there are allot of mics to choose from and not only schoeps which is overpriced mic if you use it for dialog , and it better as it would come with cut 1 ( another 450 usd ) to eliminate the boom rumble .
so its not really oktava to blame but more bad shock mounts people use and no ability to cut everything under 75 hz .
there is a list of mics our rentals have and we have exellent results with
mkh-50 - quieter then the schoeps -more directional , has low cut filter
better for humidity situation - the down side it one capsule mic so you need a mkh 40 for shots you need wider capsule -about 1400usd
akg 480 + 63 hyper and 61 card - grate sound , low fq cut off , have swivel joint - sounds fantastic - cost half the schoeps ( 650-800usd) , additional capsules for 200
microtech gefell m210hyper , excellent sounding mic -1100usd , low fq cut off
additional capsule( 200 card)-about 650usd
mbho 604 + ka-500 card , very good sounding mic for dialog --850 usd
the shortest , have allot of capsules to choose - additional cardioid - 280 usd
have swivel joint to add - maybe one of the best bangs for the buck
the 603 body which is standard is about 100$ less .

chinese mics i used for about 600 grand production days - same factory that makes for sontronics ( check their page|) and others - 200usd for 3 capsules mic , low fq cut off , good for boom

by the way i have 4 schoepses as well but they where bought years ago to record mainly music where they are really grate , but for dialog - just listen to others and save money
