I would recommend you buy a larger CPL filter and a step down ring.. As quite a few Pentax lenses now have a larger filter size,,

Or the 85mm f1.4 ?

In my experience of gig shooting wide is better than long. Manual is better than zoom. Full frame is better than crop sensor. Lens speed is everything as lighting is never at a premium. Pre plan the shot, pre focus the shot and wait for it to happen..!! I to would choose 35mm f1.4.

The best of luck with your new gear. Sorry to see you go, if a little understandable...!

I have purchased the Kase range of round 82mm Polorizers ans toppers. Not cheap, Quality glass no complants at all

Dont use Live view get a flash meter, Set the lights correctly without guessing....!!

Yes a very well done on your achievements Alistar. Very much deserved. Love no 8....

I dont no much about macro shooting.. But im impressed with the images..... Well done...!!

ND filters is a tricky subject. When it comes to what kind should I purchase. The first and obvious question is "How much do I intend to Spend on them ?" Then how often do I intend to use them..? And thirdly . Will I ever purchase equipment that will leave the system redundant. The latest Pentax lenses being 82mm. Requires a 150mm filter.

Do I want to purchase plastic filters or glass ? Plastic filters scratch far more easily. Transfering to your images. Glass breaks. If or should I say when you drop them in the field. (unless you use Kase filters)

All the cheaper filters will leave your images with colour casts to them. But if your a proficient Lightroom or Photoshopper these are easily removed. Saving you money if not time..

Which shape ? Well if you eventually intend on adding graduated filters to your system. You will have to select the oblong version. "Z" system. As this type is so much more variable and easier to use. Round filters seal the light far better. To the lens. But not as conveinient to move out the way when focusing.

I personally wouldn't recommend using the fader system. As the ones I have come across. Don't extend to ten stops. Leaving you another filter still to purchase. They also can be easily moved and twisted. If attaching graduated filters to the front of them.

At the end of the day. The decision can only be yours. Only you knows what you want out of the system.

My recommendation...
3 stop ND
6stop ND
10 Stop ND
Polorizing filter.
0.9 Graduated filter.

Nice backgrounds... Make the shots
