vs Competition
The competitive landscape has shifted meaningfully. The Fujifilm X-H2S now challenges with a stacked sensor and 40 fps bursts at a lower price, making it the action shooter's alternative. The Sony a7R V brings 61 megapixels and a far more polished autofocus system, though you pay for it. The OM System OM-1 is the wildcard: smaller sensor but incredible stabilization and computational tricks that let you leave the tripod at home. And the Nikon Z8 essentially packs a Z9 into a smaller body for roughly the same money as the higher end of this camera's range, with video specs that embarrass most stills focused bodies. Against all four, this camera still wins on lens availability and color straight out of camera, but it no longer dominates any single category the way it once did.

Price
Value & Pricing
At $1300 to $4200 depending on body and kit configuration, this camera sits in a fiercely competitive bracket. The entry point remains accessible for enthusiasts moving up from crop sensors, while the higher end now brushes against the Sony a7R V and Nikon Z8, both of which offer more modern video pipelines and higher resolution sensors. You are still getting a workhorse stills camera with an unmatched lens catalog, but the value proposition tightens considerably when the Fujifilm X-H2S and OM System OM-1 undercut it with faster burst rates and computational features. If your priority is pure image quality and lens selection over cutting edge video or speed, the price holds up. If you need a hybrid that does both, the field has caught up.

Verdict
This remains one of the most satisfying cameras to shoot with, delivering files that need very little work and handling that feels like an extension of your hand. But the market has crowded in. Where it once stood largely alone as the sensible premium choice, it now faces genuine pressure from the Fujifilm X-H2S on speed, the Sony a7R V on resolution, the OM System OM-1 on portability and clever features, and the Nikon Z8 on all around capability. It is still the right call for photographers who value lens selection and color science above spec sheet fireworks. Just know that for the first time in years, you have real alternatives worth cross shopping.
