Looking for a wide lens and the above looks great value, but I am concerned its an old lens and may not be up to the 45mp sensor.

This Notice provides guidance to member firms regarding their obligations under FINRA Rule 3310 in light of the adoption of FinCEN's CDD Rule. In addition, the Notice summarizes the CDD Rule's impact on member firms, including the addition of the new fifth pillar required for member firms' AML programs. Member firms should also consult the CDD Rule as well as FinCEN's related FAQs, 8 which FinCEN indicates it will periodically update. Then he took his staff in his hand, chose five smooth stones from the stream, put them in the pouch of his shepherd’s bag and, with his sling in his hand, approached the Philistine.As I'd normally expect for an ultra-wide lens, distortion at 17mm is quite pronounced. Here Imatest recorded 7.46% barrel distortion, which is quite high, but not uncharacteristic for a lens of this type. Unfortunately the curvature increases towards the corners in a non-uniform fashion, which may make it difficult to completely correct the effect in image editing software afterwards. At 40mm very mild pincushion distortion is present. Here Imatest recorded a level of 0.303%, which will be barely noticeable in most cases. The same lenses are show fully extended below (the 17-40 L does not extend - it remains the same length at all focal lengths). On July 19, 2016, FinCEN published Frequently Asked Questions on the CDD Rule. See U.S. Department of the Treasury Financial Crimes Enforcement Network Guidance FIN-2016-G003, Frequently Asked Questions Regarding Customer Due Diligence Requirements for Financial Institutions (July 19, 2016) (FinCEN FAQs). Who is the Canon 17-40mm f/4L for? Arguably everyone shooting with a DSLR today has use for a focal range like this.

Muhammad Sarwar: (Pagans) has your Lord given you preference over Himself by granting you sons and taking the angels as His own daughters? What you say is a monstrous utterance. In brief - If you are going to shoot primarily with narrow apertures or your budget is restricted, the decision is easy - get the Canon EF 17-40mm f/4L USM Lens. Were you a slave when you were called? Don’t let it trouble you—although if you can gain your freedom, do so. 22 For the one who was a slave when called to faith in the Lord is the Lord’s freed person; ( F) similarly, the one who was free when called is Christ’s slave. ( G) 23 You were bought at a price; ( H) do not become slaves of human beings. 24 Brothers and sisters, each person, as responsible to God, should remain in the situation they were in when God called them.

This is my favorite ultra-wide lens because, on my Canon 5D full-frame, it's sharper than my Nikon 12-24mm on my D200 and sharper than the Canon 10-22mm on a Rebel XTi. The scale on the left side is an indication of actual image resolution. The taller the column, the better the lens performance. Simple. And he took his staff in his hand, and he chose for himself five smooth stones out of the brook, and put them in the shepherd's scrip which he had for his store, and his sling was in his hand; and he approached the Philistine. then the 16-35 L II is a better choice (you need at least f/2.8 - or image stabilization for motionless subjects).

Distortion ranges from moderately strong barrel distortion at 17mm to mild pincushion at 40mm with 24mm being the approximate point of minimal distortion. It should be noted that this is an older lens that was released in the days before digital cameras and it covers the full 35mm format, making it suitable for use with full-frame Canon DSLRs. This being the case, the resolution figures obtained using an APS-C body (EOS 40D) are encouraging as they are better than those obtained by dedicated EF-S lenses. Being critical, wide-open performance at the shortest focal length is slightly below the performance at other settings but the deficit is only slight. No visible edge distortion could be detected. There's more to resolving power when it comes to IQ.. I'd bet that 17-40 produces a better image than the 15-45 or the 18-150,
