I took a 270MM lens and put on my 2x lens thing to make it 530mm. I have bought the lens for $25 at a pawn shop a few months ago. I noted as I went back to some of the pawnshops they stop takeing cameras. or they sold the all I do not know. Some do not carry cameras now. anyway I just wanted to see if it makes a diff in zooming in with the big len I have. I like to get a 500mm or even that 800mm lens I saw on the net but it cost too much. I also have a 90mm lens no zoom on that. I took some shots with that too to see what happens. I post some later. I had to delete about halve the images and will delete more on the day I used this lens. I need more lighting with it for the 2x takes two f stops down as is and I know the big lens needs more light than my smaller lens too. I was happy with what I saw. I know it will work on close ups with out getting in they face. Do not want that . lol thanks for looking and comments. I thinking of putting this in the music book I putting together. Plus I was wondering if I should adds captions to the images like I do here on RR? My son say "no"; just let the image spoke for it self.
