Why am I writing this? Well, it because of the "newer is better" syndrome. Upgrade, upgrade, upgrade! Yet, I find that several older and "obsolete" models provide excellent images.
For example, the S90 or S95, the G11, G12, and G15, the ELPH 330HS, the SX230HS, the SD950IS, and a host of others. Picking one of the good ones from the past gets one into very good image quality for a fraction of the cost of a new model.
For example, I just picked up a very nice used Canon S90. I'd had one in the past, and liked it a lot; but at some point, I decided to "upgrade" to the S95. Pretty much, I found I had gone sideways, and in the process lost something. Ergonomics were better controls worked a little better, the size and weight were virtually the same, and my Franiec grip fit the S95 perfectly. Yet, the S90 returns a little better looking JPEG image if you set the internal settings to best advantage. A small difference; but visible. Those two models are from 2009 & 2010; but I'm hard pressed to find anything better in the same size and weight range that goes to at least 100 mm.
Other cameras that stood out for me are the SD950IS, G15, SX230HS, S3IS/S5IS, and the ELPH 330HS. Other really good cameras from the past (at least 4 years since introduction) are the Panasonic FZ150 & FZ200, Canon's SX50HS, the Panasonic LX5 & LX7, the Olympus XZ2, and the Fuji X10 & X20. I'm sure there are more that I haven't experienced.
We're being sold a bunch of cameras with 1" sensors which are larger, heavier, and a lot more expensive. Yes, the best of them are better at ISO 1600; but how often do we need that? The S90 in JPEG makes really good borderless 8.5" x 11" prints with some cropping at ISO 800 - do I really need more?
Somehow, I managed to get along in the 70's, 80's and 90's with ISO 100, 200, & 400 print film with an occasional roll of ISO 800. Today; we seem to feel we have to have a tack sharp, noise free ISO 1600.
Sorry for the long rant. I have several newer models (an FZ1000 at the top); but I'm finding that selected older ones give me some excellent images, and newer models are compromised by market "demands".
