Pentax 50mm 1:2 SMC Pentax-M. Any good for portraits?
Apologies for reopening a wound. My thoughts were around the FF to APS-C conversions, and having taken some time to consider the concepts John and co have conveyed I can see where you are coming from. A different and more simple way to convey this could be: To achieve the 'most flattering' pe...

Let's please get back to the point. This is not helping any understanding of either the OP's question or indeed any other matters. Now I'll put my thinking cap on and we'll get a new weekly competition under way. Let's think positively and take the photography forwards.

Let's please get back to the point...... I think the answer is still "Yes" ;)

is a (potentially) useful piece on focal length and perspective as it relates to portrait photography. One can argue until the cows come home about the maths of it all and controlled tests. But in the real world then if you are after a head and shoulders shot then you will change camera position...

Pentax 50mm 1:2 SMC Pentax-M. Any good for portraits?
There is clearly two different aspects here, with terminology blurring between the two. One is the physical viewing lines based on distance/position to the object. This dictates what is physically visible for a fixed given location, ie can't magically see around corners etc. The other is th...

Pentax 50mm 1:2 SMC Pentax-M. Any good for portraits?
Never noticed how things towards the edge of the frame get a bit stretched and distorted on a uwa lens? That's perfectly normal for an UWA lens. Circular objects often appear oval. It isn't a fault and shouldn't be corrected.... it's the view. WA views very often have all the Intersection Points wi...

Pentax 50mm 1:2 SMC Pentax-M. Any good for portraits?
That's all marketing, snake oil stuff. Bit like selling a watch that doesn't work and saying it's spot on twice a day. It's very confusing and because of your original post about the Photozone article i.e..... "Whoever wrote that PhotoZone article needs a good slapping, and his computer confisc...

a quick technique for grip improvement.
For modest lenses just pass the strap round the back of your head then twist it as many times as required that a final twist with your right hand effectively clamps the camera to your face. Not for every day shots but a very useful technique if you need to use a fairly low shutter speed! With film c...

K-3 exposure
Malcolm, you say " ... K3 it is that it is more inclined to blow a highlight than the K5" ... I guess this may be my point. If the photowells have less capacity, because they are smaller, then they are more likely to blow, are they not ? Maybe then the metering software, effectively, "sees" the ...

K-3 exposure
Exposure is a really subjective area (unlike 'sharp' focus for example). Multi-segment metering is a world to itself and you've no idea what the camera is compensating for (or not). From the spec, the K-3 metering sounds much more advanced than the K-5 and it wouldn't be a surprise to find that they...

My K-3 review...
Some remarks on the settings, which might be useful: "Bright" (default setting [!]) and/or "Extra Sharpness" should be avoided when using high ISO numbers (see image below). I mainly used as standard: - 2: Noise Reduction - Custom ISO 0100-01250 - OFF ISO 1600-02500 - +1 ISO 3200-05000 ...

Asking a favour form anyone who owns a K5iiS and a K3
Hi Jonathan I also have both cameras and could do the tests if no-one else has or cannot do so for whatever reason. Unfortunately I live in the back of beyond with minimal light pollution but could try to photograph my house from the outside with lights on internally if that would be of any use....

Asking a favour form anyone who owns a K5iiS and a K3
Hi folks, due to continuing computer problems (still not got a replacement fan) I can't run DXO Optics Pro on my computer at the moment without it overheating, so my experiments with RAW files have been somewhat delayed. From the few I have managed to process, there's very little in it as far as the...

Asking a favour form anyone who owns a K5iiS and a K3
I could argue that correct exposure and sharp focus are equal parts of the image quality pipeline, which is why in real use I'm finding the K3 a little better I think than the K5 because the K3 seems to pretty much nail both every time requiring less PP, which I also like (Not at the moment though I...

Asking a favour form anyone who owns a K5iiS and a K3
Jules, having returned to using the K100D recently from the K-30 I do agree with the focus comments. I don't really think there is anything faulty with my camera, but more the focus systems have improved significantly since those early days. Exposure potentially is irrelevant if you're using ful...

Asking a favour form anyone who owns a K5iiS and a K3
The K30 is a real winner, no doubt, despite looking like a Nike Traning shoe! Personally I feel that being able to print bigger with the same/similar (For you Smeggy!) amount of noise is a win but I'd agree that the Bayer arrayed APSC Sensor has hit a buffer, will the next generation employ the sam...
