[QUOTE="nidding, post: 292650, member: 17555"] Hmm. By chance I found this thread after discussing this with my dad earlier today. He had found that he had a 'gap' between to zooms that both went to 70mm but from different ends. He thought that it had to do with the FX/DX crop, because one of the lenses were an older lens not minded explicitly for DX. I hold that this could not be the case, as this is often refuted right here on the forum :) Now that I have come home, I have tried a few lenses myself, all 55mm 18-55, DX [url=https://flic.kr/p/n4Xmxw][img]https://farm4.staticflickr.com/3735/13828241884_1405308fcc.jpg[/img][/url][url=https://flic.kr/p/n4Xmxw]18-55 @ 55[/url] by [url=https://www.flickr.com/people/85695022@N03/]jonas_sandager[/url], on Flickr 55-200, DX (sorry for the bad focus, the cup was just a bit closer that closest focus distance) [url=https://flic.kr/p/n4Xm3U][img]https://farm3.staticflickr.com/2818/13828240224_ca4e865d89.jpg[/img][/url][url=https://flic.kr/p/n4Xm3U]55-200 @ 55[/url] by [url=https://www.flickr.com/people/85695022@N03/]jonas_sandager[/url], on Flickr 55mm macro, FX [url=https://flic.kr/p/n4VE6v][img]https://farm8.staticflickr.com/7271/13827910703_985cc0093a.jpg[/img][/url][url=https://flic.kr/p/n4VE6v]55 macro[/url] by [url=https://www.flickr.com/people/85695022@N03/]jonas_sandager[/url], on Flickr All were at f/5.6 and 1/15 second. My stand is very wobly, so the framing is not exactly the same. But close enough to see the big difference in field of view. As you can see, the 18-55 is much closer to the 55 macro in it's field of view than the 55-200 which clearly outrule the FX/DX explanation. Focus breathing seems like a much likelier candidate. It's dark outside now, but I will try to remember to take some tests at infinity tomorrow. [/QUOTE]
