Tamrons come uo all the time on eBay. I'm watching one at the moment.
I bought one last month for £62 inc. P&P and I like it 'cos its so much lighter and easier to handle than traditional lenses. There are downsides;
Fixed aperture at f8
Shallow depth of field
Bokeh produces strange donut shapes in some shots
Some people think they lack contrast

On the upside, they focus close at 1.7mtrs.

Tamron did a 350mm mirror lens as well and one of those is on eBay at the moment for spares or repair. Could be no good but I might take a punt if it goes for less than about £15.

49mm is too small and 52mm too big! I could try clingfilm????????

I have a very nice Cosinon 135mm manual focus lens which is I use for macro when used with extension tubes. It has 51mm thread size and I cannot get a protective filter anywhere in this size. I have also looked for a step up ring but no luck there either!
Does anyone know if this odd size is still available?
I would be interested to know if anyone else has come across a lens using this sized filter.

As long as the end result is pleasing to the viewer, does it matter how it was done?

I don't mean to be provocative, byt why do you get a fish-eye then get some software to "de-fish-eye" the results?

You do have your wheels on the pavement. That's enough for some of em' to have you locked up

Great stuff again,
I found a dead fly on a window sill, but it didn't look that good in the viewfinder.

Clearly a put up job. They all seem to be working at more or less the same time. Far more realistic if there was equipment everywhere and not a soul in sight!

2 & 6 for me. No cotton wool water on any of them which is refreshing to see.

Crackin' pics. Why did you sort of apologise for the wires in pic 1? You took a shot of what was there and the wires are part of that. To me, too many people want perfection, but the world is full of imperfections so we should accept them. I'm glad you didn't get run over trying to miss them out of your shot. A lot of the critique that comes out reminds me of HiFi equipment reviews that seem to ignore the music and listen to the sound system. Sure that's what they are being paid to do, but after a certain point they are splitting hairs. If the man who shot the Hindenburg burning set his camera up properly we would never have had the legendary images that we all know.
