sigma 150-500 knackered. result- well done sigma.
hi all. I posted a while ago that my sigma 150-500 hsm os wouldn't lock focus. well, I sent it off and they replaced an mr sensor, but they contacted me and said that the lens was still "very soft", and they wanted to send it off to japan for recalibration, all included in the repair price of £146....

And I forgot to say that when they checked the 150-500 HSM OS because I thought it was very slow to focus they could not find anything wrong, and then refused to charge me anything at all - even though I offered to pay the return postage. Amazing customer service! BTW: in case you did not know, t...

Mini and Classic Reviews
It would be interesting to see reviews of the older K and M lenses where the tests compare to those used for recent lenses. I might be able to help where I could bring some over when I stay over on your side and perhaps you could bring them back on a visit to this side. They'd all be K mount. See...

Irix 11mm Firefly
The problem is with a lot of these reviews is that they are some time in the past. There weren't any 36mp full frame cameras around in 2012 and the majority of cameras would have been approx 12-16 mp apart from the £5000 pro jobs. So excellent is in relation to those cameras . The Samyang is mushy w...

Irix 11mm Firefly
Going back to the issue of filters, the Lee Filters SW150 system is designed for ultra wide angle lenses and has a special mount for the Pentax 15-30mm. When I bought mine from SRB Photographic the boss told me that if one didn't fit they could make/adapt one that did - "it is what we do". 11mm migh...

DFA 24-70 - is it worth it?
Well I took the plunge and bought the FA 24-70 from Hullman, I confess I didn't take much persuading. So thanks Andy and great to finally meet. Just playing so far but it looks promising, focus is quick and sharp in poor light and it is for twilight and interior shots I really wanted it. I will give...

DFA 24-70 - is it worth it?
My question was is the FA 24-70 worth it. I am taken with how close it will focus, 38 cm, and here are some from my garden today. and the same cropped I think I am going to love this lens!

How are K1 owners finding their film-era lenses?
I have recently upgraded to a K-1 but at present do not have the funds to commit to any modern full-field lenses so have done a review of my lens collection to identify what I have in the way of full field lenses and have found 12 FF lenses over a range of focal lengths. I am more of a close-up/M...

How are K1 owners finding their film-era lenses?
[quote:3496ace15f="mattie"]I do, however have a bit of a treasure trove of FF lenses from my film camera days, and keen to know how people are finding such lenses - IQ, speed, anything of interest - when used on the K1. These film-era lenses are currently sat on a shelf as the focal lengths aren't ...

Cheap fish eye lens?
I paid exactly £100 on Ebay for the SMC Pentax-F Zoom Lens 17-28mm F3.5-4.5 Fish-Eye. It's FF, auto focus, small, and does the job - hours of fun guaranteed! For a review of this lens see . The problem is that only the first review is for the lens on Full Frame, all other reviews are with APS-...

Cheap fish eye lens?
I have an old Sigma 15mm f2.8 EX 180 degree full-field fish eye, AF lens acquired 2nd hand back in 2007 for around £100 which I have found to be a lot of fun on my recently purchased K-1. I was also surprised to find it recognised in LR5 which attempts to correct its natural distortion which I thin...

Cheap fish eye lens?
With fisheye lenses the usual relationship between focal length and field of view breaks down a bit. The improtant thing is to know whethr or not a lens is full frame (not in the format sense) or just a circle in the middle of the frame. Then, the field of view should be around 180 degrees. A few fi...

Lens Operating Ring Layout
While involved in a discussion to use a battery grip or not, I noticed the layout of the focus and zoom rings was reversed on the DFA 150-450 compared to other Pentax Zoom lenses. At first I thought it's to make it more comfortable to use the longer heavier lens, but then the the DA 18-135, hardly h...

Lens Operating Ring Layout
Hi Barrie Could be than the 50-135 is internal focus i.e. It doesn't get longer when focusing

Lens Operating Ring Layout
Hi Barrie Could be than the 50-135 is internal focus i.e. It doesn't get longer when focusing Don't know Neil. Looking at the photos for the DFA range and the new DA55-300 they are all focus ring closest and zoom on the end. Do we need a lens designer to explain why?

New Full Frame W-A Primes - when?
Pentax did a sterling job releasing five new excellent zoom lenses for the release of the K-1, even if two of these were developed by Tamron (and I'm OK with that). I know that a new 50mm F1.4 is in development and soon to be followed by a new fast 85mm, but I am surprised that nothing is in ev...

New Full Frame W-A Primes - when?
Strangely I've not seen anyone asking for what was the most popular telephoto prime for 35mm cameras :shock: Are photographers really that daft these days :mrgreen: -- Perhaps this is a reference to the 135mm prime that was so popular back in the day? I understand that this lens was popular becaus...

The 135mm on FF was an excellent portrait lens. See..... http://flickriver.com/search/nikon%20+135mm%20+%20portrait/interesting/ Pentax releasing one would also give the moaners a few other things to moan about such as they can't get shots in focus :shock: :mrgreen: I saw a checklist the ot...
