I have a rather keen interest in wildlife photography and have had several bridge cameras previously and now have progressed to a Pentax K5. I currently have the following lens

Sigma Dc10-20mm f4-5.6

Pentax Da*16-50 f2.8

Pentax Da18-55mm f3.5-5.6 WR

Pentax Da18-250mm

Pentax A 50mm f1.7

Pentax Da 50-200mm f4-5.6 WR

Pentax Fa 80-320mm f4.5-5.6

Tamron Di 90mm f2.8 macro

Sigma Apo 400mm f5.6

Sigma 170-500mm

Pentax M 300mm f4

Pentax 1.7x AF Adapter

Pentax A 2x-s

Pentax D-BG4

I would really like to invest in a Sigma 50-500mm or similar, but waiting for a rather cheap one on ebay or the likes or an equivalent lens for a bargain price. As above, i have recently acquired a Sigma 170-500.

I am currently studying a level 3 photography course @ Macclesfield College and also a part time foundation degree in Countryside, Conservation, and Recreational Management @ Rease Heath, with the idea of getting a job as a reserve warden or ranger in the near future.
