An important message from the moderators

Every community and every institution in the world needs rules to function. We have a set of rules that are designed to provide a welcoming and friendly environment for people from all over the world who share a love of photography. The success of this forum in growing and in achieving its aims shows that overall the rules - and the tweaks to them along the way - have worked well.

Incidentally, "private forum" is not an oxymoron. Just because a private body has many members, and membership is open to anyone, does not change its character. Nor does the fact that the written contributions of members are displayed to the world. Members agree to a set of rules as a condition of membership. Membership can be terminated for breach of the rules.

The PF web site is, in essence, the sum of the written contributions of PF members and staff. In some countries, the publisher of a web site is legally responsible for contributions published on that site (regardless of where the site is hosted or where the contribution is made from). The operator of a private forum has at least a moral responsibility, if not a legal one, to prevent it being used for illegal or improper purposes. That is why there are rules designed to prevent, for example, bullying, harassment, sexual or racial abuse or the publication of nudity or sexually explicit material to minors. Such things are unlawful in many countries.


The point is that the forum will become a better place if the core principles embedded in the existing rules are observed and if the rules are applied more effectively to that end. The aim is to preserve and foster the distinctive culture here which has been built up over time through the contributions of thousand of people. (Including, I might add, yourself zzeitg - I mean, an average of three likes per post shows how much your contributions are valued.)

Transfer Non Digital Lens to Digital Cam??

Great to hear Bob.

Have fun with the lens. As a general rule these xx-300mm zooms need stopping down by a stop or two, especially at the long, for the best resolution. f8 or f11 is the way to go, whenever possible. Looks like that is where you are going anyway with the train pix.

Welcome to PF membership!

Is your lens one of these?
Sigma 28-300mm F3.5-6.3 DL Hyperzoom Lens Reviews - Sigma Lenses - Pentax Lens Review Database
Sigma 28-300mm F3.5-6.3 DG Macro Lens Reviews - Sigma Lenses - Pentax Lens Review Database

If it is, chances are, as others have said, that the problem is just that the aperture ring is not set to A.

There is another K-mount Sigma 28-300 model in the database:
Sigma 28-300 f/3.5-6.3 Lens Reviews - Sigma Lenses - Pentax Lens Review Database
From the image, it isn't clear whether this model has an aperture ring. (I have seen a similar looking model in Minolta mount on ebay which doesn't.) If it is this one, and it doesn't have an aperture ring, the problem is more complicated.

Can you post some images of the lens (use your phone if need be)?

I should warn you that it won't be long before we start suggesting that you upgrade to some better lenses!

I agree that it is very beautiful Tom. I'm told it's a 1958 Ford Customline. The ownership experience might have been less attractive. My dad (born in 1921) shared your dad's unsentimental view about old cars. To that he added a lifelong prejudice against Fords, based on his one-time ownership of an A-model!

How do I sharpen for Pentaxforums?
Posted By Des

I don't know why, but I always get better results by posting to Flickr and pasting the image from there (usually at 1024 pixels wide).

I haven't used PE so can't comment on that. But personally I rarely use the sharpening tool in my PP program (DxO PL3). I find that judicious use of the clarity tool, contrast and microcontrast create a more subtle appearance of sharpness. With a single subject (e.g. a bird) I usually leave the background with minimal treatment (sometimes darkened), mask the subject and apply clarity, microcontrast and contrast to taste.

1. The ergonomics will take some getting used to. (I still don't like them, compared to the K-3, K-30 or K-S2.) Try the different hand grips. I prefer the large (didn't come with my model; it was kindly supplied by a member here), but find even that too small. The shutter button is less comfortably placed than on the K-3.
2. Work out what you prefer to do with the third wheel. It is very customisable. I assigned ISO to the C1 setting and expected to use it constantly. But in practice I use TAv so often that setting the ISO is not the most frequent change I make (aside from aperture and shutter speed). I actually find the changes I make most are AE metering (AE on the mode dial) and AF active area (set to C2 on the dial). CH/CL allows you to toggle through the settings in the drive mode (for example, if the drive mode is set to continuous shooting, turning the third wheel toggles between H, M and L).
3. You can assign all sorts of functions to the other buttons. Frankly I can never remember which function I have assigned to which button!
4. I tried back button AF on the camera but I have switched back to shutter button AF. That is partly because I don't like the placement of the "AF AE-L" button but mainly because I mostly use focus point select and need my right thumb available to move the focus point.
5. You have to remember that Live View is selected with the On/off switch.
6. The tilting screen is quicker to deploy than the flip screen (which I have on the K-S2), but it is frustrating when the camera is in vertical orientation.
7. Shake Reduction is good for an extra stop or so over my other cameras.
8. Not sure what to think about electronic shutter. I only use it for Pixel Shift. YMMV. The mechanical shutter is much quieter than on the entry models (K-30, K-S2 etc) but maybe not as quiet as on the K-3 (?).
9. Burst mode is mostly adequate but lags behind the K-3.

