The 1.4x and 1.5x converters I had worked fine with my 18-135mm.
That's reassuring to know thanks Mike.

I wouldn't know if the 200mm SDM will work or not with the
f/1.7 maybe johnwhit knows?

Yes it works with all SDM lenses, I have the Pz-AF 1.7x TELEPLUS SHQ. Pz-AF 1.5x TELEPLUS SHQ (KENKO) and the Tamron 1.4x. AFAIK Teleplus make all of them, maybe the Tamron uses different glass but it's a Teleplus design, the Jessops and others are just rebadged. Never tried a DC lens as I don't have one.

Hi Algi,
a couple of questions:-
1) Is there any way to get the menu to allow you to enter a corrected focal length when using a tele-convertor with a known lensas you can if using a non-Pentax lens in manual mode? (I have had to do this when using Canon FD lenses with an adaptor.)


Regards,
Kearton
No the option is greyed out in the menu, unless you're using a manual lens i.e. K, M, or A series. I've tried every suggestion to no avail.

Does the teleconverter send the correct EXIF data? If it does, is the focal length correct? ie does 150mm on the lens save as 255mm?
Unfortunately not, so SR is not optimal, but I've never put a lot of faith in SR when shooting wildlife, you need a fast shutter speed

Excellent TC, I've found that using the DA*300 tripod mounted the Teleplus 1.7x works fine AF wise, for some reason, hand held of resting on a hide shelf in my cupped hand, AF hunts. I presume it's the SDM trying to achieve critical focus but have no proof.

I have an old Vivitar 70 - 200 F3.8 Macro Focussing lens, the serial number start 42xxxxxx, that I bought in the 1970s to go on my ME. If it helps - the filter size is 58mm. I've struggled to find out anything about this lens on the various forums, and it's not even listed in a lot of the catalogues.

Can anyone enlighten me?
Are you sure it isn't the 75-205 f/3.8 as I've had one in the early days complete with matched multiplier.
