Canon 5DS for macro

[chauncey]

I shoot a fair amount of stacked floral stuff in macro using a 180 macro lens...
any thoughts on using a 5DS were I to upgrade? Big images are my goals.

Remember that the 5DS has pretty big file sizes! You can chose to use mRaw which is 28M pixels rather than 50.6M and for macro where depth of field is far more narrower this may well be enough. Ive shot straight single images macros with the 100mm f2.8L and the detail at full resolution or 28M is brilliant.

I am shooting macro and stack with a 5DsR. See here for a post on flower stacking with 5DsR and some considerations:

Additionally, the 180M has noticeable lateral color (blue-yellow fringes at edges), so I prefer using the Zeiss 100 M with zero lateral color unless I really need to bridge the gap.

Appreciate the link Zeidora...quite informative. Will be upgrading during the sales seasons.
I've not noticed the color fringing that you allude to at less than f/11.

Here's a comparison of fringes on flowers with 180 M and Zeiss 100 M

scroll down a bit to see the comparison images. Those images were shot on a 5D2, so on a 5DsR the problems will be MUCH more pronounced.
