what's the best lens for my purposes???
i'd like to get a digital slr to shoot my artwork. that is all the
camera will EVER be used for. i want a lens that will suit my needs. i believe 50mm is slightly wide, is it not? so i need 55mm, and for convenience anything up to 85mm, maybe. most important is the lens have as little distortion as possible should i get ,,, 1...50mm only 2...85mm only 3...55mm-200mm zoom 4...24mm - 85mm zoom 5...18mm - 55mm zoom these are the lenses available for the canon. the problem: 50mm might be wide, yes? and because i have limited space to go back in my setup, i am worried that an 85mm will give me problems on larger paintings. and the zoom gives me my 55mm, but it is a zoom and i am concerned about distortion. the nikon lenses have roughly the same. if i am worried about distortion, BUT settle on a zoom(because of the 55mm) would a 55-200 be better than a 28-80. i'm not too cozy with the idea of a wide to telephoto format like the 28-80. btw,,,i will have absolutely ZERO need for a wide. i wish there were a 55-85. thanks |

What type of artwork? How big? What distance from the artwork will

Digital SLRs have a sensor that is not (except for a very few very high priced units) the same dimension as a frame of 35mm film. So the digital image is cropped from what a 35mm film image would be with the same lens. This crop is generally (and somewhat erroneously) called a magnification factor. I don't know what this factor would be for your particular target camera but with my Pentax camera the factor is 1.5x. This means that a 50mm lens on my camera would give the angle of view of a 75mm lens on a 35mm film camera. Thus if you recognize that the "standard" 50mm lens as the dividing line between wide and tele, to get the same image with my DSLR would require a 33 1/3mm lens. This will definately effect the next part of your question. As to 50mm being a tiny bit wide, there is no hard and fast number that is THE divider. If there is one it may be 50.12696 or some such number that isn't real practical. The difference is so slight that outside of extreme scientific useage, it makes no noticable difference. should i get ,,, 1...50mm only 2...85mm only 3...55mm-200mm zoom 4...24mm - 85mm zoom 5...18mm - 55mm zoom these are the lenses available for the canon. the problem: 50mm might be wide, yes? and because i have limited space to go back in my setup, i am worried that an 85mm will give me problems on larger paintings. and the zoom gives me my 55mm, but it is a zoom and i am concerned about distortion. the nikon lenses have roughly the same. if i am worried about distortion, BUT settle on a zoom(because of the 55mm) would a 55-200 be better than a 28-80. i'm not too cozy with the idea of a wide to telephoto format like the 28-80. btw,,,i will have absolutely ZERO need for a wide. i wish there were a 55-85. thanks Due to the crop factor I would suggest that you try the the 18-55mm zoom. This lens would include the approximate correct lens length. In general if the horizontal field of view is 40 degrees (rounded to the nearest full degree) this should be the correct lens. Hope this info helps. Randy ========== Randy Berbaum Champaign, IL I failed to add also tell us about what kind of results you want. Are you interested in trying to print out results that look as much like the original as possible to hang on your wall, or are you looking for something to help you remember what you saw. How about details? If there is some smaller portion of the art that you may want to get a close up of, you may want more telephoto and/or macro capability. How about lighting?

to be more specific about the artwork.....
they are oils. i use lamp and camera polarizers with zero glare. the oils range from small(8x8) to 40x50. i HAVE TO shoot in my studio, which is about 12x17. most of my artwork is no bigger than about 23x27, but i do an occasional 30x40. i can get back approximately 5 or 6 feet with my camera to shoot. this will accomodate a 23x27 or there abouts, no problem. i can only shoot my artwork on the width of the room. if i were to try setting up along it's length, the lamps would be too close and not at a great angle. i have been using a canon g3. at 300dpi, i can get a 5" width image. up until now, i have been using those images for my galleries to print invites,,,,,,a perfect size. but i have recently faced situations where clearly it's time to move up to the 8mp range camera(8 in fact barely gets what i need). the printers are starting to ask for 350dpi, and the magazines are asking for larger images for full page spreads. this makes my 4mp obsolete. i want a dslr because i have always felt my images were lacking in really good sharpness. manual focus on the g3 is pathetic...i would also like a split screen focus because my eyes see the focus much better with a split screen than than a prism. i'm looking at the rebel xt because of the price, which is great for the next step up. randy: you're saying a 35mm on a digital is equivalent to a 50mm standard slr. so then my concern about image distortion on a 50mm dslr is erroneous....that there will be no distortion. i can get a rebel/18-55mm. that would cover the 35mm-55mm range. dennis/frederick: i think also part of the reason is simply my desire for the manual focus. as i stated, i feel my images have been lacking sharpness, maybe on an insignificant level, but it has always bothered me nonetheless. do you think maybe the lens on the g3 was lacking, and that the zeiss or leica lenses will make up it? bugbear: what kind of software are you talking about that'll correct distortion? after what you all have said, i started looking around, and the sony and panasonic look ok too. same price as the rebel, and the sony offers a 10mp, but the panasonic offers 8. |

How do you fit something 40x50 into a studio that is 12x17?
