How to choose Canon 6D and 55D for SLR entry?

6D is a Canon mid-range camera, and 55D is an entry-level SLR.

the picture quality is the same level. 6D is a metal skeleton (there is no doubt that the engineering plastic shell is correct), which is stronger than the entry machine 55D.

the weight and volume are bigger. More skin, better feel. The 6D has a double impeller, a rear turntable, more buttons, a shoulder screen, and a customized file, which makes the operation more convenient.

the focusing system 6D has a 9-point full cross and a central double cross, and only one point in the middle of 55D is the cross focus. Cross focus and double cross focus can make you focus more accurately, and also improve the focusing speed when you actually shoot. The 6D flip screen is really practical in view angle and concealment, and the 6D flip screen shaft is reinforced, not as fragile as the entry SLR 6D.

the pentaprism used in p>6D is bigger and brighter than the pentaprism used in 55D when viewed from the viewfinder. 6D also has an electronic level. Continuous shooting's speed and maximum speed are higher, which has certain advantages for snapshot. Well, that's basically all. As for buying an APS-C SLR with a red ring head, it's actually stupid, just to satisfy vanity. The red ring head is a full-width head, and it's generally unpleasant to use it on the focal section of the APS-C fuselage. Canon APS-C lenses are also quite good, such as the 15-85 lens, which is the first-class imaging with absolute red circle, that is, it is not full-width without red circle. There will always be so many people who can't play with the whole picture to sell others to buy the whole lens to match the low-level fuselage.
