Standard zoom options for the K1
What you want is the Pentax new D-FA* Platinum Series 10mm-150mm f2.0 (a prototype I've been testing for them for a year or so now), it has a 49mm non rotating filter ring, weighs 232gm and is 84mm in length and targeted at a RRP of £249. I find it covers most needs - but until it's released you'll ...

Comparing Close-Up Lens Choices
McGregNi, I use a Marumi 5+ achromatic macro “filter” on the DFA 28-105mm for excellent results close up. It is handy to keep in the bag and just pop on when opportunities present themselves without the weight and expense of a separate macro lens.

Graduated Filters on the Pentax DFA 15-30
I am with Pete, the Lee Filters SW 150 system. Also use adapter for the system on other lenses. As the glass on these is through-coloured and the light has greater thickness to pass through you will notice vignetting at very wide angles with six stop and ten stop filters, and also the glass imparts ...

Graduated Filters on the Pentax DFA 15-30
Thanks for the advice on Lee guys.. But I have already invested in Kase filters and stoppers. A glass filter system that has no vignetting or colour residue. I consider them far superior to the Lee system.. They have their own holder systems to fit our lenses, and as Im certainly not a full time lan...

Graduated Filters on the Pentax DFA 15-30
I had a similar dilemma . I wanted a modern wide angle for the K1 which could use graduated filters. The Pentax 15-30 would be fine except for the filter issue. I thought that having to invest in a Lee / Nisi/Kase system for 150mm filters for just one lens was really having the 'tail wagging the d...

New DFA 50mm f1.4
The truth of it is that either lens will still probably out-perform my capabilities :wink: That certainly applies to me and it's one of the main reasons that I'm not interested in the K-1 or its monster lenses, along with the reality that, as I get older, I don't want to carry around such size and...

On no, I've been converted!
So I used to be an almost exclusively zoom lens user. For a long time I have had the DA*16-50 and DA*50-135 as my two go everywhere lenses. I also have a DA18-135 but it is on 'long-term' (permanent :lol:) loan to my father. For a long time I'd been umming and arring about the Limited primes. Every ...

Blackstone or Firefly for the Irix 15mm
After months of soul searching for a super wide angle lens for my K1. Still cant bring myself to pay the Pentax 15-30 price. Though I don't doubt its capability, as a lens. Its also auto focus with a more sensible filter ring size. But the reviews of the Irix 15mm manual lens are receiving mor...

Blackstone or Firefly for the Irix 15mm
Interesting. Thanks for your input Haris.. One of my main concerns is actually over both. And the 95mm filter thread and if I will require more new filters. I have 100mm filters and bracket but worry the bracket will be seen through the lens...? I believe the Irix gel filters are relatively poor acc...

Blackstone or Firefly for the Irix 15mm
Oh yes, I forgot to mention the dealbreaker for me... the 95mm filter size means your 100mm system will introduce vignetting. I'm happy to not use 100mm filters on the lenses and am also keeping an eye on a few 'thin' filter holders, mainly from China. And since I have a FA 20-35 at the moment...

Tamron SP 90 macro or Pentax 100 WR macro
I find the Pentax 100mm macro gives excellent results and as Jak says works well with the Pentax AF160 ring flash. It zooms in and out to focus and the front element with the filter thread doesn’t rotate. I only wish it had a silent motor built in as it can be a bit slow and noisy to focus, and the...

IR focus register marks
Thanks, Gavin & Mike. In live view, with the R72 filter on, it's too dark to focus, surely? Isn't it? Roger.

IR focus register marks
Back when I had a converted K01 I used the ir points on my m 28mm, f8 and focus points lined up and was good to go no issues at all. Same when using the r72nm filter.

Pentax D-FA*50/1.4 introduced by Ricoh (UK) and SRS
i always thought the more elements the less light which makes it slower Whilst coatings have improved over the years, it is true that that there will be some light loss and any air/glass surface due to reflection rather than transmission. So to maintain a given speed or light transmission, the more ...
