There's nothing interesting in that gap on a crop.
Yeah - I am pretty much there too. I have them on a 40D, and quite honestly, the 11mm difference I can sneaker zoom to compensate as I likely wouldn't be at 28 inside anyway unless I was shooting detail.
Not looking to specialize on RE, just want to learn it. It is a great general purpose kit.
And if I do fall hard into it, I can always use the MikeKelly or TGrundvig business model (well without the home inspector background and floor plans - lol)
