Pentax European Warranty - Length
It is inconsistent, often not finding anything in the frame to focus on, in continuous and now and again in AFS mode. After initial focus lock in c mode it will not change focus unless (back button focus)it is released and repressed. It makes a strange rumbling noise. This cannot be normal. It was b...

Pentax European Warranty - Length
Send it back to JPS, if they find nothing wrong then they won't charge you, if however they do, they will repair it properly and set it up to as new standards, they are not cheap or quick, but I'm happy with the repairs they made to the lenses I've sent back to repair in the past. Andy

Pentax European Warranty - Length
Finally got lens back and it is working well now thankfully. Went to JPS via SRS who said they couldn't get the parts for the SDM repair which included matching circuit board. Went back to SRS then Johnsons so took 2 months and £200 so I hope it continues to work well for at least another 2 years!

Pentax A 50mm MACRO on Ebay now
I agree with you oh Monk of Darkness :) btw £99 for that lens is ridiculous. I wouldn't pay more than £40 for one. I have all the other A 50s Ha! Ha! That't Funnee! :mrgreen: :wink: One of the best lenses ever made and it's not worth £99 :shock: If Zeiss made it it would have a £3,000 price t...

Searching for portrait lens on a budget
The lenses you already own will cover it very well, but if you fancy a prime portrait lens then the current classic lens would be the DA* 55mm f/1.4, which gives the same view that the classic portrait lens would on film. That would be the 85mm f/1.4. Other great lenses for the purpose are the 70...

Searching for portrait lens on a budget
Thanks everyone for the kind feedback. Very useful. So apart from The 135mm everyone seems to be stuck on the 55 da. I will look into the m 55mm and get back to you. I suppose the question is, if I have a 55-300 is that lens decent enough for portraits or not?

The 55-300mm is a great lens, but the maximum aperture is quite restricted. This makes out of focus backgrounds much more difficult.

True John, but an out of focus background isn't the only priority for me when I look at a lens. The 55-300mm is a great lens, but the maximum aperture is quite restricted. This makes out of focus backgrounds much more difficult.

lens reversing ring
Hi all. im after a 49mm ring to use on a A28mm lens (has aperture ring) I bought a 49mm lens reversing ring off ebay for about £3.00, but i have been sent a 52mm ring. It doesnt seem very good quality, and it is really difficult to get it on one of my 52mm thread lens. I was wondering if anyo...

New 16-85mm wr
£600, I just feel it's the replacement to the slightly troublesome 17-70 F4, wider longer but variable aperture, the big two both do them, not really that expensive as it will drop to the same level as the Nikon 16-85mm soonish. Theirs is currently elling for a whopping £573.79 at the Nikon UK store...

Poor Man's 50-135mm?
I can vouch for the A35-105. I was very lucky, I was given this lens, along with a couple of others, by the original owner.It was lucky coincidence - I'd just bought my first DSLR - my first Pentax - and he'd had his old Super A and lenses sat in a bag for 20 years so gave them to me. It's tak...

Square Bokeh from a Helios 44-2
The last image does have something, but I'd ask why we need the left side of the picture? I would crop at a point that eliminates that out of focus half and the vertical white slash, then we get a powerful graphic image left.

Pentax Forums reviews the Sigma Art 18-35mm
Don't know really, Andy? I read somewhere that Pentax use F2 sensors but just rate them as better than 2.8, no idea where though! What strikes me about the review is not really how good the Sigma is, as it's fantastic in all areas except the focus thing, it is a very very bright zoom lens, so it ma...

I have a Pentax A50 f/1.2 and it's worked great at 1.2 with all the Pentax DSLRs I've owned... K10D, K20D, K-5 ( three of them ) and K-5IIs Did it auto focus? Jeff

Pentax Forums reviews the Sigma Art 18-35mm
Wonder if there is a difference in focus accuracy between the K5 and the K3, the focus points on the K5 series are some eight times bigger than on say, a Nikon D7100. it may well affect accuracy somewhat? K3 would be a bit nearer the D7100 in that regard, the sheer angle of the light hitting the sen...

Difference between m and a
Looking into purchasing a smc 50mm in the next few days for portraiture but can't seem to find the difference between smc 50 M and smc 50 A. I know it's not auto focus. What is the difference
