Well Pentax seem to only have the 77mm LTD without
distortion according to PTLens link

You need to measure the diameter where the mount will go and
see if it's the same as any of the cheap Chinese Canon copies

It's easier to wrap a piece of 10mm wide paper around the lens
and mark the circumference, measue it and the work out the diam
from that

i.e. divide the circumference by 3.14159 to get the diam.

Panasonics have had in camera correction for years

You might be interested in this page belonging to another guy on the Wirral who has nestcams and free software, videos etc. Last time I looked he had used a TV Sender to transmit the nestbox cam to the house via a shed.

I used to use his Routerstats progam before I changed over to Virgin Broadband.

Interesting information... Thanks.

I presume the Channel Island Companies will charge the
correct VAT on items above the free limit?

What is the free limit? Is it about £17 and is that with or
without postage.

I recently bought a £16 memory card post free, which I'm sure
was below the limit via xxxxx, although it wouldn't matter
with this item (being below the limit) I was surprised that
the package had FREE GIFT written on it, considering that
they must send hundreds of similar FREE GIFTS out

Goldcrest and Treecreeper for me

Nice test It shows that there isn't a big difference
between these lenses. The non-SMC Takumar looks better than
I ever thought it would be. The 'A' lens is possibly on the
poor side of these lenses.

If I were to pick any I would go for the CZ because
it has much better bokeh and 3D look.

I can't see why people rave over the Sigma zoom based on
these pics anyway

What's the PC way to teach a child to say:

"Hast binman bin mam?"

"Dust min dustbin mon?"

If Pentax bring one out I would expect that it would be about the same price as the 1.7AF ones..... £300 - £350. Canikon TC's are mostly £350 - £450 so it would be unlikely that Pentax would be cheap.

Performance would probably be no better than current TC's on existing
lenses and bodies.

Jessops are usually rebadged Kenko's.

A Kenko Teleplus Pz-AF 1.7X SHQ TC sold on this forum last September
for £175. link I think the 1.7x Promaster is the same.

I remember seeing somewhere that the 1.7x's are nearer to
1.5x..... although there's no standard for TC magnification
specs.
