Lens Review
Introduction | Pentax HD DA 21mm F3.2 AL Limited lens performance | Pentax HD DA 21mm F3.2 AL Limited versus Pentax smc DA 21mm F3.2 AL Limited | Conclusion

With lens compactness being a real selling point these days the popularity of Pentax’s tiny ‘pancake’ primes continues unabated. The smc 21mm f3.2 AL Limited was a well-liked model and the new HD version, with its improved coatings, has brought subtle but welcome enhancements to image quality. If you already own the smc version there seems little real reason to upgrade, but if you were thinking of picking one up for the first time, the small premium of around $50 appears to be a small price to pay for the benefits.
