Dead Lens

Today I thought I'd try out my Canon EF 28 mm f1.8 USM lens on my new camera body. I took my EF 20 mm with me on holiday and thought I'd try out my 28 mm today. I took it of my old Elan IIe (50E) body and put it on the 60D body and went for a walk.

I got to the first picture I wanted to take, lined it up, the focus locked it in, but when I fired the shutter "Err 01" came back on the body! Strange I've never seen that before. Tried again and the same problem. I swapped the 20 mm back in and that was okay.

Back at home I tried the lens out on the new and old body and it worked some of the time but most of the time it didn't. On the newer body you get an error, other older body just goes stupid and needs to be power cycled.

A quick Google suggests that this another mechanically similar Canon lenses are prone to a problem where the aperture leaves stick. See the following on Flickr. I tried the non-invasive approach and it makes a lot of noise, the aperture ring either stays wide open or when it does stop-down it stays stopped-down. It's not a happy bunny...

Thinking back it now explains why the old camera would lock up occasionally. I had put that down to cold screwing with the batteries, but now it looks like it was just the lens sticking.

I can buy a replacement lens for £350 or try to get it fixed. I've just spent about an hour with Google trying to find contact details for a Canon approved service centres in the UK. Looks like I can expect to pay at least £100 for a repair...

Not in a good mood. Need a nice cup of tea to make me feel better I think.

Sundiver by David Brin

While on holiday this year I read David Brin's Sundiver novel. It's a very interesting book, but it's really showing it's age. Published in 1980 the book pre-dates the current era of ultra-cheap commodity computing and pervasive networking. The book's hero reads paper reports and there are multiple places where the actions set in 2246 seem strangely antique by todays standards.

If you ignore the anachronisms it's a good book, I'll have to get hold of the rest of the series from the library as most of them don't seem to be available on Amazon (last time I looked).

Summer Holiday 2011 (Day 11-13)

Yesterday was a travelling day. We left Brioude around lunch time and took the SNCF Ter back to Paris. It's mostly pretty country side and we had nice sunny weather so we had plenty to look at on the way. Once back in Paris we took the tube back to the flat and had dinner with family.

Today we went for a walk in Paris. We first took the tube out to Bois de Vincennes, a large forest/park on the edge of Paris. In one corner is a large flower garden - Parc Floral - which is free to get into mid-week. The had plenty of flowers on display, so I took lots of pictures - in particular in the Dahlia section. After the flowers we pottered about the forest, which is a good place to ride a bike or horse, then went back into the centre of Paris for shopping. A hot and slightly more walking than expected kind of day, but still very good.

Tomorrow we go back home on the EuroStar.
