Thanks Nulla,
Does your copy CA at 16mm. f2.8.
I suspect it being soft at corners at 16mm f2.8 is normal... i hope..
no decentering issues.. though.

Cheers
Shang

I sent my first copy back becasue of bad CA. My second copy is out for delivery and I expect to have it tonight. I'm hoping I get a better copy this time.

I can't see any edge softness in the jpgs above, and it looks OK left to right. The CA would not be visible in thes JPGs either since the compression would overwhelm a subtle effect like CA. For example, see the building edges in your first shot - there is a bunch of JPG noise at the sky-building intersection that would make a little yellow fringe seem trivial.

Have you tried correcting the CA in lightroom or photoshop? It's usually easy to correct. In my case though the CA was so bad it affected images even at 28mm and above, and fixing the problem on every image was just to much work for me.

I have only had minor issues with CA.. and both times high contrast situations and I would not have picked it up but for enlarging.



Shang I hope you enjoy this lens even half as much as I enjoy it.

I am off to Cairns and Port Douglas later in the month and looking forward to getting the most from this lens

DA* 16-50 on a K200D - Examples Anyone?

As the title implies. I was wondering if there's anyone out there with the combination of DA* glass and a K200D. I'd like to see what exactly is possible with this lens. I've seen the 50-135 demonstrated with a K20D in another thread, but was curious if the K200D can really make the most of the lens. I noticed a lot of people on here have K10 or K20s.

Also, because is a hell of a lot cheaper, K200D shots with the 50/F1.4 prime lens would be lovely too. $200 vs $900 is a lot of cash.

Thanks guys!

I'll jump in and simply tell you to buy the 50/1.4, and don't think twice about it! It's not LBA if it's practically required to be in your bag... at least, that's what I tell myself! Seriously though, I can't describe how much I like that lens. Now that I have it, I'll never let it go. unless it's to fund the Bigma purchase, of course.

The k200d should respond similar to the k10d as it has the same sensor. Some of my test shots with the DA*16-50 are on the flickr site listed in my signature, together with some other lenses and effects. Enjoy!

Thank you. Those are lovely. I hadn't considered that it is the same sensor, which would make it pretty similar. Also something I hadn't considered: I have some SMC Takumar lenses that I have yet to get an adapter for, a 135/2.5 and a 55/1.8. As the former telephoto Tak has the same focal range and aperture as the DA* lens at full zoom, would it be expecting too much of it to perform similar to the DA*? And would not the 55/1.8 be very similar to the F 50/1.4?

Minus auto-focus, of course. I still want the DA* 16-50.

The Takumars will work just fine on any Pentax camera. You will need an adapter to use them on a bayonet camera, of course. Try to get only the real Pentax version. Some of the third party ones do not allow the lens to focus to infinity, and others are a real pain to remove. The genuine Pentax adapter comes off with a fingernail.

The 135/2.5 SMC Takumar should give you excellent results. Due to the differing coatings, you will probably have chromatic aberrations in back lit situations, but that can be removed in post processing. My 400, for example just loves to give me lovely red borders on the images when they are backlit - on my Flickr site there is a portrait of a mule deer doe that demonstrates the flaw.

I had the 55/1.8 in the K mount version (same optical formula, different mount only) and it was a superb lens.

Welcome to the world of Pentax. If Pentax made the glass, you can put it on your dSLR and take pictures with it. There are even adapters for the 6x7 and 6x4.5 lenses.

Hi drewd,
Sorry, I can't post any pics at the moment. But I'd like to say that having exactly this combination (see my signature) I'm enjoying it, having a lot of fun. Unfortunately I didn't try any other similar lenses, therefore can't compare.
I decided to go with k200d vs k20d due to $$ limits: better have lesser body+better glass than better body+lesser glass.
As for FA50 1.4, I agree with many posters - it's one of the best lenses in terms of value.
Good luck with whatever you decide.

These are all from my K200D + DA* 16-50mm. Not too much use of f2.8, but some are and there is full exif.

Best filter for my Pentax 16-50mm ? what you guys have?

hi guys,

I just ordered my Pentax 16-50mm f2.8. I'd like to order my Filter now, but the store i ordered it had only Sigma and 2 others el cheapo filter. So i need a good clean 77mm filter.

Hoya, B&W, Sigma ? What did you put on your 16-50mm ?

thanks!

To filter or not to filter and if to filter which one?
I assume you are talking about a UV filter?
I say "no filter". Use a hood, save your money, get insurance instead and have better IQ.
