Definitely looking better now, but as you say, still a bit there. Very nicely seen :thumbs:

Thanks Jack and thanks for your noticing the color cast.
Best,

Hi Peter,
I used it quite a bit. As a matter of fact, I was surprised how much more I used the 80 over the 35. I think it's because the shifting makes the 80 into about a 53mm in 6x6 terms.

The T/S was terrific; I used it in images nr. 1, 2, 3, 6, 7 and 8. Just about every shot. Using it with shift was perfect; great near/far capabilities. As I'm not familiar (and probably not patient enough) for focus blending, the tilt worked perfectly.

I also liked the fact that I could turn it 90 deg to make it a swing adapter too. Though I didn't end up with many images using this swing approach, I will work on it more. I'll use the swing with rise fall.

Finally, being able to put the tilt on either the front (lens) or rear (back) side gives me more options on controlling perspective. Using it on the rear slightly emphasizes the foreground, which I often like. But sometimes (in the river shot, that isn't desirable so putting it on the front works best.

Hope this helps,
Bob

Thank you Bob for that additional information. Do you have the 6 degree or the 12 degree adapter? And I was wondering if you had anything to say about the difference between the two. I suppose the 6 degree gives better control for fine adjustments, at the expense of not allow for as much tilt/swing. Thanks again for your comments.

Cheers, -Peter

Hi Peter,
I have the 12 degree adapter. Since I don't have the 6, I don't know the difference in degree of control between the two. The 12 came in handy as it turned the 80mm into a bit of a macro lens with good near/far.

Best,
Bob

Thanks Bob, good to know.

Hi rga,

I had a question about your mention of the shift with the 80mm lens. You mentioned that the shift on the 80mm lens makes an equivalent 53mm lens. Can you tell me how this works? This would help me in selecting lenses for use with tilt functions.

If you can give me an email address, I can attach the spreadsheet I made for your review.

i agree regarding the need for a good spirit level. i find the one on my cube is inaccurate. besides, a good spirit level is best used on the camera body but the ones on the max are very small. do you know where can i buy the EBISU CRYSTAL LEVEL online?

rh

No sprit level reading of any gear like CUBE , ARCA , ALPA or whatever camera or QR gear of any brand you use , compares to another .
Many scenes do not require a very precise leveling , but some , for example in architecture photography , do .

My method with the ALPA STC is , that I ignore the reading of CUBE or STC and use my EBISU CRYSTAL LEVEL and measure directly at the camera body . 3 ways ! ! ! if required .
Have a look to EBISU CRYSTAL LEVEL ED-10CLS in internet .
Leveling this way takes a bit more time , but is very precise , as much as you can achieve with a 10cm long spirit level .
If you use an ALPA with a Short Barel lens , it is very easy .

Acratech makes a bullseye level that appears to be accurate. I've checked it with a high quality carpenter's level, as well as the level on my RRS leveling base.
