Is Nikon D90 comparable to Pentax K5? Which is better? Which is more cost-effective and more suitable to start with? (regardless of the lens group. Want to shoot the scenery. Lightweight)

There is no comparability, and the positioning of K5 is much higher than that of D90.

The price of K5 is still relatively high, so you can almost buy two D90s.

D90 is very popular, with excellent hand feel and lighter weight than K5.

K5 is the flagship machine of P family, with outstanding functions and excellent picture quality. It is a good machine, with high price and small population.

Therefore, it is suggested that if the budget is sufficient (above 12000), you can choose K5; Choose D90 for the budget of 8000-9000.

The reason why the reference price is so high is because the landlord wants to take pictures of the scenery. I recommend a wide-angle zoom lens to help you see some: for example, Pentax DA16-45 mm F4 ED more than 2000; Sigma10-20mm f 4.0-5.6 ex DC HSM 3500 or so; Nikon af-sdx16-85mm f3.5-5.6g edvr4500 or so.

If the budget is not high, you can also choose D90 sets (18- 105VR), which is enough to get involved in photography, and the price is around 7000.
