Today I purchased a Swarovski DCA to fit my 20-60x eyepiece, The inner adapter which fits over the eyepiece fits by turning the outer screw and this secures a rounded inner clamp onto the eyepiece (Works well without marking the eyepiece). The outer adapter (holds camera lens) which fits onto the inner adapter fits by turning the screw which has a nasty brass end which grinds onto the inner adapter, marking it. I'm sure this will make a right mess of the adapter after a little use. Are all swarovski DCA's this way?

It would seem so, as the DCA that I bought is exactly as you describe. It does seem to be a flawed design, and I would have expected better from Swarovski. Having said that, the adapter does work very well, and I find it quick to use, which is important for digiscoping.Merlins said:

I've been using the DCA for about three years now and it's seen a lot of use. I leave it on the scope almost permanently. There's no problem with the fitting of the outer sleeve over the inner one and no mess. The inner sleeve is hardly marked. The knurled nut on the outer sleeve just needs tightening enough to grip the inner one - it doesn't need to be really tight.
The nut on the inner sleeve is the one I take issue with. You have to tighten it enough so that you can turn the inner sleeve to adjust eyepeice magnification but if you overtighten it the eyepeice is warped and you can't adjust zoom. If you don't tighten it enough it wobbles and slips around the eyepiece defeating it's purpose.
I like the principle of the DCA but maybe it's attachment to the scope eyepiece could have been better thought out. A three point attachment to the eyepiece would have spread the load better.

Hello Ian,
The DCA that I have holds the eyepiece wery well even when slightly tightened, no problem but the first day I tightened the outer screw slightly it marked the inner piece. I think the DCA's have changed a little since they were introduced, I think there was a fixed and a zoom but now there's just one which has a plastic curved plate that tightens onto the eyepiece. Does your DCA have the plastic curved plate in it?
