Our Great Photo Processing Shootout!
John, as you quoted, I said 'in ACR'. My claim was restricted to, and was about the RAW processing stage only - that is specifically the more limited controls available in ACR for saturation & vibrance control, which are applied globally through single sliders. This stage is critical, because it...

Our Great Photo Processing Shootout!
In some small way I feel partly responsible for this thread since a couple of weeks ago I posted the question "Does anyone know of a tutorial for PCU4 ?" Nigel was kind enough to respond that he likes it and would help by posting some advice on its use. The rest, as they say, is history ! Ho...

Wow - removing image blur - the future
Absolutely not. Better to learn how to take a sharp photograph. I agree before long you will just have to go out point the camera and press the button, come back and focus it then do everything in mega photoshop/lightroom/topaz/gimp/picassa/paintshop probably missed a few it will come to the poin...

Looks handy, you'd have thought a camera brand might have developed this and stuck it in cams. Strictly a shake thing though, not sure if it'll do much to properly out of focus shots. Makes you wonder what the CIA's imagery tools are like :)

Product Registration
The dealer stamp isn't an issue, as you can (or could) register on-line. One upside to registereing kit was that you receievd a discount voucher back against future purchases. Dob't know whether Pentax Ricoh do with on-line registration or discounts.

old lens on new camera ?
Welcome to the forum. Your old lenses can certainly be used on the present cameras. If they are FA, F or A lenses, they work fine. (only the FA & A lenses auto focus of course) If they are M, K lenses, they can be used in manual mode. If they are 42mm mount they need an adaptor and can be u...

Thanks Vic. I do know A lenses don't auto focus, its the typing I don't know how to do!:oops: The A was meant to be an F but obviously the brain and fingers were thinking of something else at the time.:D

Quick question - do you get a focus confirm indication when using a manual focus lens? Thats one of the things that really annoyed me on the Olympus range, I couldn't see any reason why it couldn't be done in the software and focusing by eye on a digital viewfinder is tricky.

Quick question - do you get a focus confirm indication when using a manual focus lens? By using the green hexagon in the viewfinder. When it's steady, the camera is telling you things are in focus. If you have the camera set to MF that's it, job done. If you have the camera set to AF with a manua...

Thanks John. The focus trap sounds useful as well. Algy, no I *didn't* get confim on the olympus bodies. What was even more annoying was that if I used non-olympus lenses with an adapter I could get focus confim (using the right adapter with a chip in it) but that wasn't possible with olympus ...

I understand now :D The Green Hexagon/Beep will work in a fashion with most lenses. It's been there since the ME-F came out in 1981 so only 31 years old and far too young an implementation for any Pentax user to know much about it.... Can you come back in 20years? :shock: :wink: From tests ...

@Algernon How can you possibly get misfocus with LV and zooming? Isn't LV just an EVF in the sense of WYSIWYG? Like all things LV has a DOF and the aperture changes depending on the light level. Most of the time I have about +/- 20mm or 40mm total DOF and by definition (of DOF) it will look in ...

Anything optical has a DOF even your eyes :shock: Look at an object on the horizon with one eye and then hold a finger an inch in front of your eye and it won't be in focus. Your eyes have a greater DOF during the day than at night. It really is very basic optics.... any lens can only focus o...

OK you say you focus by looking at the screen. I presume that if you were using a preset 85mm f/1.4 lens you would open it up to wide open to focus, but would be quite happy to frame the picture at say f/8..... Why don't you also focus at f/8 Could it be that the DOF is too great at f/8 to focus...

The flat area of the graph at the bottom of this page shows quite clearly that there are several positions of the camera where electronically the camera looks in focus due to DOF. It covers about 4 rail positions. The article also explains why non of the methods are reliable. http://www.sl...

Why don't you also focus at f/8 Could it be that the DOF is too great at f/8 to focus properly Partly that reduced DOF at wider apertures makes the image snap in and out better and partly because a very dark image, such as when stopped down, is too dark for the eye to judge anything. You've move...

SnoozeMoose - I was talking about using an olympus DSLR body - I was hoping, and sounds like it is the case, that this issue will go away with the Pentax Body. On the Focus/DoF issue, I think that you need to go back to the circle (sphere) of confusion (or do we have enough confusion?) and accept...
