Is the latest version of the Pentax 55-300 with ED glass and WR better than older versions
The latest version with the pulse motor is certainly a big improvement. A few from last fortnight in the Caribbean on my gallery here. Silent in operation, doesn't hunt, appears quicker to focus on my K3 and has electromagnetic stop down of aperture. I love it. F5.6 is at around 280mm which is an od...

Best portrait lens macro
The 50mm lens could be used for portraits, but probably not at 1:1 unless the portraits are of ants and flies etc. as 1:1 macro happens to be a very close focussing facility. The 35mm Limited is also a 1:1 macro lens. If you already have an 18-55mm zoom you can get some idea from that as to what t...

Best portrait lens macro
A true macro / portrait lens would be something like a Tamron 90mm, Sigma 105mm or Pentax 100mm 8) The Sigma has a focus lock so the focus throw can be limited like a normal lens for general shooting but can be unlocked for when you need macro magnifications.

Best portrait lens macro
A true macro / portrait lens would be something like a Tamron 90mm, Sigma 105mm or Pentax 100mm 8) Yes, on full frame, those were the typical lenses in the film days which is when they date from. Pentax's dedicated portrait lens was the 85mm soft focus. Crop sensors need perhaps a little less, 50-70...

Best portrait lens macro
The Da50 is a very good lens. Very sharp from f2.8, good colour, good contrast and as a true macro lens, it is sharp across the frame. It is also a full frame lens. Not all of these attributes are always wanted on a portrait lens. It will work for portraits, on APS C it covers the same field of ...

Best portrait lens macro
I posted this the other day, if they get them back in stock then this is the best price you'll get the DFA 50/2.8 macro for: http://www.johnlewis.com/pentax-smc-50mm-f-2-8-d-fa-macro-lens/p1091407 If you want a lens which does double-duty as a macro and general portrait lens then the 35 or 50m...

Best portrait lens macro
For portrait get the Pentax 50 or 70, or Sigma 50f1.4 and then a few cheap extension tubes to turn the lens into a macro. Best of both worlds. The macro lenses are a good alternative but you need larger aperture lenses for portraiture. Perfectly said :) Every now and then the ability to use a fa...

Mount Type - question
I've not got my mount illustrations to hand, so can't advice on the mount. It's not PKA as it has one of the linkages missing. CZJ lenses are pretty good but not upto the West German Zeiss standard. I suspect if you try a general photography forum rather than a Pentax specific one You'll have ...

The new 55-300 lens and the K50.
I took delivery of the new Pentax 55-300mm PLM lens late this afternoon. I hope to give it a good go in the morning among the gulls at the back of my home. Also I hope to post some decent shots in the forum.:)

Testing the M 50 f1.7
At 1.7 the eyes are in focus but the ears and the left and right edges of the object are outside the DOF. On the right hand edge you can make out that it is OOF and blurry and looks normal. On the left hand side you have the same OOF/blurry effect, but a blurred dark line is also apparent. Lo...

FA 35 F2 AL v D-FA 50 F2.8 Macro
Are you looking for its performance wide open, or any specific apertures? Thanks Lenny for responding. I will probably rarely go wider that f5.6 or so, or smaller than f13, so a range that most lenses excel. I'm switching back to primes for a bit, after an underwhelming experience with the D-FA 24-7...

Opinions on the DA 50
Recently I've been itching for a prime lens, the only one I own is the M50/f1.7. Great lens, a little soft wide open and manual focus with toddlers is a trial. I've had my eye on the DA50 which currently sells for £80-90 new, seems like a bargain. I do also own the Sigma 17-50/f2.8 which is...

Foot for a HD Pentax DAF 150-450 lens
No luck with B&H. They referred me Pentax which I tried again. I talked to a man this time that put me on hold and came back to tell me I will probably have to go through their repair dept. He told me he would do some more checking and get back to me if he found anything. It looks like JAK has g...

Pentax HD 1.4x TC
Has anyone tried the 1.4x teleconverter with DFA lenses on a K1? Googling compatibility with FF brings up lots of speculation but I cannot find anything definite. Logically it would only be used at the long end of telephoto zoom lenses like the 70-200mm and 150-450mm, as well as the 300mm lens so th...

Sigma 28-105 test
It's as fast as other screw motors, but yes some times fails to find the focus. I bought the new dfa for a decent price, I am going to try it as well
