The Digital SLR or DSLR lets you change your lens, making it a versatile option for those that also want an optical viewfinder. Some of the things to look for on more advanced Digital SLRs is a top LCD screen, which you will find on some models, making it easier to see what the camera settings are. Many of the latest DSLRs also feature built in Wi-Fi making it easy to transfer photos to your smartphone or tablet.
