I was entranced by this camera when it came out in 1948 or so but I could never afford it. Are they still available today (used of course) and can they be easily adopted to handle 120 roll film?

There is a filter advertised on the internet that has eight levels of darkness according to how much you twist the filter. I think it sells for around $50 or so. I remember seeing years ago a Polaroid filter with an arm or small lever on the side which if you turned it one way or the other the resulting image would get darker or lighter. Are these the same?

I’ve heard that the Zeis 24 to 70 or is it 24 to 80 2.8 is the sharpest all purpose lens available. If not, then what is?

OKAY. I GET IT. SO HERE COMES A REALLY STUPID QUESTION. If everybody says that GRAY is bad, including both Nikon and Canon, then why do Nikon and Canon even make cameras for the GRAY MARKET to begin with??? Or are these GRAY MARKET Nikons and Canons simply "knockoffs" that are made in China or Mexico by someone other than Nikon or Canon? What is a "knockoff"? Ex: I have two Rolex watches that I bought for $50 each on the sidewalks of New York City (and I probably overpaid for them).

I'M SURE THAT THIS QUESTION HAS BEEN ASKED BEFORE. Has anyone had any experience with so-called gray market cameras? There could be as much as a $500 savings or more on a quality camera but is it as good as the "US" version? Are there any specific disadvantages of buying a gray market camera even though they are all made by the same company, or are they?

I've been taking photographs since before most of you were born. Back then it was a real hassle to develop your own color film or if you had the time, you could submit it to Kodak and wait ten days to get it back. When digital cameras started to hit their stride I refused to try one of those new fangled cameras but once I did, I never went back. Anyway, my question is: Have any of you tried the Canon 5DS-R? That's the one with 50.6 megapixels. Is it all that Canon says it is? Can it be used with existing Canon equipment such as lenses and flash units? What kind of cards do you use?

I want to thank all of you for responding to my questions, including the guy who got annoyed at me because I failed to say that my question was intended for full frame. Based on all of your responses I am opting for the 24-70 2.8 as my standard lens. I am still considering what to get as my wide angle and extra length zoom.

I had a Minolta Maxuum 9 with a titanium body in excellent condition and a low serial number of 078 that was stolen from me last month. I bought the body for $3,000 almost 25 years ago. Any idea what it would be worth today?

That's because I really hate to drag a whole bunch of lenses with me, let alone having to change lenses at the risk of missing a shot.

I would like to amend my original question by expanding it to;
What is the absolute most sharpest zoom lens available for full frame 35mm format???
I believe that a few years ago Zeiss came out with a 2.8 20-70 zoom which is now available from other companies. Are they imitations?

I would like to know what the absolutely sharpest lenses are. I am in the process of buying new equipment and might switch from Canon to Nikon, depending on the sharpest lens available in full frame format.

I should have specified that she is a photographer with the Dodgers and has been with them for about 19 years.

I presently use a Canon 7D and am thinking of buying new equipment. My daughter works for the Dodgers and she uses Nikon which she swears by.
1. The question is, which is better for general all around use, Canon or Nikon?
2. Does full frame give you better resolution?
