Hi
I have a chance to buy only one of these lenses as the wife says only one. I
have not used any of them but do have the pentax 43mm limited and was
looking for something similar in terms of image quality, resolution and
flare control. I would love to here from people in this group who have used
these lenses
Thanks
Wayne
