The Hasselblad H6D-400c MS is widely regarded as one of the best expensive cameras on the market for professional photography. This medium format camera offers extremely high color accuracy and a massive 400 Megapixel output, thanks to its 100 Megapixel CMOS sensor. Although it is a significant investment, many photographers believe that the exceptional image quality and versatility of the H6D-400c MS make it well worth the price.
Another highly-regarded option is the Canon EOS R5, which is the most expensive camera in Canon's current lineup. This full-frame mirrorless camera boasts a 45-megapixel sensor, fast autofocus, and impressive video capabilities, making it a popular choice for both still photographers and videographers. While it is certainly not a budget-friendly option, many photographers believe that the EOS R5's advanced features and excellent image quality make it a worthwhile investment. Ultimately, the best expensive camera for professional photography will depend on your specific needs and preferences, but both the Hasselblad H6D-400c MS and the Canon EOS R5 are highly respected choices in the industry.
