Lenses / Lens and filter options for landscape photography
« on: October 16, 2012, 03:44:41 PM »
I currently own a Canon 5D mkIII and five lenses including the Canon EF 14mm f/2.8 L II, Canon EF 24-105mm f/4 L IS USM, Canon EF 70-200mm f/2.8 L IS USM, EF 100mm f/2.8L Macro IS USM and Canon EF 50mm f/1.2 L USM.  I am an amateur that shoots family portaits, woodworking projects and occassional auto and air shows, but I primarily enjoy hiking and landscape photography. 

I am contemplating the purchase of a new landscape lens (TS-E 24 II, TS-E 17, 24-70 II or Zeiss 21mm) and believe I need to incorporate use of filters to improve my landscape images.  The cost of the 100mm HiTech holder, grad filters,  circular polarizer and adapters tallies to over $1K.  As a point of reference, the cost of a 82mm quality variable density filter and circular polarizer from B&W is about $600. 

My understanding is that grad filters limit the dynamic range of portions of an image to work-around the limitations of the imaging sensor.  If sensors had sufficient dynamic range, use of grad filters would be unnecessary since the gradient effect and tonal modifications can be applied in post-processing.  I understand that the effects of polarizers and uniform darkening filters cannot be emulated in post. 

Here are my questions: 
1. My perception is that use of a Lee or HiTech filter holder and plates will require more setup time and more fragile than screw-on filters.  Do the virtues of a filter holder system, such as the HiTech outweigh the benefits of screw-on filters?
2. If I were to invest in a new body and lenses capable of higher dynamic range to augment my current gear, would this substantially alter the makeup, need for and cost of a filter system?  In other words, is there another equivalent technical solution?
