Nikon D7000 problems
Posted By gorski

I am planning to buy used body, so K5II is not really camera that I would consider. I do agree that K5 is in general better camera than D7000, I mean the fact that K5 is top of the line of Pentax dslr speaks for itself that is not crippled in any way. However (there is always however), body is not really the most important thing. The fact is that you have to choose the system and not just the body. I always buy used items, which I can test personally. And as you might know the Pentax used items market is almost non-existent in Slovenia. This is one of the more important factors, although not the only one. Third-party support is also important factor; Tokina makes very good lenses, but does not support K-mount. I do not want to start the battle of the systems, but the fact that




is why I asked on this forum. Pentax community is indeed very, I’ll put it this way, humane.

Nikon D7000 problems

I am considering whether to invest into Pentax system or to invest into Nikon system, which in first step means to buy either K-5 or Nikon D7000. I know what were in the past the problems with K-5 and I know which one were corrected. I also know that D7000 had its own issues. Beyond hot pixel issues I do not really know which the rest problems were. Could somebody give me a short list of the problems and if they were corrected or not.

I am sure that somebody will ask why I do not ask this on some Nikon forum, but from the post I read on this forum I believe that I can get a pretty much unbiased answers from members of the Pentax forum.

Did anybody of the Pentax representatives mentioned they will show updated roadmap. Roadmap could introduce more certainty what the future will bring and it would be easier to invest money in Pentax products.

Focus stacking...

Registax is for astro work. It would not know what to do with razor thin DOF macro shots. It would probably throw all of them out, because in general none would be sharp enough to include it into final stack.

You should avoid Tamron 10-24, it is very soft wide open. Sigma 10-20 f3.5 is fast and sharp wide open, Sigma 8-16 is also very sharp wide open, but it is a little bit slower. Sharpest and fastest is Samyang 14 f2.8. If you use it for architecture you can notice barrel distortion, but in landscape shots it is not something that you would notice.

AEB + Timer?
Posted By gorski

I am pretty much sure that timer+SR is not supported. When using a timer, it is expected that the camera will be in fixed position (on a tripod or at least put on something solid, table or a flat rock). However using timer + bracketing is something that K-5 supports and it is a fairly common tool for landscape photography, probably also for macro work. I am not really sure how much you gain, especially if lenses are not top sharp, but as I said it is a fairly common tool and not something one in a million user would need, so one could expect K-30 should support it. Seems that it does not.

So there is basically no options to make a mirror lock-up (which happens only when a timer is used) and make 3 bracketing shots?

K-30 Studio Samples Just Posted!

When I read your post I went back to the sample and I did check the sharpness of the object that are in the back of the scene. You are right, the focus point of K-30 sample seems to be a little in back compared to focus points of the other cameras. it also seem that for the K-30 samples dpreview used lens that has a better corner performance than lenses used on other cameras. Unfortunately, feathers and fuzzy balls are in front part of the scene and I made kind of wrong ascertainment.

Nevertheless, samples at ISO1600 look better anywhere in the scene no matter the place of the focus point. From the commercial point of view Canon 650D was established as a new benchmark for this class of dslr-s and if K-30 performs better in some aspects I am sure that it will gain wider audience, which might lead to a lower price of the K-30 in the future.

At ISO1600 K-30 has better IQ than Canon 650D, but at ISO100 a 650D shows better details than K-30. It is also noisier, which somehow implies that K-30 does some noise reduction at an expense of lower detail retention. Those who know how to do a noise post processing and shot at lower iso 650D (e.g. landscape photography) will have to do a little more research to choose camera if IQ is the most important aspect. Well in case of landscape photography K-30 should have an edge because of the WR.

Mirror lock-up

Thank guys, so this is the same as with the K-x. I did not check the K-r manual, but as far as I remember, the K-x manual did use the "mirror lock-up" keyword when referring to it in conjunction with a 2s self-timer. Strangely the K-30 manual does not mention it. Anyway, good to know that it is still there. Some would say that it is not a proper mirror lock-up function, but good enough for me.

