The various camera images below are of some of the digital cameras I have owned and used, it all started with the Olympus Camedia C100 (See Below) which ate batteries at an alarming rate but produced some colourful images considering it "only" had a 1.3 MP CCD digital sensor, the current CMOS sensors don't have the same effect and I don't know why. Most of the digital cameras I have purchased are used, and I have only experienced a problem once or twice in over 25 years or more of buying online. The only cameras I have purchased new were the Minolta DImage Z1, the FinePix S3380, and the Nikon Coolpix P600. When I first used the Z1 it was amazing, the 10x zoom and the clarity of the resulting CCD images were overwhelming at the time for me, and that feeling has never been felt again until I picked up the Olympus OM-D E-M5 for the first time a few years ago.
I still have the OLYMPUS Camedia C100 (Shown below), and now my great-grandson uses it when we go out and about taking photographs. The Nikon Coolpix P600 Bridge is still in my possession but has now been relegated to its own camera bag, it used to be in my backpack along with all my other camera gear that I was going to be using that particular day and will now only occasionally take it with me for those "just in case" moments, I now prefer to carry the EM-5 II with a manual lens, usually the Tamron 28mm f2.5 and my E-M1 II with the Lumix 14-140mm zoom attached, or if the weather doesn't look good the OLympus 14-150mm zoom, along with a few more lenses of choice in the backpack. If I happen to be using my bike the gear ends up in the panier bags which allows me more choice of goodies to use.
The Olympus "OM-D E-M1 II" has far surpassed everything I could have thought a modern camera should be capable of, I hear online experts say it "Only Has A 20 MP Sensor", well, 1.3 MP was good enough all those years ago and I can still show off those Images I captured without anyone questioning what resolution the sensor was. Time brings experience which in turn results in knowledge of what is best, online experts are two a penny but your own experience is all that counts.
