yep, I know, another one.
still looking at changing the quantity of glass in my big bag, and am thinking about another option
I have and don't use the Sigma 18-50dc, Sigma 28-300dg, (twice repaired, once for a broken zoom lock and once for gear stripping and makes rough noise when focusing).
Also, was looking at replacing my Tamron 70-300 ld di for a newer version.
I would like some thing that gets close to 500mm, have looked at reviews for the Sigma 50-500 and 150-500, and am now thinking about the 120-400, is this good enough to use for cropping pictures taken at at airshows and for wildlife photography.
I could be persuaded to let my Sigma 400mm f5.6 non apo/macro prime go too, have seen them for sale around the £150 mark and more on ebay.
but what do you all think?
thanks in advance
