Sorry, but no -- since you haven't used my model camera, you're just guessing -- there can be and *are* considerable differences between similar models from the same manufacturer. I know because, unlike you, I've used so many of them. >BTW: I did not make the statement you wish to attribute to me - I use both >DSLR and compact, choosing according to my needs at the time.

I have no such issues. Again: I say my compact digital works better for me than any dSLR i've tried. You say your dSLR works better for you than any compact digital you've tried. Both are equally valid statements. Neither is any sort of universal truth. -- Best regards, John Buying a dSLR doesn't make you a photographer, it makes you a dSLR owner.

Several models from the Panasonic range. Not "tried" as looked at in a shop once, but "used" as in being the main camera for several years. Again: I still use both DSLR and compacts, according to my needs at the time. I have not chosen one over the other. I accept that both have different advantages, do you? Cheers, David

It's not impossible to have a mechanical zoom ring on a super-zoom, i.e. the Sony R1 had it, as did a couple of others. It's just an expense that manufacturers could no longer afford in their race to the bottom in terms of prices for P&S cameras. It's a shame that Sony decided not to continue the R1 product line, you'd think there'd have been a market for a premium super-zoom with an APS-C sensor and a mechanical zoom, but the decline in SLR prices hurt it. There's now no super-zoom on the market that can give you anything close to the low noise levels, depth of field, and high-ISO performance anything remotely close to that of a D-SLR (forget about fast AF focusing, that's just not going to happen with contrast-detection). It's like none of the major players want to produce a high-end super-zoom for fear of hurting their D-SLR sales, instead you see stuff like 4:3, Micro 4:3, and NEX, systems that will likely join film formats like APS, Disc, 126, and 110. Some day I'd like to see a review of a Panasonic camera that didn't have a statement about how the images are "good enough" despite the noise. I.e. the Imaging Resource review of the FZ28 states, "Though there is an ongoing problem with sensor noise at even the lowest ISOs, optical quality and overall image quality are good enough that most buyers ignore it and persist in blissful satisfaction with their faithful little image makers." Every other review of this product line, including the newer FZ35, prominently notes the noise issue.
