FS: Jessops MC 1.7x Pz/AF TC (identical to the Pz-AF 1.7x Teleplus SHQ TC)

Excellent condition. Looks unused.
Has all the contacts for HSM/SDM 7 contacts each side + Pz contacts each side.
Original top and bottom caps.
No box or case.

£149 inc. RMSD to the UK. Sorry no offers I'm already losing on what I paid for it.

Works well with Sigma DG 150-500mm F5.6 - 6.3 APO HSM latest Optical Stabilizer version
and makes it a very long but usable lens.
The Sigma Optical Stabilizer really does a good job.

It also works well with Pentax 55-300mm screw drive which is what I bought it for, but
didn't realize that it was identical to the Pz-AF 1.7x Teleplus SHQ TC which I already
had. I wanted a lightweight outfit to carry around that would go beyond 500mm and this fills the bill.

It works with my only SDM lens Pentax DA*300mm f/4, but you have to keep pressing the AF
button to get an accurate focus. I wouldn't therefore recommend it for an SDM lens the
Tamron 1.4x would be better, but that isn't very good with the 55-300mm.

Loses 1 to 1.33 stops which can easily be covered by
increasing the ISO

Only the Jessop TC is included in the sale, but I have also shown the Teleplus
in the following photos, so that you can see that only the labels are different.










Because I only want to keep one of these TC's I will sell the Teleplus if
anyone prefers it, but it would have to be £30 extra to cover what I paid
for it.

I like all these, but my favourite has to be the cat

This screen grabs 1000pixels wide so here's a direct link to it.
Very slight difference in size which doesn't really matter.
Both shots were the best of 4. The Sigma will probably be better
at f/8 it is a very good lens.

The Pentax 55-300mm + Jessop 1.7x TC also gives a
narrower field of view than the Sigma set at 500mm.

I might as well add a couple of hand held sots taken with the Sigma
150-500mm plus the Jessop MC 1.7x Pz/AF TC last week.

The 55-300mm + TC came out slightly sharper than the
Sigma 150-500mm without TC at 450mm and f/7.1 on the
Sigma.

Obviously it will only work with a TC that suits it and like all
long lenses you need to have good focusing technique. With the
55-300mm it's better set between 10M and INF before you start
and the target is better if it's got good contrast.

The Jessop MC 1.7x Pz/AF TC hardly effects the performance of this
lens and I'll be leaving it on my lens more or less permanently
from now on. It loses 1 to 1.3 stops which can be allowed for by
increasing the ISO.

I've also got the Sigma 150-500m, but it's far too heavy to lug any
distance and the DA*300mm is too restricted to the one view.

Just looking through some shots taken recently with the
Pentax-DA smc 55-300mm f/4-5.8 ED + Jessop MC 1.7x Pz/AF TC for another thread.

I've also been using the TC with the Sigma 150-500mm without any problems.
It works with the SDM on the DA*300mm f/4 but you
keep having to press the AF button to get exact focus.

It's identical to the Pz-AF 1.7x Teleplus SHQ TC which I also have so because
I don't need two with the same spec/performance I'll be putting it
up for sale in Classifieds shortly.

For nature photos the Pentax 55-300mm + suitable TC is very light
and gives good IQ and closer focusing.

My copy of the MkII is very good and the Mk 1 I had gave
exactly the same performance. The colour is also excellent.
