Pretty flower picture of the day
The el-cheapo m42 to k-mount adaptor I’ve got to fit my two screwmount lenses onto my *istDS is just a teeny bit out of spec; the (huge) Tamron 28mm lens claims to have an 22cm-∞ focus, but this adaptor is enough of an extension tube so that 22cm is about 5cm and ∞ is about, um, 5 meters.
It’s not a particularly good long-range solution, but it will give me a chance to play some macro games until I get out the saws and files and trim down the adaptor so that I can focus on large mechanical devices at a reasonable distance.
