Originally posted by beecherheather I have a Pentax-kx, and I have the 18-55 lens and the 50-200 lens. I am taking photos of families and children, mostly outdoors. I could use ANY help in choosing a new lens, as well as any settings I might need to get the best photo.
Thanks!!
AS others have said, take it slowly. It took me a lot of time and money to face up to the fact that, for me, lightness and compactness are crucial qualities, and for that reason I enjoy shooting with small primes more than with the Sigma 17-70 zoom, excellent though that is. Equally shooting with primes and travelling with other people is hell because you don't have time to switch viewpoint or even change lenses. So in those circumstances, ironically, I often just bung on the original 18-55 (I have a rather good one).
Your best reason for buying a prime lens now would be simply to gain technical experience, and you could not do better than an M50 (1.4 or 1.7, they're both good - disregard the people who say the 1.4 is too soft wide open), or an M28 (2.8 or 3.5). All of these are cheap as chips and would force you to educate yourself about settings and improving your focusing technique. And you would enjoy them as little marvels of engineering, and probably produce some nice photos too.
But I wouldn't spend serious money on another lens until you have decided what your photographic priorities are. Personal experience and a depleted bank account speaking here.
