For microphones above 22mm, Duo-Lyres® are usually the best choice: they will hold mics up to 34mm in diameter. We have 30mm Single Lyre variants, but these do not feature our unique rubber insert which is incorporated in our other Lyre systems to provide superior grip and isolation. For further information on our range of Lyres, please visit the following page: http://mymic.rycote.com/products/lyre/modular-lyre-upgrades/   More general information is also available in the following video:

Yes: we have Hot Shoe Extension Bars in 10cm, 20cm & 40cm versions that allow you to do this. Product details are as follows:   10cm Hot Shoe Extension Product Code: 037303 http://mymic.rycote.com/products/10-cm-hot-shoe-extension/   20cm Hot Shoe Extension Product Code: 037705 http://mymic.rycote.com/products/20-cm-hot-shoe-extension/   40cm Hot Shoe Extension Product Code: 037702 http://mymic.rycote.com/products/40-cm-hot-shoe-extension/   These bars connect to the camera via the main hot shoe adapter, and allow further hot shoe devices to be connected to the bar itself.  

Both INV-7 series mounts will work well with the C617: the choice really depends on how you will be using the mic (in particular, whether any slip-on wind protection will be applied in the form of, for example, a Classic- or Super-Softie®). If slip-on wind protection is to be used, the INV-7 HG MkIII would be the best choice, since it is designed to support the mic from the rear and allows a reasonable amount of weight to be added to the front. The standard INV-7 supports the mic along its length, and can only handle a foam windshield + Windjammer® at most.   More information about our InVision INV-7 series of mounts can be found here:

Unfortunately, we do not currently manufacture a BBG windshield for the Røde NT4.

The InVision Video mount incorporates a Duo-Lyre®, which will hold mics with a diameter of up to 34mm. Please note that we do not recommend using large, heavy mics on a camera shoe, since this is often a weak point. Using a large and/or heavy mic with the InVision Video Hot Shoe is not recommended.   More info on the Invision Video Hot Shoe can be found in the following video:

For the 40/55 Foam, a Special 60 Mini Windjammer would be the most suitable solution.   This is slightly larger than the foam itself, but a built-in drawstring will allow you to tighten it.   Special 60 Mini Windjammer Product Code: 055307 http://mymic.rycote.com/products/special-60-mini-windjammer/

Product codes and further info can be found here: http://mymic.rycote.com/products/15cm-super-softie-19_22/ In addition, we also manufacture a Super-Softie solution for the CMIT 5 as part of our bespoke, Perfect for range, which is further optimised in terms of weight and overall size. More info on this product is available in our Knowledge Base here.

For the E 614, we'd recommend the following: 5cm Super-Softie (19/22)
Product Code: 033205 More information on this solution (including a list of other recommended mics) is available here: http://mymic.rycote.com/products/windshield-solutions/super-softie-windshield/5cm-super-softie-19_22/

The hot shoe extension will not cause any issues with the D800, since the support bar is non-conductive: there cannot be a short circuit.
