Lens for a77

A decent start would be a macro such as the Tamron SP AF 90mm F/2.8 Di LD 1:1 Macro or a Sigma AF 105mm F/2.8 EX DG Macro.  One other alternative would be a Minolta AF 100mm F/2.8 (D) Macro.  These are all great for macro and portrait and all these lenses are true 1:1.  In addition, an external flashgun would be handy, but as the A77 and other SLT models have compatibility issues, I don't know which guns work with the SLT system.  Also, check the lens database on Dyxum for lens compatibility as well, and if in doubt, email the manufacturer to check if any adjustments are required before purchasing.
