Autofocus zoom starting at 28mm are widely available on the after market and very often cheap (because widely available!). But you will certainly realise that with APS-C sensors, 28mm is too long. There is a big difference between 24mm and 28mm. 24mm is realy usable indoor and also good for landscape. Unfortunately 24mm was a rare focal lenght in the fim era. So zoom or prime lenses covering 24mm are expensive on the after market compared to their 28mm brothers. Have a look to this cute discontinued Sigma 24 Super Wide II f/2.8
