They say that some "hotspot" appears when you shot it with incompatible lenses. Is that ture? Better IR filter would work with these lenses or not? Which one should I buy?

That doesn't make any sense to me, as far as I'm aware any filter will be 'compatible' with any lens provided you buy the right filter thread size. The canon 18-55 has a 58mm filter thread.

Note that the IR filters you buy like that are not really that good - they block any light that is not IR, but your camera has a built in 'low-pass' filter that block only IR light, meaning that you need ultra long exposures in order to let enough IR light through the lens filter so that enough of it can still get through the internal low-pass filter. These filters still work, but just be aware that you're going to typically need 30sec - 2 minute exposures for a landscape type shot. Obviously, portraits are out of the question.

I found that information for 58mm filter that costs $10. Seller describes it as incompatible with some lenses due to "hotspots" that appear on photos. They say that it's due to lens' structure and it cannot be corrected in camera.

I bet it's due to poor filter and poor manufacturer (Massa company). Am I right? Which IR filter would you buy to avoid that? I'm going to use it for 50mm f/1.8 II lens as well as kit lens.
