15-30mm filters

Cheers Jeff, They do look pretty sturdy alright, hard to find stockists though, And they are no cheaper than the other 3 or 4 that do 150mm filters.

I have been thinking about this, too.

I have the 15-30, mainly for gig photography but, obviously, it's also the lens for landscapes.

I have, already, the Hitech 100mm system, which I have used on an APS-C system, the K3/K5 and 12-24. I can also use it on my K-series of lenses.

I have decided not to invest in the bigger filters as I don't use them often enough and, if I decide to actually use the K-1/15-30 combo for landscapes, which I probably will, then I will bracket if the conditions need it.

When I go to Scotland in May, I will be taking both systems, and will probably take shots with both systems in parallel. That should produce some interesting comparisons.

Looking forward to seeing some of those shots.
Think I'll just hold off for now anyway and enjoy using it as I am.
👍👍👍
