Originally posted by Dan Neeton I am really torn between Pentax k-70 and Canon 200D as the canon kit lenses are really good. (Can get Canon 200D with 18-55mm and full frame 50mm prime for £519)
The cheap Canon combination would be false economy. The K-70 is a much much better camera and can serve you well as your skills and experience develop.
The response by @Mikesbike nails it. I'd just underline a couple of his points because the significance of them might not be obvious to someone new to DSLRs.
When you read a lot of camera reviews, you go crosseyed after a while with all the features referred to. In day-to-day use, for the long haul, a lot of them don't matter much or at all. If you ask most of us who have used a DSLR for a while, they will tell you what is important in everyday use. A big bright viewfinder really matters. So does ready access to the controls for shutter speed, aperture and ISO. The Pentax system of bright full viewfinders and dual control wheels (three on high end models) is just wonderful. These are features cleverly designed by engineers who understand photography, not something driven by marketers or bean-counters. (With all due respect to marketers or bean counters.) By default you control the shutter speed with the dial placed for your right index finger and the aperture by the dial placed for your right thumb. It works beautifully.
Pentax has two unique modes that let you take maximum advantage of this. One is HyperProgram that @Mikesbike mentioned. Every camera on the market has a P (Program) function. But with Pentax you can just override the default settings. So, for example, if you are in P mode and the camera says the correct exposure is 1/125th second, f5.6 ISO 400, you can just override one or two of those settings and the camera will respond. Want a faster shutter? Turn the front dial so that it reads 1/250th and the camera will adjust the aperture and/or ISO. Want a shallower depth of field? Turn the rear dial to f4 and the camera will adjust the other settings.
The other unique mode is TAv. That means you set the shutter speed and aperture and the camera sets the ISO, within a band you specify. It's kind of semi-manual. It's probably the mode I use the most - particularly for wildlife, with a zoom lens, where you are constantly trading off between the variables.
WR is a big plus too - dare I say it? - especially if you live in the UK.
As for the lenses, the 18-50 is effectively £100 if you buy it bundled with the camera at Jessops. But I'd still say the DA 18-135 at effectively £260 is a much better buy. It will do everything the 18-50 can do (except fold up very small) but a lot more besides. I'd suggest using the 18-135 for some time before working out what your next lens purchase should be. (If you want a 50mm prime without spending a lot, there's a wealth of choice in Pentax.) With the 18-50, you'd be very soon looking for a longer/faster lens, and once you got that lens you probably wouldn't use the 18-50 much.
Here are some shots to illustrate how versatile and capable the 18-135 is.
