Teleconverter for 300mm lens`
The 1.7 was designed to provide AF for Manual Focus lenses. It focuses within its self, it does not alter the focus of the lens. The 1.4 transfers focus through to the lens it's self Thanks Barrie

Teleconverter for 300mm lens`
Quick update the 1.4x AW arrived yesterday, I used amazon as I had a few vouchers to put towards it and it was a good price - maybe too good, as noddy inspection suggests it's an open-box despite being sold as new. The teleconverter is immaculate and looks new, just things like the paperwork was ba...

If it's Amazon then take pics and speak to customer service. You'll be able to get a bit of money back that way.

Pentax DA 50mm F1.8
I tried on my 55-300 and the Picture came back way underexposed, it's ok with my 50mm but the 18-50 and the 55-300 just no good indoors, i have a Meike MK910 for my Nikon which works pretty good considering it been sat in a drawer for almost 5 years. I wanted something similar to that with a Screen ...

MPB site-
Hi, I'm looking at getting a reliable 17 or 18/50 f2.8 lens and saw Firstly, I presume the site is 100% trust-worthy & legit. Why is the Sigma 18-50mm f/2.8 EX DC Macro - Pentax Fit so inexpensive on MPB? From reviews, it's a very good lens..... constant f2.8, autofocus, sharp. Is there som...

Kenko 2X MC-7 teleconverter with Pentax cameras.
I have a Kenko MC-7 teleconverter, It doesn't autofocus with DA* lenses, but it does autofocus with my Sigma 105 f:2.8 macro lens and my Pentax 12-24 f:4 wide angle zoom. It also works with my D-FA 150-450 lens, although it doesn't always "nail" focus on the first try, probably due to the rather s...

Kenko 2X MC-7 teleconverter with Pentax cameras.
The Kenko MC-& has the contacts for SDM. It would not focus the 150-450 without those.

Extension Tubes With Laowa Lens - Question
Am I correct in assuming that the back of the Laowa is fouling the stop down couple lever? I have just been fiddling with my Jessops extension tubes and have come to the conclusion that the only way to achieve what you want is to remove the lever - not to be recommended, though. The alternative woul...

Extension Tubes With Laowa Lens - Question
Yes, the Laowa doesn't have a slot for the lever to go into. I did wonder about removing the lever but decided against since it's only for an experiment and Murphy's Law says that when I want to put it back I won't be able to find it or, even worse, damage the tubes while removing it. TBH, I was ...

Extension Tubes With Laowa Lens - Question
An interesting suggestion, but you presumably haven't had the pleasure of a close encounter with the lens...:wink: It is very specialised, only for ultra-macro. Depth of field is always much smaller than 1mm and the range of focus is very limited - approx 4-5cm from front of lens, not capable of foc...

Weird lens issue.
Out of curiosity a while back I purchased from the bay a 24mm Miranda PK A lens. Cheap because it had a smidge of fungus, but I cleaned it up and it seemed OK. I decided I liked the format and found another cheapie, a Sigma PK A 24mm lens. On arrival, the lens looked in very good order but wouldn't ...

Pentax K200 f4
I do enjoy using my old? lens, taking control back from auto everything, although I still use modern lenses on moving subjects.

Newly Discontinued Pentax Lenses...
Sluggish focusing is a bugbear with the 100mm macro, although I recognise that manual focus gets used a lot. I had a recent shoot with the ring flash attached because the light was poor and it just couldn’t find focus, so I had to work manually. As it was an event I was documenting I was a bit rushe...

I always focus manually with the 100mm macro and then switch to auto focus when I know I have got the focus right. Of course, I was brought up" on manual focus lenses so old habits do die hard - to an extent

There is a new version of the 100/2.8 coming. Apparently the old one has horrible purple fringing, though I don't remember anyone ever mentioning it. I too thought the 14/2.8 was discontinued years ago since it always played second fiddle to the 15/4 and never got great reviews. Hopefully the...
