Duplicate Clubman telephoto — the non-macro 80-200mm for Pentax K, same as ID 4529.
The Clubman 80-200mm f/4.5-5.6 for Pentax K is essentially the same budget telephoto as ID 4529 with slightly different aperture specification — f/4.5-5.6 versus f/4.5-5.5. The difference is negligible. Same Clubman budget quality in Pentax K mount. Benefits from Pentax body SR. Not recommended for deliberate purchase.
Same basic quality as other Clubman 80-200mm listings. Sharpness acceptable stopped down. Variable aperture. Standard telephoto range. Build quality basic. The marginal aperture specification difference from ID 4529 is meaningless in practice. Pentax body SR is the only practical benefit.
Pentax K mount. Manual focus. Same practical characteristics as IDs 4529 and 4530. The macro version (ID 4530) is preferred if choosing between Clubman options. Build quality basic. Better K-mount alternatives readily available.
Essentially same as ID 4529. Do not purchase multiple Clubman variants. The macro version is marginally preferred. Not recommended. Better K-mount telephotos at similar prices.