For all its quirks and limitations, I use the KP constantly now. The IQ is excellent. It is worth an extra stop or two over the K-3.

That sounds like a good deal. Mine was theoretically covered by house and contents insurance but the excess was more than the cost of the lens.

You are not the only one to be inspired by Greg's photos.

Enjoy the PLM - it's an excellent lens for what it is. The only note of caution I would add is that its lightweight construction makes it easy to break: What to avoid with your 55-300 PLM lens! - PentaxForums.com

A question for 12-24 owners

It can be pretty bad. Here is an example at 12mm.
Unprocessed RAW conversion.


Crop from the top right corner


After processing (with DxO OP). You can still see the effects.


A pity, because I really like it for tall forest shots. Outside these sorts of situations, though, it's a good lens. Samples here: Pentax DA 12-24 f4 images - Des(Australia) - Flickr

I've used the 12-24 + 55-300 (sometimes plus prime) kit myself and it has worked for me. (Lately I've been seduced by the Limiteds and now generally carry 15 + 20-40 + 55-300.)

Not really a fair comparison. The Nikkor 500mm f5.6 PF costs about $A5,500. The FA*300 f4.5 goes for about $A750 if you can find one. The DFA 150-450 f4.5-5.6 would be a fairer comparison, but even that is a couple of grand cheaper than the Nikkor (around $A3700 and often on sale for around $A3200). I've never used it, but I see many fine images posted here with the 150-450.

For the OP, I suggest looking in this thread for images taken with the 150-450 and a TC: Post your HD PENTAX-D FA 150-450mm F4.5-5.6 ED DC AW pictures! - PentaxForums.com


You didn't say which 1.4 TC, but I assume you mean the current DA model. If so, see this thread for images and discussion: The Pentax HD PENTAX-DA AF Rear Converter 1.4X AW (and any lens) Club - PentaxForums.com

Edit: Here's an example with the FA*300 f4.5 + Kenko 1.5x TC (really 1.4x), mounted on the K-3. The EXIF says f5.6 (it ignores the TC), so effectively 420mm f8. It meant using 1/500th and 1600 ISO, neither of which was ideal. I'm guessing only about 6m-8m to subject, but the spinebill is quite small (about sparrow size). Using the TC meant only cropping from 24mp to about 17.7mp.


Whether I got much gain from the TC I don't know. If I were doing it again I might have skipped the TC and spent the extra stop on shutter speed and/or ISO. Of course if I had the 150-450, 450mm f5.6 would have been ideal.

16-85 off... other choices?
Posted By Des

That's a first. ;-)


As an affordable replacement for the DA 16-85, for the mix of travel and portraits, the DA 18-135 is the obvious choice, if you want WR and don't crave a faster aperture.

I would endorse Norm's point. Never mind test charts, this is a lens that produces very good results in real world use by any competent user. It has exceptional centre sharpness.


The colours and contrast are very good for a consumer zoom.


It even does pretty good landscapes, when stopped down.






But then, if you weren't happy with the Sigma 17-70C, maybe you are looking for something that doesn't exist in this price range.

Wireless triggers with P-TTL cababilities?

Excellent post @Morenjavi. Very informative. Just one correction here:

The Godox TT350P also supports PTTL on-camera. It can also be used as a controller for off-camera Godox strobes (with PTTL, HSS, etc). Apart from on-camera use, I also use mine off-camera controlled by an XProP

I wish Godox would release a PTTL version of the TT685 or V860ii as a more powerful on-camera (and off-camera) TTL flash that takes rectangular modifiers (I have a MagMod wildlife kit), to replace my Metz 58AF1.
