<p>Thanks, Ian, looking good. <br>

David</p>

<p>Always interesting when someone has to be negative when there is no reason to be. I guess andrew and JC have all the right answers and we should listen to them.<br>

Have a great day everyone else,<br>

David</p>

<p>What is best in your experience? I've tried both.<br>

Changing the shutter speed from the "correct" exposure to blur water (falls).<br>

Or changing both the F stop & shutter speed, to maintain the exposure, while blurring the water with the slower shutter speed.<br>

I use film if you think it makes a difference.<br>

Just wondering,<br>

David</p>

<p>Thanks all.<br>

David</p>

<p>Thanks for all the input, really.<br>

Just to make sure I understand:<br>

If I need +200 glasses from the drug store to read at, say, 18 inches. Would that equate to +2 diopter for the waist level finder on my RB 67? Which would also mean if I needed +100 glasses is +1 diopter in the same finder?<br>

Thanks once again,<br>

David</p>

<p>Need to find diopters for the waist level finder.<br>

Looking for all of them.</p>

<p>Thanks,<br>

David</p>

<p>Thanks much Stephen. I'll look and figure it out.<br>

David</p>

<p>Thanks, Stephen. The medium format is the RB 67 Pro S. The 35 MM is Nikon F body.<br>

David</p>

<p>This came up recently with 35MM film camera but I think it applies to medium format also, both single lens reflex.<br>

I need 200 + readers to read a book plus distance vision is not so hot either.<br>

If I use my naked eye, doesn't the lens focus the image I see in the finder, and it should come out focused when printed? Or do I need to use my readers to see the focused image as I need them to read?<br>

Kind of confused. I thought the camera / lens would take over and my poor vision otherwise would not affect the final image. In some of the images I just made, I used the distance scale on the lens barrel but not sure what that did.<br>

Thanks for your thoughts,<br>

David</p>

<p>What is the real difference / benefits to the Mamiya "K/L" style of lenses in the various lengths?<br>

Thanks,<br>

David</p>

<p>Many thanks to all for sharing.<br>

David</p>

<p>I have some outdated 120 & 220 film. It has been stored correctly in the refrig.<br>

When using this film, besides bracketting, would the correct exposure be a little longer? IE, 160 speed be exposed as 100 speed, etc?<br>

Thanks,<br>

David</p>

<p>Thanks so much guys !</p>

<p>Please describe the "fit" of the accessories for these two Mamiya's to each other. IE. film backs identified as "SD"-Will they operated fine on a Pro S and vice versa? etc.<br>

Thanks,<br>

David</p>

<p>I'd like to know what parts / accessories that are sold as "SD" can be used, without adapters, etc. on the RB PRO S. Seem simple to me to determine, but I don't know. Mamiya doesn't publish anything that I've been able to find. It would also be nice to know what RB Pro S parts can be used on the SD model.<br>

Thanks for your input</p>
