Originally posted by ennaihl24 I'm actually planing to buy vintage camera because I want to try Lomography, and instead of buying plastic cameras I decided to look for old modeled cameras. I want to have retro/vintage looking photo shots. What do you think I should get from my list of choice? Thanks
I think someone else has already said the the camera body does not particularly affect the "look" of the images. That is correct. The important factors are lens and film choices.
Pentax lenses in general will not take you very close to the plastic camera/vintage look as the quality is much too high.
There is a vast assortment of crappy M42screwmount lenses available. They are generally very cheap and can be used on any of the variations of the Spotmatic. You can also use them on K mount bodies with an adapter.
In terms of your original list, the Spotmatic F will give you the full vintage mechanical camera experience, while the Program A will be more versatile and give you the option of using K-mount lenses.
If the "vintage" look you are seeking is what you see on the "film shots" thread in this forum, much of that is due to lousy commercial scanning. Most labs don't even charge extra for it!
