Title: Not for everyone
Review: This lens is great for cropped sensor cameras but is useless on the full frame 5DMark II based on the out of focus results. Sending back to canon did nothing to resolve this problem. I've spoken to other photographers while taking pictures at Bristkecone Pine Forest and they also had the exact same results as I including attempts to have canon fix this problemOn the 50D camera body I'm extremely pleased with the results.
