The Olympus e-410 digital single lens reflex camera (or DSLR) is the oldest camera in my suggested used list.

Introduced in 2007, it was one of the smallest and lightest true optical DSLR cameras ever made. A traditional DSLR camera is where you looked through an optical viewfinder to see what was coming into the lens. It has a 10 megapixel Kodak sensor and a new lens mount that was part of what was called the four thirds system.

The camera it could also be switched to an early mirrorless system where you pressed a button and what you saw on back the screen would show what the picture would look like when taken. It was a bit clumsy, but especially useful in tricky lighting where you could dial in lighter or darker and see the image change. 

Also this was a still photo camera only, as in no video use. 

It was a time of transition and Olympus and others soon switched over to an all mirrorless system with no mirror or prism in favor of an electronic viewfinder. Olympus made even smaller cameras and lenses using a smaller lens mount.

Today the e-410 is a little bit of "an orphan camera."The two most common lenses include a wide angle to modest telephoto and then a companion lens from mild tele to longer tele. Other lenses for this unique are fairly rare.

The camera is frequently sold with both lenses which is all most casual photographers will need.

In 2007 at that time 10 megapixels was considered a good standard size while today many are 12, 16, 20 or more. But again, for most people 10 is more than adequate resolution for a decent print and certainly adequate for any online photos you are posting. 

Unlike bridge cameras, the e-410 has a full complement of a shutter speeds and apertures as well as several automatic functions and even a unique electronic dust removal system so any dust getting into the camera body while you change lenses will not settle on the sensor. It still remains a comfortable and easy to use camera, perfect for learning photography and what exposure is all about.

It stores images onto a somewhat older compact flash cards which are still available and also a second slot for a now discontinued card called an XD. External card readers that accept compact flash cards are quite common but fewer except the XD card. so the best way to go is to use the compact flash card. Aftermarket batteries and chargers are still available. At the time of this writing I am seeing a slight increase in the selling price of the camera with one lens up from $50 to more than $70 and a complete outfit with two lenses and accessories sometimes topping $100.

For enthusiast photographers who grew up on film SLR cameras it is a great way to get back into the hobby without spending a great deal of money, especially if you get the camera with both lenses.

There is something that feels good about a system that feels like cameras you grew up with!
