The Lee 150 system utilises the same mounting system for the Pentax 15-30 as the Tamron 15-30 (no surprise there). There is no vignetting, the filters are BIG

Originally posted by Pentax Syntax it might make more sense to build your filter system around the 24-70
I would respectfully suggest the opposite, and I say that from experience.
The point is that the 150 system can be used not only on the 15-30 but also on any lens that has a smaller diameter front element, ie the 24-70 and every other lens I own. Far cheaper for Terry to base his filters round the 150 system and use that on all his lenses.
If you start with the 100 system for the 24-70 and then decide you want to use Lee filters for the 15-30 you will have to buy a new lens mount; filter holder; and filters. More than doubling the cost. Using the 150 system on other lenses requires only the expense of the mount adapter.
Did I say I found this out by experience ?
