well, I was actually searching for someone who tried in order to confirm what works or not before I buy anything :)

I imagined some Ricoh GR addicts would have gone the same way when upgrading their camera

GRiii compatibility with old GH-3 & GW-3 wide lens kit

I own a Ricoh GR (the first APS-C model) together with a GH-3 adaptator and a GW-3 wide lens.

I am thinking sell sell the ricoh to buy the new GRiii version.

Can you tell me if the GH-3 and GW-3 will still work on it?

I find contradictory infos about this.
It seems the GH-3 wont work (too short apparently) but the GW-3 will work (with a proper longer adaptator).

I know the GW-4 would be ideal but that's plenty more money on top the GRiii :eek:

the second set of pictures (2 dogs) seem too much identical to me:

Exactly same perspectives, dogs didnt move at all, I dont believe this was taken by 2 different cameras.

What do you think?

Im looking for a pocketable good camera and this GRD seems very interesting.

However, how does it compare with the Sony RX100 ?

Is the sensor size difference that much in favour of the GRD ?

what if you were using a compact camera?

everybody knows that a good photopgraph would do a better job with theses that a beginner with a FF.

Would you still feel offended ?

Once you're a know photograph, you can photograph with everything you want, even a compact.
But since you're unknown, you need to make some points and equipment you use is one amongst others.

To this flash buyers, i would like to know if, when ordering it, you need to specify you have a Pentax camera, or if thsi flash is compatible with all systems (pentax, nikon, canon).

That would be nice since I'm also looking for adding a Canon FF to my gear.

Extension tube question?

Hi Littledrawe,

Nice to see your post :)

I actually have exactly the same extension tubes, found second hands for few bucks recently, and also had trouble in making a proper macro picture.

I used a manual facus pentax 50mm /1.7 A lens for that, and I noticed that I can not set the aperture (manually on the lens or via the camera in Av mode) as required.

When mounting the tube on the lens, everything looks ok. Moving manually the small metallic "finger" (what's the name in english?) would trigger the diaphragm properly.

But when I mount the lens+ tube on the K5, while turning to fix it, I can see the diaphrag opening as wide as possible (so it sticks f1.7) and nothing can be done to close it.

I guess that what you have too, overexposure because your lens is actually opened at its maximum and not at the f16 value you set.

If somebody knows how to fix that

k5 vs 5Dmk2 autofocus
Posted By oliver939
Replies: 19

I am a k5 owner but since the recent canon news (5Dmk3), I'm finally looking toward buying a fullframe 5Dmk2 (second hand) that are becoming more and more affordable now.

The main complaint I could read about the 5Dmk2 is its autofocus and I''m wondering up to which extent does the 5dmk2 can compare with a k5 autofocus.

Is it comparable, is the 5Dmk2 much faster (but so-called slow for a "pro" FF camera) or is the k5 faster (being a much recent product)?

Sorry to ask this here but I'm sure more people know teh 5Dmk2 here that people know teh k5 on a canon forum :rolleyes:

Thanks :cool:

Diy tracking tripod platform for astrophotography

the main issue with such devices (and even with a proper equatorial mount) is to set them up correctly to align with the earth rotation axis.
It is easier and more accurate with some equatorial mount, especially is you have a telescop that you can use to correct the drift.

I built few of them while still using film cameras but having a k5 now, I would give a try to the easy Pentax O-GPS1 solution :)

if pentax could also "compensate" meaning produce a Full Framce camera (such a the D4 or the 1DIV you compared the k5 with) I wouldnt mind...

never heard this reason but it sounds like good one, although in my case I would privilege the disk space rather than camera CPU.

Would you know the values for a K5?

Exposure With Neutral Density Filter
Posted By oliver939
Replies: 4
Views: 1,568
with such filter, the exposure cell sees barely nothing, so it can not calculate properly the correct expo settings.

Anyway, you need a tripod first.
Take a pic without teh filter (check the focus and the xpo settings).
Set the focus on manual (readjuste if necessary).
Put the filter on the camera
Set the iso and/or the diaphragm and/or the time in order to expose 10 times more in comparison to your first pic.
Then you should have correct exposure.
Sometimes, some more finetuning will be necessary (add or remove few Ev).

Landscape Astrophotography - Horrid Noise (K100D Super)
Posted By oliver939

I'm an astrophoto guy and had a k100Ds and I can tell, although I love this camera, it is not veyr fit for astrophoto.
It always make a lot of noise (I tried whithout NR and then apply a dark but not enough) and banding.
But still, in your case, I would try to reduce the iso to 400, disable NR, make a dark and stack several image together,

in my case, now, I have K5 and it's like night and day.

But anyway, in general for astrophoto, you need to pp your pictures, they'll never look very nice without proper processing.

regaridng the equatorial mount, it's another subject (to avoid star trails) and will not improve the noise.

personnality , i dont like this new look at all.
the light color of the green over white page is difficult to read
the fonts use do not show up nicely

i dont mind a new look but this need some improvement IMHO. it would be interesting to see the forum visit statistics since it has been implemented (i was so disturbed that spend less time here recently).

now i understood there's a way to switch back to old display, i'll try and hope it works :)
