Ruben and his Canon 500D
Photo taken by me.
FGC Renfe Rodalies between Clot and Besòs.
Ruben bought a new Canon EOS 500D (Digital Rebel T1i in the US) with a kit lens (18-55 mm IS) at the same time I bought the Olympus E-620 with a 12-60mm F2.8-4.0 lens (it's a hunk of glass!) On weekends we have been shooting similar subjects and testing various camera settings. One of the observations so far is that the exposure on the Canon may be ⅓ EV too bright and my Oly ⅓ EV underexposed. This, of course, can be easily adjusted, and I already have modified my camera.
We shoot for a while then use a memory card reader to look at the images on my TV. The images are big/detailed enough to notice differences. The idea is to "get to know" the cameras so that when we are serious, we know how to catch the shot. Sometimes you just can't say "can you wait a minute?" I know a lot of the "theory" behind photography, but it's a challenge to translate it to Spanish for Ruben when I want to explain something.
Ruben takes photos as RAW and JPEG at the same time. For a time I had forgotten to change my camera to produce RAW as well as JPEG, but now I do the same. Ruben’s RAW files run close to 20 MB each, but the Oly uses some lossless compression and are about 12 MB, about a 4 MB per file saving.
In contrast to the RAW file size, my Olympus JPEG files are larger, 8 MB, versus 6 MB for the Canon. That’s because the Oly has a “superfine” setting that has less JPEG compression than what the Canon offers. I use it all the time as it gives me more latitude if I choose to PP a JPEG image.
I think the build quality of my Olympus e-620 is better than Ruben's Canon 500D. (I ordered the cameras in the US where the prices are lower than on this side of the pond and had to make sure his camera worked before bringing it back. His Canon has a US- and Canada-only warranty whereas the Oly warranty is worldwide.) Interesting that Ruben used to have a Nikon F70. His choices were constrained by a budget limit, but at least I talked him out of buying a "bridge" camera and going with a DSLR.
