expensive body won't give you near the quality a great lens on an inexpensive body will. Just consider the body as a place to mount your lenses.

Bart: Some good advice from others but you're discussing digital photography. And yes, some factors can be improved in the software. Contrast and color rendition, for example. If you use Photoshop CS or Elements 3 (with the latest RAW converter software - download from adobe.com) you can even fix vignetting. (Darkening at the corners of the image.) Problem is, cheap lenses do not produce very sharp images, and you cannot really solve that problem in the RAW converter or later. Also, optical distortion is a problem. You CAN improve both factors with some special software, available for specific camera/lens combinations from DXO Labs. http://www.dxo.com/en/photo/home/default.php The software is expensive and available only for a few lenses. http://www.dxo.com/en/photo/optics_pro/cameras_lenses.php Read the Review at http://www.luminous-landscape.com/reviews/dxo-explained.shtml Frankly, you would probably be better off buying a high quality lens, although DXO does a nice job even on images made with excellent lenses. Cheers! Peter Burian
