6D + 24-70 f4 IS.
Shot on the Sussex coast at Adlebrough. A three frame stitch hand held, ISO 320.
Nice image. I haven't seen much from the 24-70 f/4. How do you like it?
Many thanks Click, Edward and Dustin.
The only thing that makes the 24-70 IS difficult to assess is the cheaper price and even cheaper availability of the 24-105. The 24-70 IS is the better lens, especially mid frame and in the corners; it is really prime quality most of the way, whereas when you take the average of the 24-105 across the frame it lags behind the primes. The lens is very compact, in practice significantly shorter than the 24-105, and the manual focus quality is a little better. The IS is meant to be more effective but I haven't enough evidence to come to a decision yet.
Reviewers of the lens have stated it is not as good at 50mm. We haven't found this.
In summary I would say if you want prime quality in a zoom but also need IS get the 24-70 f4L IS.
Here's a picture of the pool at Flatford Mill and 'Willie Lott's cottage made famous throughout the world by the most famous of English landscape artists John Constable with his "The Haywain" oil painting finished in 1821. Now owned by The National Trust the area has been preserved pretty well since then, but the pool is deeper now because the Eastern part of England has sunk one foot lower over the last two hundred years !
Shot with the 6D and 24-70 f4L IS @ 50mm. I'll put an example of this lens at 50mm @ 100% in the 24-70 IS image gallery.
