What are the big-soled telephoto cameras? Which is more cost-effective?

I really collect a lot of such models. ...

The originator of the outsole telephoto machine, Fuji X-S 1;

Using 2/3 "CMOS is much larger than the common11.63". Before 1 inch black card came out, its CMOS size was second only to Canon G1x. The primary optical focal length is 24-624mm, supporting optical zoom 1: 2 super-resolution zoom, the maximum telescope equivalent is 1200mm, and the aperture is F/2.8~F/5.6. This is one of the most serious products made by Fuji, a "telephoto professional". The whole magnesium alloy fuselage, even the hood and lens cover are metal! Fuji claims that its lens can be cut and fitted with bayonets to win the TIPA Award. The price of China Bank has been hovering around 5K. Finally, the sales volume was a fiasco. Because the opponents at this price are all SLR cameras, and the image quality of X-S 1 is really not flattering;

Camera body, camera soul: Sony RX- 10 and its successor RX- 10 Mark II;

The most powerful telephoto camera at present. Inherited Sony's powerful genes in the field of camera shooting, various incredible performance indicators: 1 inch CMOS, 24-200mm F/2.8 full-range constant aperture, 1000 frames/second ultra-high-speed photography, 1/32000 "hybrid shutter, 4K video shooting plus full pixel acquisition ... Although the performance is good, the sales volume is a mystery. After all, the price is nearly 8K, and Sony's own flagship micro-single α7 is sold for less than 7K, killing the rhythm of RX series in minutes. ...

Modern telephoto choice: Canon G3X

Canon produces one-inch CMOS, 24-600mm F/2.8~F/5.6. It looks attractive, but the highest shutter speed of 1/2000 is difficult, which means that butterflies can't flap their wings, let alone hummingbirds and long-billed moths. The aperture is not large enough, and the telephoto end tests the photographer's experience. Shoot birds? Without phase focusing, you can only practice your arm strength. Shoot the moon? Don't think too much without a focal length of 2000 mm.
