Re: Coolpix P5000 - 1 CAT

Glen,

Tabby looks great! (Looks like my cat)

To my eyes, most P&S cameras do well with portraits. For me, the real test of IQ is landscapes or architecture. Getting some real distance between the lens and a subject with fine detail will better tell the tale.

Any chance of a few landscape pics?

Thanks for posting.

Re: Lovely IQ for a P and S..This is going to be a winner of a cam! (nt)

I think it is.. Having also an Olympus 800 here also which I have always loved but lost it to the wife I think the new P5000 has potential for great things.

Add to all of that the fact that any of my 2 SB800s can be used on this I will certainly have fun.

My usual subjects are fit, trim in simple things... so off I went to see if I could do what is being asked for, well out the front door is nothing but cars so I wne to my back yard and this is my version of Landscape (for what it is worth).

Turned off flash, set to M, 1/60 - F:4.3 the proceeded to do a series of ISO tests, AutoWB, 400/800/1600 (all hand held - the damn this fits nice in my hands).

ISO:400 (this one was a bit different ??)

Original: "

"

ISO:400 (stooped to shoot the rest)

Original: "

"
ISO:800

Original: "

"
ISO:1600

Original: "

"

I will see how it takes on my D2Xs and D200 this weekend in the studio with it "my type of landscape".

Shutter lag is not bad, recover for next shot is decent.

  • Using a 2GB Lexr Pro (133x) memory card.

  • Added a second battery (just in case).

  • Lowepro Rezo 50 Camera Bag is what I choose to harness the beast.

Dead pixel?

Dead pixel? right lower corner, on the grass you got a white (red cercled) pixel, in all shots... I believe.

Strange images... after the one of your cat (sharp & plenty of details), this serie, noise, unsharp and lacking contrast?

ISO and VR Test - Re: Coolpix P5000 - 1 CAT

Michel Cojan wrote:

That was at ISO 64, and with Flash.

this serie, noise, unsharp and lacking contrast?

This series was supposed to test ISOs - High ISOs like ISO 400, 800 and 1600. Of course the images won't look as good (as images taken at ISO 64)

And, they were all taken under the manual mode at the same 1/60s and the same f/4.3, but with the different and various ISOs. The exposure couldn't be right. Contrast (and sharpness) could be affected too. Actually, it seems to be bright enough that ISO 400 was not even needed. Again, this was meant to be a test for ISOs.

It is not easy to design a test to check out P5000's ISO performance.

It would be more interesting to do the ISO test again under a dimmer or darker situation:

*********************

Use A mode. Use no Zoom. Under a dim or low light situation. Hand-held shots.

Initially set the manual ISO to 200.

Find an Aperture that will require a shutter speed about 1/10s for a proper exposure. You may have to choose a proper low light condition for that to happen. When you find that Aperture to have 1/10s at ISO 200 for a proper exposure, please fix at that same Aperture through out the test. Say it is f/4.

Now, we get Aperture out of the way.

But we are staying under A mode and that same fixed Aperture f/4 (or whatever)

Take a picture at 1/10s, f/4 (or whatever fixed) and ISO 200

Switch to ISO 100. The A mode should now choose 1/5s for the same scene.

Take a picture at 1/5s, f/4 and ISO 100.

Similarly,

Switch to ISO 400. The A mode should now choose 1/20s for the same scene.

Take a picture at 1/20s, f/4 and ISO 400

Take a picture at 1/40s, f/4 and ISO 800

Take a picture at 1/80s, f/4 and ISO 1600.

**********************

This test will show various ISO performance for about the same exposure. It will also show how good P5000's Vibration Reduction is for hand-held shots.

Forgot to ask to do one more thing - probably the most important thing for this test:

While staying under A mode with that same fixed Aperture (f/4 or whatever), and for the same scene,

please switch to Auto ISO and take one more picture.

Please find out what ISO the Auto ISO would pick and at what Shutter Speed.

We know the ISO will be 800 or below since ISO is capped by Auto ISO at 800 under P A S M modes.

More simple tests may be needed based on the answer:

If Auto ISO chooses ISO 800 at 1/40s (and f/4), we may want to find a slightly brighter scene that would do manual ISO 800 at about 1/80s (and f/4), and another brighter scene with manual ISO 800 at about 1/160s (and f/4).

Then switch back to Auto ISO and see what it will pick for those 2 additional brighter scenes.

Thank you very very much in advance.

An ISO test was being carried out.

Overcast conditions, Manual settings, kept the F-Stop at 4.3 and Shutter at 1/60 and adjusted ISO for the various shots, no other settings invloved.

Re: Pls Check out Auto ISO - Re: ISO and VR Test - Re: Coolpix P5000

No flash is assumed, however today is a bit of rain outdoors so we will see.

No A priority had been used all settings were M (everthing I normally do is M) but will try to pull off these tests.

M Mode - Re: Pls Check out Auto ISO - Re: ISO and VR Test - Re: Coolpix P5000

Thank you very much in advance.

