Randad, you realize this opinion is crucial to a decision question from 3 YEARS AGO??

OP has never actually said what the drive capacities are. His statements are a bit ambiguous but most likely come down to 111GB of file space used on his SSD and 1.8 TB used on the data drive. Calls for 128GB drive being too small are probably hitting your tee shot out of bounds.

they might, but once again, no relationship with photography

This is not specific to this lens. The DSLRs have upper limits as to lens maximum aperture and ability to autofocus. I suspect each of these bodies can handle up to f8, with at least some of their focus detecting spots. Now, when you add the 1.4x teleconverter you take away one stop of light. When you add a polarizer (whether circular or not) you take away somewhere between 1 & 1.5 additional stops of light. Chances are that using both, especially at the longer end of the zoom range, will diminish or eliminate all hope of autofocus.

Tracey. For the most part you really don't load up lots of new programs. If for instance your SSD is 500 GB, it's likely you will never fill it with programs. Now, those photographers with piles of fat photo files will fill up drives, and that's why you put those on larger, but slower drives.

There are different kinds of hard drives. More modern machines with 2 drives tend to have a somewhat smaller solid state drive (SSD) plus a traditional spinning platter drive. The usual suggested plan is to leave the smaller drive, which is much faster, for program storage and to put images on the larger but slower drive. Then you use a separate external drive as your first backup.

My favorite boulder, along the Salmon River near Mt. Hood, Oregon

Palouse Falls is far from obscure! Leave your car at the State Park lot and walk a short ways to an overlook. Double check distances to see if it makes sense within your travel plans.

coj, sometimes that is enough, often times it is not. depending on the conditions may also lose considerable sharpness to diffraction losses.

Focus shifting became available on the D850, not the 810. I doubt the 500 has it as a feature. The work around is to take your slices manually. There is all kinds of guidance as to how to do this generally on the web.

The classic area is Steptoe Butte outside of Colfax. I believe there is photographers guide to the area available through the Chamber Commerce/City or County.

As promised. Here is a sampler from the west side of Mt. Hood amidst BPA's transmission grids.

Best display ever here in Oregon. Will post images later.

Jerry. Your z8 should work using earlier varieties of the Nikon en-el15 as long as they say li-on20. Series a & b also work as well as the new c ones.

Yes it is more persnickity as to manufacturer. Not sure about z6.

Yes and no. The term is a misnomer. I view at 100% extensively. But individual pixels are only apparent at 200% and above. That I dont need.
