If the M42 lens has a pin it should line up with the plate that stops the lens down otherwise it won't work properly.

Hi Danny, I mean slow setting up and moving about
I'm not sure how long an 800mm telescope takes to move and focus
I used to see someone with a massive Nikon set up waiting for birds to come to him!!.... too much trouble to do it the other way around
I did post a link to a Pentax 600mm mounted on a tripod with an extra stay they had to adjust every time they changed the sight line It was made by Manfrotto.
Glad to hear it's fast being a screwdrive. I used to like the focus on the F* 300mm. SDM's haven't exactly set any speed records

Some mention of Pentax and the Tokina 80-400mm on Flickr.
Someone used it with a 1.4TC Flickr
And the usual Flickr pool
A post I did earlier with Pentax 55-300mm shots

Nice quality to the lens, both the softness and bokeh, especially
when it's not wide open.
Which lens and camera was it?

You should submit these to the Pentax Gallery

Pentax were rumored to have made 50mm's for other marques and the Ricoh 200mm f/4 is reported here as being the same as the Pentax-M even though the filter sizes are different.
Pentax urgently need an equivalent to the Canon 100-400mm lens
Or Tokina release their latest 80-400mm. I've got the older one which I think John also has (posted a shot once from Martin Mere) and it isn't too bad in good light, but I would like the latest version if Pentax aren't releasing one.
Just been reading about someone having problems with the Canon 100-400mm (which Canon fixed) on Wild About Britain and he had been using a 1.4TC with it but nowhere in 3 pages did anyone say there was anything wrong with that I wouldn't risk a TC on the Tokina
Frogfish... sorry haven't got time to argue and it isn't welcome on this forum. I would suggest you learn a bit more about photography in particular how most bird photographers use a lot of manual focus, so slow AF isn't a problem. 250-600mm zooms and adapted telescopes aren't fast to use either.
Two Pentax lenses you have put down the 80-320mm and 55-300mm are both excellent. The Pentax 1.7x actually does the focussing, so I can't see how it works for you with one lens OK and slow with another. Possibly you might be better moving to another marque, such as Nikon.

I don't know if anyone else noticed, but on the Canon test it stated:
"The 4 stop image stabiliser (vs the 2 stop of the 100-400) offers further advantages when hand-holding and shooting in lower light levels."
Quite a few Canon lenses only have a 2 stop image stabilizer and the people on here who have been criticizing the Pentax system should take note
He must have got the idea of fastening a note around an angle bracket for the test somehow off Don
This lens will cost about 10k but Frogfish reckons pros don't use converters and SHOCK! HORROR! it's a Zoom as well!!!

It should work as a remote OK. My RF-602's were marked as suitable for Canon and Pentax, so it may still work on flash. Test it it and see. Let us know what sync speed you get if it works.
Yongnuo seem to losing the plot a bit.

The thread seems to have drifted John. But what relevance does a test of Canon lenses and Tcs have to Pentax Users?
The OP said he was a noob and a Bigma was out of the question so he asked if he could use a TC with the 55-300mm..... simple enough I use a Pentax 1.4x-s with the same lens so as far as I'm concerned it's a working partnership I even posted a couple of photos, but others claimed you couldn't use a zoom with a TC and the Canon test clearly shows you can with actual pictures and not MTF tests. Pentax would have been better, but they don't make any, so no body will have any to test.
Photographers especially amateur are well used to using what's available so to say A + B won't work is a no-no. There's even been a link on this site to a Professional Fashion Photographer using a Mobile Phone on a shoot for publication. I don't remember anyone saying you can't do that.... you need at least a 645. It wasn't long ago that they were saying you can't use 35mm it needs to be 1/4 Plate
This is a good test with Canon Zooms and 1.4X and 2X TC's.
The Conclusion reached:
"The most significant conclusion that I can draw from these tests is that the 70-200mm f2.8 mkII can be freely used with converters and still totally hold its own against the bare 100-400 lens.I now feel that I don't need to own both a 70-200 and a 100-400 as the 70-200 mkII can do it all."