To test higher ISOs, VR (at slow shutter speed) and Auto ISO's Minimum Shutter Speed, you can do it indoors. It may even be better - dimmer and easier to maintain the same dim lighting throughout the test.

No A priority had been used all settings were M (everthing I
normally do is M)

Can you do Auto ISO with the Manual mode? P5000's Manual mode does let you set all the manual ISOs or use Auto ISO (with 800 cap) too, right?

And you can see the proper exposure or not from the Exposure Display when adjusting either Aperture or Shutter Speed in the M mode, right?

If so, and if you like to do only M mode, the M mode test would be the following (but it won't find out the Min Shutter Speed for the Auto ISO - have to do the A mode test for that):

*************************************

Use M mode. Use no Zoom. No Flash. Under a dim or low light situation. Hand-held shots.

Initially set the manual ISO to 200.

To make things simpler, set Aperture to F2.7 (wide open with no zoom) and keep it there for the entire test under the low light situation. The only things left to set or change are ISOs and Shutter Speeds.

Find a low light situation that will require a shutter speed about 1/10s for proper exposure (Exposure Display = 0) at F2.7 and ISO 200.

Take a picture at 1/10s and ISO 200 (and F2.7)

Switch to manual ISO 100. You may now need to change Shutter Speed to 1/5s for proper exposure (Exposure Display = 0) for the same scene.

Take a picture at 1/5s and ISO 100 (and F2.7)

Similarly,

Switch to manual ISO 400. You may now need to change Shutter Speed to 1/20s for the same scene for proper exposure (Exposure Display = 0).

Take a picture at 1/20s and ISO 400 (and F2.7)

Take a picture at 1/40s and ISO 800 (and F2.7)

Take a picture at 1/80s and ISO 1600 (and F2.7)

While keeping the same exposure: Exposure Display = 0

Almost done

***

Please switch to Auto ISO for the same scene and lighting condition while keeping Aperture at F2.7.

Now try pick different Shutter Speeds and watch the Exposure Display. Is Auto ISO able to maintain the same proper exposure, Exposure Display = 0, by changing ISOs?

Is the ISO capped at 800 under M mode's Auto ISO? If so, you will notice that when you get the Shutter Speed up to a certain value, the Exposure Display may show under exposure and won't move back higher (by Auto ISO since it may be capped).

Please take a picture at a shutter speed just slower than when that happens (Exposure Display still = 0). Find out what the ISO was chosen by the Auto ISO and note the shutter speed that you pick.

If Auto ISO chooses ISO 800, that may confirm the 800 cap.

And say it is Auto ISO choosing 800 at 1/40s (and F2.7), we may want to find a slightly DARKER scene that would require manual ISO 1600 at about 1/40s also (and F2.7) for the proper exposure (Exposure Display = 0).

Then switch back to Auto ISO, and see what ISO it will pick for the DARKER scene when you keep the shutter speed at 1/40s (and F2.7). It should be Under Exposed at ISO 800. That will confirm the 800 cap (or not).

***********************************

As I said, you may have to use the A mode in order to find out the Minimum Shutter Speed for the Auto ISO.

In the A mode, the only thing you set and fix is Aperture. Both Shutter Speed and ISO (if you choose Auto ISO) will be allowed to vary. There may be (or should be) a minimum shutter speed for the Auto ISO. In other words, Auto ISO may try to pick the lowest ISO while maintaining a certain Minimum Shutter Speed (suitable for hand-held shots) in A mode.

In the M mode, the Shutter Speed is also manually set and Auto ISO (if there is one) becomes limited. The Auto ISO can't affect the shutter speed since the shutter speed is set by you.

Sorry for the long post.

but will try to pull off these tests.

Thank you very very much in advance.

Glen - S Mode Auto ISO - Re: Coolpix P5000

Hi Glen, or any other enthusiastic and helpful P5000 owners:

While you are at it, could you please also check out how Auto ISO under S mode works, assuming there is Auto ISO under the S mode?

In S mode, you would choose and fix the shutter speed (please try the slow ones like 1/5s, 1/10s, 1/15s, 1/20s, 1/30s, 1/40s, 1/50s ... etc under a low light no flash hand-held situation with still subjects).

(VR should be automatically on. Don't need to pick the Anti-shake mode to turn on VR. And please don't pick Anti-shake or Hi ISO mode. No need to freeze moving subjects here. The ISO will be too high.)

In traditional S mode, ISO is fixed also and the only thing varies will be Aperture for the proper exposure. Now Auto ISO can change ISO too. So what gets the next preference after the shutter speed under P5000's S mode Auto ISO?

Thank you very much in advance.

ISO-VR Test for w3 and others

Okay, here is what I have done.
http://www.zenfolio.com/ggrant/p1006985368/home.aspx

The subject (a bowl of plastic fruits on my table) low light, source of all light being a shutter blind camera left, hand held.

Auto ISO selected I "believe" yielded 1 of the ISO 800 shots (I never did a camera check at the time).

I hope this helps for now and will attempt to get the other tests done as requested.

All hand held, same subject, changed angle a bit a bit more light in room at time of shooting but not much (reflective from glass cabinet).

Hope this helps.
