SMC-M 100mm f2.8
I did mean to mention that the lens you have is not a macro lens but a normal telephoto. If you really want to get very close for small insects and other small subjects then a proper macro lens will be marked as such. "Macro " zooms do not substitute for a proper macro lens as they do n...

SMC-M 100mm f2.8
Welcome to the forum Clarky. It is great to see another Aussie here, we are few and far between (at the other end of the Universe so I have heard). Macro photography is a lot of fun and is nearly impossible to run out of subject matter. The K100D is a perfect camera for the job, but ultimately th...

Hiya, "(save for the macros, where the exra speed is not a huge benefit, given that they'll mainly be used at f11 and smaller)" George..one point...that is the traditional way macro shots are taken, with loads of DOF and everything in focus. There are an increasing number of creative...

Brand New Carl Zeiss lenses now in Pentax KA fit!...Zeiss ZK
As George said, it's a great compliment to Pentax. I'd like one thing to come out of this event: Pentax offering split-screen focusing screens for the K10D (and maybe for the K100D Super too). They are manual focus after all. This would make using the manual focus Pentax lenses much simpler.

Besides what you'll find in the description on the Pentax websites, hopefully superior quality to the non "*" lenses produced by Pentax. Anyway, - Water/dust resistant seals. - Hypersonic motor for silent auto focusing (on K10Dand K100 super). Normal focus for everyone else. - Quick...

Insane..........I only got £165 for one a few months back :)

Can anyone enlighten me how this little device works? Is there a moving device within the TC that changes the plane of focus? I can't see how the TC changes the manual focus lens because there are no mechanical linkages to move the focusing ring.....

If we are talking about the same thing (excuse my ignorance) but 2 sold this week on E-Bay Aust for about $150 or about 60pound one was a 2X KAX Pentax Macro Teleplus AF MC7 Japan Auto Focus PK and the other was a MC4 not sure what the difference is ???

Wow....I got a mint one years back for $20.00 canadian. Mine gets used regularly with my 50 1.4 and my 85 soft 2.2. Stunning images when used with the 2.2...I'm bad at math, but 85mm, times 1.7 af converter,times the 1.5 crop on digital equalls lot's of happy female portrait subjects!

DA* 16-50 Someone has one!
Out of curiosity, is there anything at all about one of these lenses that you could post on the web*, that would convincingly show the benefit of having a 16-50 DA* as opposed to a 16-45, as opposed to a peasant's kit 18-55? What's the actual difference between these lenses, in reality? How good...

DA* 16-50 Someone has one!
I shoot Weddings..... faster focus, less noise, ability to get images in lower light, with faster shutters and less flash ARE exactly why I'd want those lenses. You have to use what works. There's always trade offs. You can get excellent images with all three lenses. The question is HOW MANY exc...

DA* 16-50 Someone has one!
I really don't find my 18-55 is fast enough and the corner sharpness is not good. F2.8 would be very good in dark situations/indoors and for shallow DoF. Well, you ask what is special about it, it is a constant F2.8 zoom, that is the main reason for getting it. If you don't need a fast len...

DA* 16-50 Someone has one!
I find the f5.6 at the wide end of many lenses very limiting, especially in lower light, so this is why I have been buying many of the 'faster'lenses... f2. 8 is great for portraiture etc where a shallower depth of field is desirable..... If it gives sharp images, with minimal CA and no vigne...
