Very smooth colors, and very sharp.. I particularly like pattern in the reflection on a compound eye.

Apropos tripod mounts from China for adaptall 23A etc...

I now have 4 of 'em. They are invariably described as being for Canon lenses in my case the 70-200mm f4/Canon EF 300mm F4L/Canon EF 400mm F5.6L lenses. In any event these are approx 66mm ID (and often stated as such). And at a fiver or a bit less each can't argue with the price.

As is they are just about spot on to fit around the 01F TC. Pic also shows one modded to fit 19AH 70-210mm, which like the 23A zooms in moving out. This is also same size for 300mm 54B.

I have been intending to mod one for my 23A so in a sudden enthusiasm here is how ....:

NEED:
1. LENS, MOUNT
2. CLING FILM
3. BODY FILLER PASTE eg isopon or similar (epoxy based pastes will probably work too but these styrene based ones are cheaper and easier to work with).

1. remove the felt from the mount. To peel it off in one piece and preserve the adhesive on it suficiently I have usually resorted to warming it over a radiator or stove.
2. I also roughen/clean the interior surface of the mount once the felt is removed with sandpaper.
3. size up the mount around the lens and estimate how much filler. Typically something between large marble and golf ball size amount.
4. IMPORTANT. don't forget to do this if you don't want the mount permanently attached to the lens. Wrap cling film - one layer is fine - smoothly around the lens where the mount is going to be used.
5. Mix the filler with catalyst/hardener and smear evenly around the interior of the mount.
6. ease the mount into position and close it so that that the filler is moulded to the contour of the lens barrel.
7. rather than letting the filler harden completely it is better to catch it while it is half hard or "green" - typically 10-30mins depending on how much/how old catalyst, ambient temp etc.. Then it is easy to ease the mount off the lens, jettison the cling film and use a modelling knife to trim off all the excess.
8. When the filler is fully hard, sand off any last excrescences and stick the felt back on. Voila!

PS you may note another useful adaptall trick in the pics: old canon fd caps work well - with a little trimming off the edge - as tamron mount end caps

I had some time upriver yesterday and took a couple of images with the Tamron 60-300.
This was taken at about 150mm or so.
Pentax K10-D

A very nice photo with a very good lens. I've been using 23As for about 27 years. Just a solid good lens with a very useful 5x zoom range.

Good news for US eBayers who might have a use for that tripod mount. There's a bunch of 'em there, ranging in price from about $6 to about $10. I did a search on "tripod mount canon 70-200mm f/4 EF" to find them. Without the quotes. Interestingly enough, my search picked up an orignail Canon mount that these are copies of. BIN price? A hundred bux.

Typical -- this particular one is being shipped from Orange County, CA -- but others are coming from China which means a wait time of as long as a month:

A real struggle last night to get enough light to shoot by, and no flash photography allowed - so ISO 1600 - where the Pentax K-10D maxes out.
Monopod assist - tripod was out of the question as the hall was packed for the concert.
Here ya go ..........

Oh man, chasing birds with a manual focus lens and poor light is not for the faint hearted.
I am disappointed with today's shoot. One of the better ones
ISO 800 1/90sec and wide open aperture

Excellent! You were shooting with the right shutter speed for motorsports, too.The wheels are blurred nicely.

Nice track action!

These are from my last outing with the 23A in Spring. 1/800-1/1600 sec. trying my best to keep up with them. Nearly all are at 300mm.

Those are some great airshow shots. I've taken my 23A to many airshows and auto races. Here are a few:

Not with 200mm?, you may be underestimating the size of these things perhaps? Or I am totally on the wrong track.

About any bug detects only rapid movements, so move very calmly and they literally cannot see you.

This is also useful for killing flies and mosquitos.
