Hi everyone I've been using my A77 for a couple of months now and I'm very happy with the results, It was for me the best option at the time because I wanted a camera that would be an investment but still affordable and good enough to allow me to improve my learning curve without having to change it in a short period of time. I have been doing everything with it but I do want to specialize and dedicate my work to Real Estate Photography and I know I need a wide lens to shoot those pictures. I went to the local dealer and they have a Sony Wide Angle lens but it's too expensive, I have been reading and trying to figure out what other wide angle lenses I could use for the A77. I will be in LA, next month so I want to buy it there too because here the prices of every single peace of equipment are twice as expensive. Any advice on the more appropriate lens I can use? So far the options I found are: [h=1]Sony DT 11-18mm f/4.5-5.6 Aspherical ED Super Wide Angle Zoom Lens for Sony Alpha Digital SLR Camera[/h] [h=1]Sony SAL-20F28 20mm f/2.8 Wide Angle Lens for Sony Alpha Digital SLR Camera[/h] [h=1]Sigma 10-20mm f/3.5 EX DC HSM ELD SLD Aspherical Super Wide Angle Lens for Sony Digital SLR Cameras[/h] [h=1]Sigma 10-20mm f/4-5.6 EX DC HSM Lens[/h] Thanks for your help!!
