Best lens pairings for new APS-C?
Posted By sungibr

Regarding autofocus, I think the only lenses that would take full advantage of the AF capabilities of mkIII is the new DA*16-50 and the 55-300 PLM.

All those modern D-FA should do fine, but they are not as fast as those PLM driven lenses.


DC lenses should be also OK.


Screwdrive lenses will be what they already are with current cameras.

Wild rumour/wish fulfillment fantasy about new Pentax film camera?????

Just thinking:


Isn't there another rumor floatting around that said ricoh is planning a video centric DSLR camera?
What if the rumors was caught wrong, and started as a 'film centric camera"? Or a film SLR, but people just assumed it was obviously about a video DSLR?

I don't think is the case.
My bet is it'll still have dual SD card. But really hope for at least one UHS-II

Use of EV button in manual mode on K-3

Well, I'll assume the EV button you're refering is the +/- button besides ISO button.

It does work in manual, but not on exposure, but on metering.

Holding it and turn the rear dial will affect the zeroing of your metering and the base exposure for the green button press.

Of course, if you set exposure manually, pressing it and changing settings won't make the camera change exposure, but your metering will change.
If you think about it, that's how the camera sees the scene when you set a compensation. Then it will set exposure accordingly, just as you would manually.

It all comes down to how you like to photograph.

By the way, this works on K5 series too.

Could it be the AA filter simulator ON?

I believe mine does some high frequency sound when it is turned on, just in the moment you drescribed. I never use it, but turned on a couple of times to compare how it affects pictures.

Where to find AF contacts

I guess I was th guy who might have bought the last two of then, sorry :p....

But, I wanna say you did a smart workaround on your lens, I never thought of it. My 16-50 brooke its contact YEARS ago, but it's hacked to screwdrive and works without it.

I know it is not the ideal solution, but you could do the same. The DA 300 can be hacked to.

PS: I do miss the silent AF, but screwdrive is more reliable on those DA 16-50mm lenses

I'm with you on that. Many users are reporting this same problem recently. Even with the very brand new D-FA* lenses. The Sigma contacts is also much more tough.


The pentax one is a really sloopy design

Back button focus + AF Select workflow

One other option would be detach AE-L from AF lock, use multi Multi-segment. If you are using a K3 it's pretty accurate.
Focus what you want, either by focus recompose or AF-sel, and let the camera meter by averaging the scene.
If the subject you are trying to capture are to much dynamic, locking exposure might lend to exposure error.
Or, if it is more or less static, you can shot manual, use green button to snap the exposure and shoot whatever focus mode you like.
So many options.

A question for silver K3 owners.

Hi.

I have one with me now. Take it with me pretty much 24/7, since I bought it, from a very good reputation guy I known, early last year.

I don't know what was the serial numbers that's supposed to be mirror-flap free, but mine is 25785XX, and I have had this issue a two or three times last year. I'll ad that I use this a lot for PJ work, and it never caused me to stop working.

When I bought the camera I udapted the firmware right away and that seems to work really well to counteract the issue, because the camera really stop the flapping when it occurs. The only real problem is that you lost the images you might be taking when it does.

To short, it happnes, but with very little frequency. Almost none, or none you could even notice.

Also, the actual fw is 1.40, and appears it make the occurency of the mirror flap even more controled, because I can't remember the camera doing it in the last months...


Hope it help.

HD Pentax-DA Fish-Eye 10-17mm f/3.5-4.5 ED

From my experience, most lens will vignette a bit. What I believe it's most important is how much a photographer will think it's acceptable.

People who have sawned and used the da10-17 said it's been quite usable, with accetable vigneting.

Also, vignette is the most easily corretable aberration in a lens.

Seems like Ricoh redesigned the hood to make it work with the K1 in FF mode. And prevent people to saw it of :D


This one at least have more redesign than just the HD coatings on the FA 35.

DA* 16-50mm F2.8 ED AL [IF] SDM as a screwdriver-only travel zoom?
Posted By sungibr
Replies: 15

Apart the weight, wich is almost the same as the Km, it might be a little short on tele end, as 50mm, depending on what kind of things you want to photograph.

Still, the 16mm settings is quite nice to have and reasonable wide to capture a lot of things that need a wide angle lens. And image quality is more than adequate to your camera. The f2.8 helps a lot to.

And in a bonus, you won't have to worry with the lens failing in the middle of the trip, as it will be a screwdrive.

If the price is really good, this will be a fine purchase anyway.

Best K-5 settings for smaller file sizes? Trying to set up DIY photo booth

Isn't there any mini HDMI - lightning cable you could use to set the ipad as an external monitor? I would look in to that.

As for the quality, I used to develop RAW in camera and export then to a mobile with an eyefi card, using the 2mp+4star quality, just to post it to Instagram, and that work just fine on smartphone screen and even print then in 4x6, so I think this will do just fine for you if you still wanted to send then wirelessly to the pad.

Never had this problem with mine K3 ltd silver, wich is less than a year in my hands and now with fw. 1.4. And I abuse it a lot, plenty of shoots in cont H.

Is exposure linked with af point?
Check Custom menu pg 1 item 5.
Usually, I let this option turned off, in matrix meter and focus sel.

70-200 AF issue
Posted By sungibr
Replies: 10
Views: 920
Happy to know it was "just" this. But my opinion is this is one design flaw. As I noted, it has happened with a brand new D-FA* 50mm (can't find the original post). And also with my 16-50 (broke the 2 contacts altogether), although this one is 7yrs old and hacked to screwdrive, so no problem doing AF.

I'm keeping eye on this 70-200 lens, cos I planning to buy it someday, but here in my country we have none pentax servicing for newer lenses, so reliabillity is a concern.

Glad to know, failures are really unlikelly with those now.


edit: I was thinking...maybe one could put a very little drop of superglue BELOW the contacts, to fix it in place and diminish the odds of then to bend over again...should it work?

Its a long shot, but, the SDM contacts are intact? I saw one guy who bought a new D-FA* 50mm that had the contacts of his lens broken.

And what you mean by "pepperberry farm? I'm not northamerican (nor english native) and was just curious about what that means.

Lens roadmap: Tanaka-san spills the beans

I quite like mine 16-50. Use an abuse it a lot. Like the sharpness, but CA is really ugly at wide settings. But I don't think turn it a 18-50 would cure those optical problems. I'm sure Ricoh can design one 16-50 with a much better control over aberrations.

Besides that, 16-something is an ideal range to a standard pro-grade zoom lens, and I think it wouldn't dissonates all that much overlaping with the new 11-18.

But if all they could do was updating its design with a much stronger body and better af, I think that won't be all that bad. After all, the problem that really turn people away from the original DA*16-50 was the bad SDM. And as soon as we discovered that screwdrive conversion hack, suddenly the lens got its value back.
