Hello. I will be aquiring a new PentaxK100D with the 18-50MM lens in about 8 weeks. This is my first camera. I bought my girlfriend a Canon Ixus500 a few years ago for her birthday and have been using that over the past few years and thought that it was time to step up. I really enjoy landscape photography. So here are my questions. Do you think this is a good camera to learn on? What sort of batteries are the best in this type of camera? Will i have enough on my hands initally with the 1 lens for it to make more sense to wait before I buy a second lens? What would be the best memory card to get? Are there any good instructional books readily available? I would appreciate any help that you can offer. Thanks.
