Hi Mark Could you please give me a your view on third party lenses in that range 300-500mm, fixed lenses or zooms. Since I can not afford a Pentax one and need something not to heavy, what would you recommend. Others told me about a Tamron SP 300, what about mirror lenses, useful or crap? I see some very cheap Makinon 500mm mirror lenses here, but for their cheap prices, it can not be true, right? ;-)
Wondeful bird shots, I would love to have a lens (and your eyes/skills) like that..... thanks alot in advance Markus >>-----Original Message----- >>From: Mark Cassino [mailto:[EMAIL PROTECTED] >>Sent: Wednesday, May 11, 2005 12:19 AM >>To: [email protected] >>Subject: Re: 500mm Zooms >> >> >>I used to own a Takumar 500 f 4.5.
