Vivirtar 500mm Mirror Lens
Greeting from the USA here in PA.
A number of weeks ago, I had purchased a Vivitar 500mm Mirror Lens that came with a 2x Teleconveter and 3 different Filters. Since I have never used a Mirror Lens such as this I had really no idea on just how well this would be with my Pentax K100D DSLR.
I have been taking this Lens out on, what I call, a "learning process" to get to know how this Lens will work. Since you can not change to AV Setting and always is a fixed apature setting of f/4. I've been having some trouble with this Lens and can't seem to get the settings right or even know where I should start. Everything that I seem to try just does not work out well.
I've been reading that this 500mm Lens does good Images, but just how to get them that way is what I have a big problem with. I don't want to get rid of it, because I know that this Lens will do well.
If you have any suggestions on just how to use this kind of Lens, I would be more than grateful. Thanks for your help in advance.
