- DSLR: Canon and Nikon have a wide range of lenses. Pentax also has many bases covered and the contributions of many third parties only add more options to each system.
- Mirrorless - A range of lenses is still being developed for even more established lines, but many options are covered now. The most recent is for newer systems, such as Canon, Nikon, Panasonic, and Fujifilm's mid-size line, which are still in the works.
If you want the widest possible choice of lenses, a Canon DSLR or Nikon is probably your best option. Each of these lenses offers a wide range of lenses at different prices, as well as excellent third-party support provided by companies like Sigma and Tamron.
While Canon and Nikon have decades to build and refine their lens range, for example the Nikon lens mount hasn't changed since 1959, the first mirrorless camera appeared there only 11 years ago. Mirrorless cameras are certainly gaining traction.
As Olympus and Panasonic use the same Micro Four Thirds lens holder and have established themselves as the longest, the Micro Four Third lens range is the most comprehensive, offering a wide range of optics, ranging from ultra-wide-angle zooms to telephoto lenses. rapid.
The Fujifilm lens system is growing, with beautiful lenses of choice and excellent fast zoom lenses. Even the 18-55mm "kit" lens supplied with most of their cameras is very good. There are still some gaps in the line, but Fujifilm is working tirelessly to offer a complete, high-quality line of lenses.
Sony has beautiful high-end optics designed for its full range of cameras like the Alpha A7 III, while it just released a powerful FE 600mm f / 4 GM OSS prime telephoto lens. Now it offers a relatively healthy selection for your APS-C camera and everything complete.
Canon and Nikon have recently released full-frame mirrorless cameras that work alongside each company's line of DSLRs. At the moment, the optics dedicated to each are limited to a handful of lenses, but many others are promised. Not only that, but Canon and Nikon offer affordable adapters that allow you to use lenses designed for DSLRs (albeit with restrictions in some cases).
The most recent change concerns the introduction of the L-mount alliance, a company that unites Panasonic, Sigma and Leica. All three companies are committed to developing products that can be used alongside those of other manufacturers, which should allow the line to grow rapidly.
