A 300 APO on 1DsIII


Edit: I was just going through my telephoto gear bag and guess what I found? The Kenko TC that I thought was on the lens when I first posted this thread a few days ago. Oops! I\'ve changed the title and edited this original posting text to be correct. I\'m still impressed.

I received a lightly used 1DsIII yesterday, and I\'ve been putting it through the paces with a variety of lenses, including a Mamiya M645 A 300/2.8 APO.

Here\'s a photo of a Halifax/Dartmouth ferry which was tied up today at the Woodside Terminal. First image is full frame. Second image is 100% crop showing the \"Ocean News\" that somebody was reading on the bridge. Third image is 100% crop of some gear on the right of the bridge top; needs some paint to cover that rust on the bracket. Note that the ferries have fore & aft symmetry, and so I can\'t tell port from starboard, at least not from this photo. There is a slight amount of CA on the bright edge of the white antenna in the last photo. I\'ll bet my socks that it\'s entirely from the TC; the A 300 APO is very clean on its own. Trust me, you don\'t want to prove me wrong. [Ed.: the last two sentences were not changed to remove reference to the TC; I guess I just proved myself wrong - happens all the time - at least the socks are already mine.]

The lens aperture was f/4, t=1/2000 sec, ISO 400. No sharpening. Picture style \'Faithful\' (which may affect RAW conversion, I\'ll check later).

The lens was supported on a monopod, and it was focused through the finder (i.e. no LiveView). This is one of two images I took of the same subject. The first was focused slightly behind the front of the bridge (where I was aiming). One out of two ain\'t bad.

I\'m impressed.

A 300 APO, Kenko 1.4x, 1DsIII


I received a lightly used 1DsIII yesterday, and I\'ve been putting it through the paces with a variety of lenses, including a Mamiya M645 A 300/2.8 APO. I generally keep a Kenko Teleplus Pro 300 DG 1.4x teleconverter stuck on the end of the 300 APO, just because I have one.

Here\'s a photo of a Halifax/Dartmouth ferry which was tied up today at the Woodside Terminal. First image is full frame. Second image is 100% crop showing the \"Ocean News\" that somebody was reading on the bridge. Third image is 100% crop of some gear on the right of the bridge top; needs some paint to cover that rust on the bracket. Note that the ferries have fore & aft symmetry, and so I can\'t tell port from starboard, at least not from this photo. There is a slight amount of CA on the bright edge of the white antenna in the last photo. I\'ll bet my socks that it\'s entirely from the TC; the A 300 APO is very clean on its own. Trust me, you don\'t want to prove me wrong.

The lens aperture ring was set at f/4 (i.e. not counting the extra half-stop down from the TC), t=1/2000 sec, ISO 400. No sharpening. Picture style \'Faithful\' (which may affect RAW conversion, I\'ll check later).

The lens was supported on a monopod, and it was focused through the finder (i.e. no LiveView). This is one of two images I took of the same subject. The first was focused slightly behind the front of the bridge (where I was aiming). One out of two ain\'t bad.
