Crop sensors better than full frame for macro photography?

[ecka]

When I was using 7D for macro (mostly hand held) it was very difficult to get the right framing and the subject in perfect focus at the same time. Now, with 6D I don't worry about the framing so much (or at all), because FF is much more crop-friendly, so I can focus on timing and DoF positioning.
Another FF advantage is MP-E 65/2.8 1-5x Macro, which is somewhat limited by it's lowest magnification of 1:1 macro and not every insect is small enough to fit inside APSC framing without cropping something off (long legs, whiskers, etc). You can always crop, so FF gives more flexibility.
TBH, when talking about size, I think that crop sensor has no advantages other than price.

Agreed. Not that you can't make excellent images with a crop sensor, but lower cost is its real advantage.

I was hesitant to make a comment here, but things seem to have calmed down a little.

I do a lot of Macro, albeit it's all Underwater Imaging, I have two set ups for Underwater.

1DMK IV in a Seacam Housing, I find the APS-H format just get's me closer and for my Macro Imaging works better than anything else I've tried (FF/APS-C), primarily it allows me to better utilise the 100f/2.8 Macro L IS.

For everything else I use the 5DMK III again in a Seacam Housing, FF seems to the wide angle Imaging better than the 1.3 Crop of the APS-H format.

For me - shooting underwater macro - I am very happy with my 7d + 100L - (granted the 1d series + housing is a little out of my price range)

The reason I like aps-c is because of the greater working distance (not always necessary) but there are some shots I am sure I couldn't get on full frame underwater (and there is no port for the 180L on my ikelite setup).

I do plan to put together a FF rig sometime soon, but I will keep my 7d mainly for underwater macro.

Just my opinion in regards to my shooting.
