Originally posted by nerky774 I have three lenses from the film era. I have a SMC- Pentax-FA 28-90mm, a tamron LD telemacro 70-300 AF, SMC pentax 1:2 50 mm. I am planning to add more in the future.
By now you know the K-1 is absolutely worth it.
But it will only be as good as the glass you put in front of it. This glass you have now, is not so good, so you won't really be getting the best benefit of owning a K-1.
So my recommendation comes with an "if".
IF you can spare at least another 500 dollars after you get the K-1, then get the K-1. A good 500 dollar starting set of lenses for it would be the DFA 28-105mm f/3.5-5.6 (it's a kid lens but a really good kit lens) plus a used SMC-F 50mm f/1.7 lens (there's one in the market place for 95 dollars right now, which is about right about what you'd pay for one).
If you can't buy the lenses - then use the money to buy some good FF lenses first, use them in the K-70 until you buy the K-1. The two lenses mentioned earlier will still work great on the K-70, albeit using a smaller portion of the image circle. Other suggestions will depend on whether you like manual focus, autofocus, and what your interest subjects will be.
