I have helped others out who claim that they cannot get a good stitch with the Mrotator and everytime to date we have found the problem. (Never as yet has it been the Mrotator!) That's not to say there won't be a first.
Known issues are as follows:
- Tripod center pole elevated. The center pole should always stay flat to the bottom. They flex and move in rotation.
- Flexing tripod. Tripod not of high enough quality. Bigger camera's sitting way back on a support bracket will be more prone to this.
- Incorrect fitment of the FC-E8 or FC-E9 in the Mrotator. Should be pushed home hard while tightening.
- Failure to level tripod and then level Mrotator (Second) and ONLY for position 1 (Do not re-level for shots 2 or 3 "ever")
- Camera set perfectly level when connected to the FC-E8/9 before tightening the fisheye lens.
I have a couple of Mrotators and I get perfect stitching with both if I set up correctly.
Only the slightest movement (slop) can be detected within the Mrotator. This could (I believe) be overcome in two ways. 1) Added grease to shaft to fill minute gaps 2) Redesign the shaft to body using high quality bearings. (Not likely!)
Zooming "a la Phoenix style" does in my testing cause stitching error's everytime! Not major, but they are very noticeable. (Albeit fixable in Photoshop) This method is not recommended by Agnos. Others doing this method (Successfully) are using software that allows manual stitching points.
The "automatic" stitching with Panoweaver 4.0 seems to make better control points and thus small nodal errors are compensated for in my testing (when compared with 3.01 Pro)
I need to see a set of images that cause you problems to help further.
