Been looking at my photos over the last few months and I'm starting to feel want a few more lens options, namely a long reach tele and a low light wide. My current gear is in my sig, but I'm considering buying the Canon 28mm f1.8 and the 400mm f5.6, perhaps with a 1.4x extender at a later stage. I'm not ready to buy yet, the wide is probably priority in the next few months, the 400mm later in the year, maybe next, but both lens have mixed reviews, both good and bad, but im mindful that a replacement 400mm would probably have IS and be priced above my comfort level.
Whats the feelings on here, anyone own either, good/bad experiences... Is the Sigma 30mm better, would a 300mm f4 IS with a 1.4x be better ? I just don't think that a 17-55mm f2.8 will cut it in the low light I'm taking photos in and struggling to justify £2k extra on a 5DII/III, plus the 400mm I want in the longer term.
I'm Still considering a longer term replacement for the 70-300mm non L, but that's a few years off, I'm generally happy with that apart from the AF and long end, so a 70-200mm F4 or 70-300mm L are looking like good contenders a few years down the line, with a replacement camera at that time too.
