Re: Tamron 28-200mm f2.8-5.6 Di III RXD - infrared hotspots?

Thanks Niels

Really helpful - looks like a great option to replace the 24-70 f4 I’m using now which is very average.

I’vefound wide options to be limited - 16-35 f4 is ok most of the time - haven’t been able to find out how 16-35 f2.8 works for IR but that would be a possible candidate.

My ultra-wide solution is a Canon 17tse with a metabones adapter - clean throughout f stop range, very sharp across the frame and with the option for using shift to get to about 12mm equivalent. Heavy old lump to carry round though!
