Hello.
I bought a Pentax K-30 kit with the 18-135mm WR a few days ago, and it has been great fun.
I also have a Pentax-A 50mm f/1.4 lens and I love it.
But I really miss the autofocus, specially in low light. I used the Pentax-A 50mm f/1.4 recently and missed lots of shots because I thought it was properly focused (throught the viewfinder or LCD screen) but it wasn't (when reviewing photos on the computer).
So, I'm looking for a fast prime lens that I can use. I saw several current Pentax alternatives (35mm f/2.4, 50mm f/1.8 and 40mm f/2.8), and I'm more inclined to the 35mm (price) or the 40mm (quality). However, I don't know if the aperture is open enough for low light situations, or if I'll still miss something more appropriate.
In the past I used Nikon's 35mm f/1.8G and Panasonic Lumix 20mm f/1.7 and I loved those two lens. Do you think I'll feel the same with the 35mm f/2.4, or should I wait a little more until I have enough money for the 40mm f/2.8? Or should I just get a 50mm f/1.8? I think 50mm is a little too close for me, I would prefer a 35 or 40mm, but I can bite the bullet if the aperture difference is significative.
Or do you have any alternatives you'd like to suggest (Pentax or third party)?
Regards.
