• Its a way of using some of the greatest lenses ever made (ie. there a massive variety of lenses to try),
• They’re generally smaller, lighter, and cheaper than modern lenses,
• Many have unique characteristics and draw nicer than modern lenses,
• Build quality that still shits over most modern lenses,
• Trying something different for the hell of it.

As you can see, theres several good reasons to consider using older lenses.
From using film cameras recently, i’d already built up quite a selection of Zuiko lenses for my Olympus OM bodies. Luckily, Zuiko have made some of the best lenses in history ( you cant dispute that its a fact), so i got a cheap adapter off ebay to start using them on my DSLR.

I’m not going to keep rambling on, so i’ll cut to the chase.
This afternoon i attached my newest Zuiko, a humble and underrated 100mm f/2.8 that cost me $55 including postage from the U.S. The light was going down, and the wind was pretty strong, but f/2.8 is still pretty respectable even if it’s not exactly “fast”.
Here is what i came up with shooting wide open at f/2.8 at 200ISO. There is no processing whatsoever, its straight from the RAW. No sharpening, no level/colour adjustments. I’ve also included a 100% crop of the image. **click images for full size, the resized ones can look a little soft**

100% crop

Shooting with a manual focus lens on the 400D isnt the best combination you can think of. The viewfinder is pretty small, and it doesnt have a focus screen designed for manual focus lenses. You can buy them and they’re relatively cheap, but i probably wont bother unless i upgrade to full frame. I’ll definitely be using my other manual focus lenses form now on though and im looking forward to using the 100mm for some portrait work.
