Standard lens advice
Thanks for all the replies. Looks like the 18-135 has jumped straight in at No1. Like the idea of WR, the DC focus, nice build and good range (i found the Sigma 18-125 was spot on). I'll just have to make sure my holding technique is perfect and find extra support where possible to combat shakey ima...

Standard lens advice
Hehe i think i'm more undecided now then before i started the thread :roll::D I think this is where i am now: Sigma 17-70 - Been reading the reviews of the new Contemporary Sigma 17-70 HSM and boy are they glowing. That's in the review section of the other US Pentax forum. Not sure i've seen a...

Pentax DA17-70 SDM - This really appeals too. Pentax glass and coatings. Only negative is the SDM. Should be a plus but after reading reviews and Googling, i stumbled upon so many disgruntled owners cursing SDM. But i think someone once told me Pentax fix it for approx £100 and fit an improved SDM t...

In a way you can see their thinking, the Pentax customer base is incredibly tiny compared to the other brands. Obviously don't feel they would get their development money back. Real shame. I've been waiting for Tamron to release their SP 70-300 VC with Pentax mount, the best consumer **-300mm on the...

Portrait Lens (50mm) advice
I don't have the Sigma, but I do have the DA50, and the FA50 F1.4. Wide open the DA50 is a lot sweeter and more contrasty than the FA50. Plus it is lighter and very cheap indeed. I have seen examples of shots taken wide open and it is indeed even better. But when stopped down the Pentax pair overtak...

Portrait Lens (50mm) advice
Thanks for your replies. There is another option if you don't mind slowing down a little and manual focus only. The SMC-M 50mm F1.7. Now that is a very good lens indeed and very cheap to buy. :D I actually have one of these on my Super ME but have never tried it on the K5. I'm doing a Gavin Hoey...

Portrait Lens (50mm) advice
I have had them both and would concur, Pentax was a gift, after much comparison of results sold the Sigma recently, as it became second choice, I guess that's the answer for me Regards I don't have the Sigma, but I do have the DA50, and the FA50 F1.4. Wide open the DA50 is a lot sweeter and ...

Did you ever come back Cider? I was just looking at some of my pictures with my M50 1.7 from last year and wondered how you got on with the lens?

Pentax A 1.4X-S Vs Kenko PZ-AF 1.5x SHQ
Hi folks, I know similar questions have been asked many, many times before and so I've tried as best I can to fully research my options before posting. Please bear with me! I own a K5 and the Sigma 70-200mm EX DG HSM II, and I want to get a teleconverter to complement the lens and gain a littl...

Which lenses for Astrophotography?
Good article, thanks for posting. For wide field work (aurora / milky way) I like my Sigma 15mm f2.8. Bit of a niche choice, but worked very well for aurora the other year, sharp right to edge of frame wide open. Apart from the aurora / milky way and general starfields, most other objects are sma...

Which lenses for Astrophotography?
Hi Gwyn - I have used the Samyang 16mm f2, but only on one partially clear night. I had a couple of issues: Firstly the fact that infinity focus is not at the infinity mark (a known "feature") makes it quite difficult to get accurate focus with my eyesight - LiveView seems to be less useful on th...

K3 and older manual lenses
As an aside, I can confirm the K-3 is brilliant with the older lenses, for several reasons: - It has focus peaking in 'live view', this revolutionises focus ease and accuracy with MF lenses - The 'focus confirmation' in the viewfinder is more accurate than with any other Pentax body I've use...

Has anyone got rid of a 55-300 and...
The 55-300 would make a very versatile travel lens with great IQ around its sweet spot. I don't regret getting rid of mine, I do regret not buying it back at a knock down price:evil: To be honest, prices what they are at the moment it doesn't seem worth selling anything.

Has anyone got rid of a 55-300 and...
I had the Bigma and 55-300. And as mentioned above, they are different lenses, the 55-300 can be taken along just for the sake of it while the Bigma cannot due to the weight and size. I don't know what you like to shoot, but I personally would rather sell the Bigma and keep the 55-300 as K3 allows c...

Every time I spend more money I think I'll get some back on the 55-300 as I can cover all those focal lengths. I never do though because it is such a bargain and so versatile. I'm glad I didn't. I took it abroad with me recently, got some great birding shots and remembered what it was like to travel...

Hi everyone, Wanted to know if there is a reputable shop that calibrates lenses for back focus issues (+10 on fine tune wont quite cut it). Thanks

Lens calibration shop
I've always wonder how lenses are calibrated. I've taken some apart to fix them and there doesn't appear to be any adjustments to alignment of lenses. It's all in software* - they just rewrite the look-up tables :) * if by 'calibration' the OP means having the liveview focus the same as the phase...

^yup. Whilst lenses do have plenty of adjustment for centration and position of the internal elements, this is to do with setting the length and centration of the intermediate images. It will however affect overall sharpness and bokeh (this is the variance we see within batches). It should no...
