K-30 vs OM-D
Personally I think the title of the original post - K-30 vs OM-D - is a bit misleading simply through price differential if nothing else. A truer reflection would be two and a half K-30s vs one OM-D. I used the Olympus E-system for 5 years with the E-410, E-600 and E-3. I decided I wanted a smalle...

Prime lens wow factor
I've owned a few primes (FA 50mm F2, DA40mm F2.8, DA15mm, DA 35mm) and to be honest haven't really been wowed by any of them in comparison to the DA17-70 or DA12-24... the DA15mm I had was probably the nearest to impressing me, great colour/contrast but my copy had too much distortion at the edges. ...

Possible Fault
Have you checked that the contacts are clean on both lens and camera? Also, does it happen with just one lens, or with several? I've experienced similar with my Sigma 105mm DG EX Macro as it seems more sensitive to being mounted absolutely spot on than any of my other lenses, but I keep the contac...

I fully expect new models yearly.Very happy to chat now its a bit cooler in my front room. Whatever it is I'll wait a year and buy it at a sensible price if so motivated. I expect a 24MP 35mm sensor with a crop mode for us (relatively)poorer chaps who have DA lenses. It'll have a 1.4 mp ga...

Pentax are very good at pulling something totally different out of the hat. It could just be something we haven't even thought of and it could be amazing. John - going along with that "train of thought", imagine this "concept camera" having the 41Mp sensor that Nokia has in it's latest phone, Bill's...

What's interesting with digital developments now is the wider range of questions concerning model choices than during the 'film era'. I mean, with film, quality was determined by the film size, and lenses. Within the various film ranges the quality was fixed for any camera, and photographers cho...

Jules, thanks for those ideas on the quality issues with FF. I have always felt the number of photographers who would actually require the extra pixels and whatever else the larger sensor offered, would be fairly small. By 'require', I mean that there is no way they could produce equivalent output o...

I agree with most of your comments Jules, there's no doubt that some people get carried away with the promotional material/hype and end up with a camera that's beyond their needs. In fact I think people forget to read the spec of a camera before buying it, from what I've read about the technical det...

Heres' a chance to make myself look stupid - possibly :oops: but the whole full frame argument and limited depth of field seems to be counter productive to me for landscapes given the apsc extended depth of field at a given apeture :shock: I have read (I think) that the medium format lenses/syste...

DOF for a given aperture and focal length is the same regardless of sensor size. To expand on that so poor Stuey doesn't get confused: Smeggy is quite correct, the DoF in relation to a lenses focal length doesn't change, what does make the difference is that to fill the frame with the same scene ...

I see this more clearly now by way of explanation above and now that I have bothered to read up on the issue of full frame and depth of field :D Still seems bizarre to me then if you need a shallow depth of field for example it seems that a full frame camera with a 50mm lens at f8 will give rough...

IMHO shallow depth of field is more useful for portrait photographers, that's not to say landscape photographers don't use it but if you look around the web you'll find the vast majority of landscape images aim for maximum depth. I think the reason many landscape photographers have been attracte...

The fact that there is discussion about who would benefit ('.. a pro such as Simon is more likely to see the benefit...') demonstrates that the game is much more complicated then in earlier times. I mean, when I started out I had a budget, consumer-grade Canon (eos 300). But I could have been sta...

Itīs difficult to say, but Pentax already have 37Mpx camera. 645D :) Expectations are for FF 24Mpx :) APS-C could be 24Mpix too, but we do not have such a good glass for it. I am happy enough with 16Mpx... So am I. I have no desire to shoot landscapes that I can blow up to billboard size and t...

More often than not people swap systems, dump all their previous kit, then disappear, not a sweeping generalisation, just an observation. Done it enough times myself actually with all the Systems I've owned! :oops: Not everyone is the same of course I like Pentax's ergonomics and small size, If th...
