Good results with Oly 4/3rds compared to Canon EF lenses?

People who have worked with film in a variety of formats (sizes) realize that larger formats offer a tradeoff: it's harder to create good images with a larger format camera, but when you do get a good image, you get a much better image than a smaller format camera would have acquired. IMHO, the same is true in digital. Maybe it's easier to shoot with a 50/2.0 lens on a 4/3 camera, but the 5D with a 100/2.0 (a larger more expensive lens) will produce better images when you put in the extra effort. David J.

I've been looking at some of the work some buds have been doing with their cameras. One has a Canon and uses the same lenses on his digicam that he used on his 35mm fim cam. Another has an Olympus setup with the dedicated 4/3rds digital-only lens setup. In visually comparing them side by side, it seems like the Olympus setup is more "precise" and consistent edge to edge vs the Canon. I'm wondering if others are seeing this too, and if so, is it because the Oly lenses are specifically tailored for their CCD while the Canon was not designed to optimize the lens to their CCD. I'd appreciate any helpful discussion or input. I'm not sure which way to commit when it comes to getting a DSLR, and I'd like to have as much good info and opinion as possible. Thanks When the sensor and lens are designed as a pair, you can get better results. Many of the other DSLRs are simply 35mm camera designs recycled with modifications using lenses which were not optimised for the job. Olympus (and the 4/3 system in general) were designed from scratch with the special needs of silicon sensors in mind. Having said that, image quality may not be the only factor in choosing an SLR - camera handling and the breadth of the system components may matter, not to mention cost. David |

Lenses have no impact on noise or colours. -- Alfred Molon Agree with noise, but lenses certainly have an effect on color. But I'd guess that Mark's point is to know what the problems were with the images to ascertain whether the camera, lens or operator were at the root of the problem. -- Skip Middleton www.shadowcatcherimagery.com www.pbase.com/skipm |

The finished digital image. If you are talking about cropped, finished images, I'd have to say, in this case, and without seeing examples, that the fault lies with the operator. Oly has a stellar reputation for glass, Canon's best lenses are among the best in the world. Since you don't say what lenses were being used, or even what cameras, only brands, it is impossible to answer your question with any accuracy. -- Skip Middleton www.shadowcatcherimagery.com www.pbase.com/skipm |

Many of the other DSLRs are simply 35mm camera designs recycled with modifications using lenses which were not optimised for the job. Olympus (and the 4/3 system in general) were designed from scratch with the special needs of silicon sensors in mind. Since we're talking generalities, I've read that the older 35mm lenses (in general) work very well on the smaller/newer sensors. Since you're "cropping" down the image circle, you're getting the sharpest part of the image. Most (all?) lenses are sharpest in the centre, and suffer various degrees/types of distortion at the edges. So (in general), lenses designed for 35mm film are going to be sharper than lenses designed for smaller sensor, and suffer from less distortion at the edge. I certainly see this when comparing my Nikon 18-70DX (an excellent "digital" lens) vs a nearly 20-year-old 50mm 1.8. Is this impression wrong? In what ways would a "digital" lens be "more suited" to a sensor than a lens designed for 35mm? Drew |
