with a limited budget, of legacy which lens would be best for use on the pentax K1, WR doesn't matter, sharpness is essential throughout the frame as well as across the range, always use lens hood, very often use rated aperture, speed and focus accuracy, lens resolution is also important because of the frame cut, 4 lenses are included in the short circle:
1.Toxina ATXPROSV 28-70 / 2.8
2.Tamron 28-75mm F2.8 AF XR Di LD Macro SP
3.Sigma 24-70mm F2.8 EX DG Macro
4.Pentax-D FA 28-105mm F3.5-5.6 ED DC WR
has anyone experience in parallel with at least two lenses of the above
