I'm curious about microphones which feature a wide frequency response, ie. over 20kHz, for recording SFX at 96 or 192 and later pitching down.
What's out there?
What have you used/own?
What do you think of them?
Thanks in advance!

Sennheiser MKH 8020, 8040, and 8050 record out to around 50kHz. They are outstanding, quiet mics.
Schoeps MK capsules with CMC-6 XT bodies record out to 40kHz. Also amazing mics. A little more self noise than the Sennheisers, but they sound great and handle mid range frequencies very well.
The Sennheiser - MKH series are analog-boost-eq inside the mic preamplifier in order to get an extended frequency response. I used MKH - 8020 @ 192kHz for slowed down fx and I get high frequency noise. Neumann mics don't have this eq boost, the highs may be more natural and less noisy. I don't know for Schoeps and DPA.
I have Sennheiser MKH 8040, but after slow down from 192 to 48 there are much more hi frequency noise, than signal, so this trick don't work well with this microphone.
UPDATE: Just try other recordings at 192 with 8040 and found that they quiet!!! I will make more research with other recorders, it looks that I am wrong about 8040 and this problem in my SXR4 or I have defected mics.
