I want to buy a camera, but I don’t know which one is better, Pentax k30 or Canon 600d.

Compared with 600D and K30, Pentax K30 is better.

Comparing all the current entry-level digital SLR cameras, overall the best is the Pentax K30. The individual technical indicators of some cameras are indeed higher than the K30, but in comparison with overall performance, the best entry-level camera currently (and there will definitely be ones that surpass the K30 in the future) is the K30.

The K30 is not only better than all other entry-level machines, it is even better than the Nikon D90 and Canon 60D, two of the best-selling mid-range machines in the past.

The lack of after-sales service is indeed a flaw of Pentax. However, the high quality of Pentax products ensures the extremely low failure rate of Pentax products.

Pentax lenses are indeed not as rich as Nikon and Canon lenses, but the lenses you need are all there - enough for you. Don’t you think about it: How many lenses can you buy in your lifetime? Nikon and Canon lenses are abundant, but can you buy them all? Do you need to buy so many lenses?

As for the Pentax machine you said is small and not suitable for you, there is nothing we can do about it - we cannot increase the size of the K30.

But I think you should pay more attention to the overall performance and cost-effectiveness of the camera, right?
