Originally posted by noelpolar Spent last week at Gluepot (a Mallee bush bird reserve in South Australia).... a bit quiet (bird wise) there at the moment... anyway did some longish walks so just took the F*300/4.5 on my K3III.... the lazy kit (as opposed to the 150-450).
Not having the 150-450, I can’t remark on its physical characteristics, but I do have the Sigma 150-500 so I wouldn’t call the F*300 a lazy kit, more like an agile kit or a back-saver kit (but it is a great combination with the K-3iii).
Come to that, the merits of both kits are well-displayed in these photos. Not to mention the photographer’s.
