[QUOTE="RocketCowboy, post: 533280, member: 25095"] Nope, even though the Sigma is designed for a crop sensor APS-C body, the focal length is still the focal length and does not identify the change in field of view. That 30mm Sigma will have an effective focal length of 45mmc where the 24mm Samyangs will be closer to 36mm as you mentioned. Sent from my iPhone using Tapatalk [/QUOTE]
