SMC Pentax 135-600mm 1:6.7 Zoom
Dan, I have tried the 'ole faithful' shot o' the full moon using this monster on my *istD with mixed results. The biggest problem, apart from its weight and bulk, is keeping the thing still on the tripod. I use a Manfrotto 055PROB + 488RC2 ball head. The first modification was to remove the ru...

Lens range expanding??
There is a lens roadmap in PDF format on their main website. Current lenses listed here Of course you can use all their existing lenses back to and including M42, and the Samsung lenses should work. However there is plenty of coice in the Pentax line alone, thought Sigma and others do mak...

Lens range expanding??
Also, the Pentax 10-17mm fisheye zoom is unique, and is the envy of many other system users, to the extent that I saw one Canon user say they'd buy the K100D just so they could use this lens. its amazing how many canon users are ignorant of what I consider to be the only major benefit of their s...

Lens range expanding??
I'd buy one. Peter, I do hope you haven't got a Canon upon which you wish to fit your Pentax lenses. :shock: Or did you mean to get an aperture (apparature) ring on DA lenses to use on your Pentax's? What is the plural of Pentax? Pentaxes? Pentax's? :? Dan it wouldn't work on a pentax, the...

Lens range expanding??
Why doesn't someone make an adapter with an aperture ring? Whose side are you on? :lol: We need to make them buy Pentax, to see the error of their ways! :twisted: But anyway, I suppose you could make an adaptor that would move the 'aperture activation lever'* to the required position to close t...

PFA 100mm F3.5 Macro
This lens is quite a simple one of 5 elements/4 group construction. Both the DA and FA versions are 9/8. It is a "budget" lens along the lines of the Takumar A series lenses and will only focus to half life size. If you only need a macro for the odd use or for webwork, it is probable worth...

Apertures, what is it worth paying for?
I was having a discussion about maximum appertures with a Cannonite (friend) a couple of weeks back. He has a F1.2 L series on pre-order, which will be some astronomical price. We got to talking about the maximum apertures we had come across, but I fail to see why small increases in aperture are ...

Apertures, what is it worth paying for?
Agree with Kim ;) It's not just about maximum aperture. I find the Pentax 50mm/f1.4 absolutely sublime. As Kim mentioned, the 1.7 is extremely sharp and flat-fielded (is that a word? :P). But, the 1.4 with 8 aperture blades (as opposed to 6 of the 1.7) produces such a beautiful soft out of focus re...

Merry Christmas
Heres something to cheer everyone up after the stress of preparing for the holidays Just finished reading a lens test in the new "Digital SLR" magazine the Pentax and Samsung 50-200 scored quite well, the test said the Pentax was one of the best in the bunch for build quality, the ma...

Macro Options for K10d
Try eBay, but buy carefully, or alternayively try the ads at the back of AP.

Macro Options for K10d
That's a fair point. Personally I don't think AF is all that important for macro work, so maybe a manual focus macro lens will suit you. It depends upon the sort of macro shots you plan on taking.

Macro Options for K10d
That's fine, and for portraiture AF can be very useful. The sort of macro work I do does not really benefit from AF, so I turn it off and focus manually, but for other types of work the AF stays on. It's more a matter of what is suitable for the purpose, what is ideal, what can be worked around if b...

Macro Options for K10d
I have the SMC-F 100mm/f2.8 that I picked up for £200 from LCE a few years back. On the K10D the quality is absolutely astonishing! (My "chair" : http://www.ephotozine.com/gallery/showlargepic.cfm?photoid=785575 should hint at some of the detail possible! At full resolution it is soooo ...

Macro Options for K10d
they list 7" but I _swear_ it focuses down to 2" or so manually Quoted focus distances are often measured from the film/sensor plane rather than the front element.

Not sure where abouts you are javam A fair point, I have updated my profile to include location. Thanks for the pointer about SRS, but I was told elsewhere that the pentax mount had not been released yet. There is always a chance that they are delayed due to development of a version that expl...

A fair point, I have updated my profile to include location. Down there at the end of last January, when we had all those overcast, gloomy days... :D ...Back on thread - I've no idea whether they have stock, or whether they've just got the lens listed for when they do, but it's worth a r...

SMC M 50mm 1:2 K Mount Lens
Hi Mac, I've just looked through the ones I took with the f2, and it being a Halloween party all the good ones contain kids. As I don't have permission to post them here, I'll be back in 20 minutes.. I'll go and take some outside, now that it's dark.. :wink: Cheers Liam

SMC M 50mm 1:2 K Mount Lens
I'm back.. my eyes are done.. I've been manually focussing an f2 lens and failed on almost every shot (hence the reason I bought an AF 50mm) 8) , but I'll just resize a couple and post them up in a mo. They won't win any competitions, but they are meant to test the lens, not my eyes.. :oops:

It wasn't worth the effort.. :wink: I can barely see the screen now.. :? It was raining, so I did these inside, without flash, and with no sharpening.. no really. :cry: First one was f22, second f2.. and I already know I haven't done the lens or my own capabilities any justice whatsoeve...

SMC M 50mm 1:2 K Mount Lens
just wanted to chime in in support of the lowly F2 50mm, I take my 50 F2 on a Ricoh KR5 where angels fear to tread. It has always come back so far and I've had people call me a lier when I tell them it's a £10 lens on a £30 camera which took "That" shot. Stop that baby down to F8 or so ...
