That doesnt sound cheap
I take it you ordered the resin filters as opposed to the pro glass ones
I can see why you ordered the square polariser, didnt realise the cicular one was £200+,
I am going to have to get a set at some stage, espescially once i get an ultra wide angle lens, More expense.
The reason for ordering the "Square" CIR POL rather than a "Round" CIR POL wasn't really for cost, more for flexability. So the "Round" filters slot on the front using a P-Ring (which rotates and uses up a slot)
Lee in their continuing efforts to provide filtration for the widest range of cameras and lenses now offer the following Polarisers:
Linear - standard type polariser used to reduce reflections or intensify blue skies.
Circular - modified to be used on cameras with AF or complex metering systems.
Each of these types is available in in 2 styles:
100mm square - 2mm thick square filter to fit into a standard Lee resin filter slot
105mm screw in - used on the front of a Lee holder using the accessory front ring
So I have ordered a "Square" CIR POL rather than a "Round" CIR POL (so, Circular rather than Linear). i.e. it's not related to the shape of the filter! (you might have already known this, but I didn't until a few days ago.
The "Pro Glass" ND's are not Grads. These are just 100x100 ND's. The Lee Grads are either Resin or Polyester.
The Lee system is very confusing. Hopefully, I have ordered correctly. If not, it will make a grown man cry.
