What is the difference between entry-level and intermediate SLR image quality? Is there a big difference?

The biggest difference between mid-range SLR and full-range camera is the size of optical sensor COMS, which is 36*24mm for full-range camera and 24* 16mm for mid-range.

Otherwise, the shutter speed and viewfinder are pentaprism, and ISO and continuous shooting speed are similar.

In addition, full-frame machines are all metal bodies, most mid-range machines are plastic bodies, and a few mid-range machines also have all-metal bodies.

The biggest difference between the mid-range machine and the entry machine is that the entry machine uses a cheap pentaprism, while the mid-range machine uses a pentaprism. The shutter speed is different, the continuous shooting speed is different, and the ISO is different. The entry machine is made of all plastic materials, without shoulder screen and front and rear dial wheels. The image processor of the mid-range machine is relatively strong, and the image processor of the entry machine is generally poor.

At present, most of the latest entry machines use higher pixels, but the pixel height only represents high image resolution, not image quality.

The image quality is mainly determined by the image processor, followed by the quality of the lens, but usually the image processor of the fuselage is more important.

The simplest example is that the two entry-level machines D3200 and D5200 have 24 million pixels, and the high-end Canon full-frame machine 5D3 has only 23.4 million pixels, but the picture quality of 5D3 is dozens and hundreds times higher than that of D5200 and D5200.

The gradient of machine configuration between Canon and Nikon is very obvious, and the configuration of different grades of SLR is very different.

Pentax's sub-configuration gradient is very small. Both K30 and K50 are mid-range configurations, but the price is entry-level.

Therefore, Pentax K30 configuration can kill all the strongest entry machine configurations of Canon and Nikon.

Pentax's mid-range flagship machine is all made of metal, with super image processor, and the K5 image quality is comparable to that of Canon's full-frame machine 5D2.

Except that the size of the photosensitive element is a frame cutter, the configuration in other aspects is equivalent to that of Canon Nikon full-frame machine.

Therefore, Pentax K30 or K50 is the strongest configuration entry machine, and Pentax K52S is the strongest non-full width machine. The price is relatively affordable.
