I need to know which lens will work for Nikon D80?
I'm trying to get a broad view of a landscape, which is best lens Sigma 12-24mm F4.5-5.6 Asperical or Sigma EX DG 15-30mm F3.5-4.5 EX DG Asperical. Also, I have a macro lens is Sigma 70mm f2.8 EX DG MACRO suitable or fit my camera? Finally, I need a telephoto zoom, which is better SIGMA APO 70-300mm F4-5.6 DG MACRO or SIGMA 70-300mm F4-5.6 DG Macro? In general, I need 3 additional lenses, one for WIDE ZOOM (landscapes) the second for MACRO (insects and flowers) and one for telephoto (zoom). At this point, I have a Nikon 18-135mm1 :3.5-5 .6 G ED. I need stronger glasses. free to suggest anything you feel you can be better or more efficient Feel what I'm looking for. I am looking to pay no more than $ 600 per lens. I would like the price to be about $ 500. Thanks
Sigma 12-24mm F4.5-5.6 for landscapes The SIGMA 70-300mm lenses are the same except for apo coating to reduce chromatic aberrations (Colors on the edges of things such as windows or buildings which are supposed to be there) … but I would suggest that the AF-S 70-300mm f/4.5-5.6G ED VR Nikon "If in Sigma macro to … flowers 70 mm is well … to insects … a longer focal length as 150 or 180 will allow more space between you and the insect … 70mm if you want to get closer, get something like the Sigma AF 150mm f/2.8 macro if you prefer to be further away it seems like a great … investment is buying lenses to cover every possible thing you might want to shoot or know for sure is we want to photograph things regularly? if you have something in mind that you want to photograph, getting 2 instead of 3 lenses that are of better quality can get to use if its what you really want to shoot.