Mirror lock-up

Does the K-30 have a mirror lock-up function? The manual doesn’t mention it, so I am guessing K-30 lacks the mirror lock-up. However, PentaxForums’ Pentax DSLR Comparison (Pentax Cameras | Pentax K-5 vs. Pentax K-30 vs. Pentax K-01 - Pentax DSLR Comparison - PentaxForums.com) shows that the K-30 has the mirror lock-up function. On the other hand, B&H shows that K-30 does not have mirror lock-up function (Pentax K-30 Digital Camera (Body Only) (Black) 15613 B&H Photo). Googling it does not give a definite answer on the mirror lock-up function.


Hence, I am asking here. Does it have the mirror lock-up or not?

So, K-30 DOES have focus peaking during video. I thought peaking option was available only during live view.

Is K30 "better" then the K5?

In practice it will probably mean a little less margin for extracting shadow details. K-5 is renowned for good retention of details in shadows, so the K-30 should nevertheless still have a noticeably better performance in that respect than other dslr of the same range.

Number of bits of the A/D converter (and hence the RAW) is a hardware thing, it cannot be upgraded with a firmware update. The image sensor outputs an analog voltage, which is proportional to a number of photons that hit the pixel, and this voltage needs to be digitalized into something that is interpretable to computers. A/D converter does that. The difference between the 12bit and 14bit converter is in an extra electronic circuit of transistors, resistors, capacitors, ... and this is on the lowest level of the hardware.

As you said, it is inherent to the design of the camera, and thus cannot be a subject to alteration later.

Is it possible that sharpening is applied to the K-30 raw files. Also looking at the noise, noise from K-5 seems finer, really each pixel to pixel, while noise from K-30 seems like it has larger "grain", which would mean that there is some kind of noise reduction, maybe very simple averaging. But this seems in contradiction to the fact that the images from K-30 look sharper. They seem more “punchy” than images from the other dslrs.

I am also in this boat.

I do not think that K-5 replacements will have the same history (well future) as K-5. The price drops would never happen if there would be no delays because of the flodings and Ricoh takeover. For a short time K-5 became the only dslr which would satisfy consumers wanting the mid-level and higher-level dslr. I think K-5 is exception that will not repeat.

That is good news, because then we do not need to wait for the focusingscreen.com to make a dedicated screen for K-30, but the screen for the K-5 can be ordered. Are you 100% sure that they look the same?

Wireless flash triggering on a K-30?

Thanks for the link, I did not expect a manual to be on the web before the camera comes to stores. That will help me answer my other questions about K-30.

Well, K-30 does support the wireless flash triggering. What it lack compared to K-5 is no PC X-sync port, but as far as I know adapter for hot-shoe to PC sync can be bought. So in practice this is maybe not so relevant.



Well, this is the answer I wanted to hear. Thanks

Wireless flash triggering on a K-30?

I have two questions regarding the use of flashes with the Pentax body.

A while ago I sold my K-x, and I wanted to buy a K-5. But then K-30 was announced and I decided I should wait, since K-30 might be more appropriate body for me. One of my plans for future was also to buy two flashes and to try to do some macro work with wireless flashes. So my first question is, do you think K-30 will support wireless flash triggering? As far as I read K-01 does not support this and it seems that K-30 will be a kind of brother of K-01. I would probably buy a Metz and a Yongnuo.

Yesterday I was surfing around, trying to find an answer for something not really relevant to flashes but I bumped into a thread on some forum saying that canon flashes can be used on pentax body. I did surf around and it seems that couple of people did try it and it can work. I find this very interesting. Unfortunately I cannot test it because I currently do not have Pentax body. I have an access to a Speedlight 580EXII flash and I can borrow it any time I want. So my second question is: could I use Canon flash and a Yongnuo flash (one mounted on the body and other one used as a slave, or even both as a slave) on a Pentax K-5 or Pentax K-30 body. I hope somebody could give me at least an educated guess since nobody can actually test it with K-30?

Yes indeed, sensor used in K-5 is the closest thing to ISO-less sensor. You should read the The "ISOless" sensor thread (https://www.pentaxforums.com/forums/pentax-k-5-forum/135603-isoless-sensor.html).

As far as I know the analog amplification goes up to 1600 ISO, while anything higher is in-camera digital amplification. So, there should be some advantage in raising the ISO to 1600, but not higher. There are also some indications that analog gain goes just up to 800 ISO (D7000 sensor trivia: Nikon D90 - D40 / D7000 - D3000 Forum: Digital Photography Review).
