We're good to 600 RVR in the Q400 (more technically, touchdown 600, mid 400, rollout 300 at an airport like Seattle). I just did one of these last week. You see the runway at 50-75 feet, not much time to transition to landing.
A bunch of our new captains are on "high mins". If I recall correctly, new Q captains with at least 300 hours in turboprops can use Cat II minimums. This could be as low as 1000-1200 RVR, depending on the airport and what exemptions and authorizations we have available.

As previously mentioned... The Q's CATIII mins are 600/400/300. Hand flown by the Captain from a minimum of 1500'.
It can be one of those "this is why I do this" moments, like today. RVR in SEA bouncing between 400 and 800 RVR. Get over to approach when it goes up to 800, then over to final. Final knows the game and won't hand you off to tower until just crossing FINKA. Over to tower and RVR is now 500.. Inside the FAF, so continue. The RVR sensor for the TDZ on 16R is about ~300' left of the TDZ. With the fog rolling through, you get to mins, see the runway and land.... Before you even think about "where's November", it's up to 800+ again... Typical SEA....
I never really appreciated how versatile the Q was until today. 150' above mins as you descend into to fog and get in.

FOM 17.1.7 - Low Visibility Operations, specifically the section "HGS AIII Approach Operations (Q400)", last note at the bottom:
- CAT III approaches and landings may be continued if, after passing the FAF, any required RVR report decreases below authorized minima provided the HGS rollout system is operational.

You may continue at Cat1 or Cat2 approach if you are passed the final approach fix and weather goes below minimums in the US. (Not true in many foreign airports). If you are flying a Cat3 approach in the US a go around is mandatory if the weather goes below minimums even after the FAF/FAP.
