Resolution question
Biggest change I could see is a signal to noise ratio. Make bigger pixels and you've got more area to capture light, so you should have a stronger signal level up above the noise. Best example of this would be a cellphone camera, potentially 8MP or so, vs a APS-C or FF camera of the same resolut...

Resolution question
yes, good points thanks Richard . So poorer low - light performance and it would be harder to get very low depths of field on the smaller sensor ?

yes, good points thanks Richard . So poorer low - light performance and it would be harder to get very low depths of field on the smaller sensor ? From my point of view, these are the only two practical points that I think matter. It's not limited to m4/3s either, as the discussion is equally rele...

Cost of ownership
It's funny to see the initial focus on a camera body change when you realise that a system (camera plus lenses) consists mostly of lenses that will stay with you for a long time, and cameras that will be upgraded every so often. People new to this field tend to see the camera as the main focus, (h...

Experiences converting slides to digital
A dedicated film scanner is the best way to go for quality, although some of the cheap scanners (which don't actually scan but have a 5MP sensor) could be good enough for your requirements. Others will come up with some specifics. The cheapest option of all would be my old Panagor Zoom Slide Duplic...

Experiences converting slides to digital
I shot slide film almost exclusively for years and have many thousands of them. As a result, this is a subject I have some real interest in. If you don't have many, there are as you know, companies who will convert them to digital images for you. One of my local friends - not really into photogra...

Pentax Q 06 zoom....Impressed
Those really are stunning images from such a small sensor. Which model of Q are they taken with? :D

Pentax Q 06 zoom....Impressed
Those really are stunning images from such a small sensor. Which model of Q are they taken with? :D Thanks, these were taken with the original Q. I have the 01, 02 and now the 06 lenses, all are good but the 06 is a cracker! I am constantly surprised by the Q's tiny sensor and the quality it...

Pentax Q 06 zoom....Impressed
I am constantly surprised by the Q's tiny sensor and the quality it's capable of. Yep, same here. It's a magic little camera, and that magnesium alloy body makes it feel serious as well. I also have the 06 though I find I rarely use it, favouring the 01 prime most of the time.

If you thought only Pentax had bad QC
I thought Nikon had admitted the d600 oily sensor problem by repairing and or replacing those d600 with d610. Mine did suffer a little but once cleaned hasn't done it since. My af-s 85mm af didn't work out the box and took three returns to get working again. Once they did fix it it's great. I ...

Lytro & Modulo
The way technology jumps forwards in leaps and bounds how long will it be before there is a camera with both of these Inventions/Developments built in? If it's on the shelf today it's out of date tomorrow. (Not obsolete) but definitely out of date. How long before all cameras have night vision bui...

manual focus screen
Most mirrorless cameras have a sensor/mount depth that allows for adapters to use a multitude of legacy lenses. I've heard nothing but good things from users with regards to MF lenses on these; with the focussing aids mentioned above offering a much better experience over the optical viewfinder alo...

manual focus screen
I bought a Pentax mount for my Olympus EPL1 and it woks just fine but, to be honest, this makes the whole set-up unwieldy and in a way makes a small camera pointless. There's also the annoying extra crop factor if the camera's sensor is micro 4/3. Even a 28mm becomes, in effect, a standard lens. So...

manual focus screen
Focussing scales have never appealed to me. They're present on the better lenses, but I personally don't use them. I see one new lens came out recently with a digital focussing scale on it... When my Aperture motor failed, I became acutely aware at how few modern lenses have a dedicated apertur...

HCB was a great, no-nonsense photojournalist, one of his books has some shots with the film perforations running across the photos ('Lomo' style), quite how he manged it I don't know. That said, apart from the shot of the guy jumping over the puddle mirroring the circus advert behind him, most that ...

The 'decisive moment' was apparent in a number of H C-B's photos, but I am sure that at least one was set up: a running girl caught in a ray of sunshine in a shadowed italian courtyard. Anyhow, it still works. The photo at the top of this thread would not be very memorable if it's just of some old b...

Be prepared!
The problem is that some quality compacts are not very compact. A few years ago I bought a Canon G12. Loads of features and decent build but it is too large to fit comfortably in a pocket and still has the limitations of a small sensor. I still have it but it gets little use nowadays. I have a Penta...
