What lenses for the new FF
The lens map shows a full frame 16-28mm fast zoom, that will be expensive though. As for older lenses particularly the old k and m lenses I feel the newer sensor will out resolve those lenses. Hi Gary, I'm sure the new sensor will probably out resolve some FA lenses - this isn't my concern - I'd be ...

The 'K' 30mm f/2.8
Quite some time ago I discovered that Pentax made this odd lens. Only odd in the sense of "who makes a 30mm lens?" Well, Pentax of course (one thinks of 31/43/77...). I then discovered how expensive they are! Then about a year and half ago I managed to pick one up from a forum member for a sane p...

The 'K' 30mm f/2.8
Your second paragraph is back-to-front Nigel. Centre weighted metering will see the brightness of sky, think the light is brighter than it is and hence under-expose a scene. However, using centre-weighted with intelligent use of exposure compensation will allow correct exposure pretty much 100% o...

DC watch Pentax 16-85mm lens review...
It just does not have the quality feel of say the 16-50 or the Sigma 18-35 or newest version 70-200. I personally do not like the styling which looks a bit toy town to me but that is just my opinion. More importantly, the results seem good so far. I'm quite impressed with my da16-85. Having seen the...

100 Macro Vs HD 70mm Limited...
Thanks Brian, I didn't know you had left the fold, still using for film then I take it? Addendum: Oh I see, you went X-T1, had one of them too! I've been too-ing and fro-ing for a long time, I'm now wanting to do everything with my K3, which means a few changes and some designs on bigger and long...

100 Macro Vs HD 70mm Limited...
Definitely a difficult choice there. The DA70mm is a lovely lens for landscape. Small, sharp, fast focus, contrast and build quality are great, but you knew that already. Things that you will find useful are the small light compact package. I find the retracting hood really helpful. Close focus i...

100 Macro Vs HD 70mm Limited...
I no longer own the DA70 (that's no reflection on its qualities - it is a Top lens) but it really does sound as though it is the better of the 2 options for you. I take my DFA100WR out with me quite often but almost never use it for non-macro stuff, the longer focus throw is distracting and it's a b...

100 Macro Vs HD 70mm Limited...
I've gone 15, 35 macro and 77 for my walk-around kit. The 77 is just sublime. Every time I stumble on a picture that just jumps out of the screen, I discover it was taken with the 77. There are still plenty of duff or unimpressive shots; it can't work miracles, but when it works, oh boy :) However,...

Pentax 1.4 rear converter comparison

Compare WR to non WR lenses

Problem with extension tubes
Hi Kris, If as sterretje suggests it is due to the black paint than you might want to remove a section close to the contacts area. This is what I had to do with my Petri 28/2.0. The aluminium foil trick does work, but if it bunched up or rips you run the risk of little bits of foil inside your ca...

15mm f4 - soft copy?
hello, i got the 15mm limited last month, and i've just come back from a wkd in barcelona where i tried it a little. I had high expectations as it's my first limited lens. Of course i have read every review on the pentax forum (9.26 score), and i am aware it needs to be stopped down to f8 or even f...

15mm f4 - soft copy?
here are two shots,. it's not bad in the center - the ones that are bad everywhere are the ones taking trees from far away, i.e assuming it didnt focus right. this is all acceptable of course, but nothing amazing

Pentax vivitar extension tube query
For macro, just don't get hung up on auto focus - it's next to useless. The best MO is to get an approximate manual focus and then rock your entire body forwards and back to find the most effective focus point. An A series 50mm on the end of tubes is an ideal combination, as David has shown, above. ...

Pentax 150-450mm
It's done. I took delivery about 20 minutes ago, having ordered the lens from SRS yesterday afternoon. Initial reaction is excellent construction, fantastic lens hood, brilliant case to carry it in. The case is pretty much essential as this lens is big and heavy. Focus on the K-5 is fast and tota...
