This setup takes advantage of the 4.6x crop factor of the Q7.
All images are not cropped to get any more 'magnification'.
At the most its a crop of 5-10% for composition purposes.

Excellent macro works! This lens is 1:2 on full-frame, isn't it? Did you use any tubes?
BTW your is the first Q7 I see on this forum. May I ask how do you like the camera? Crop factor aside, is it a good system for manual focus lenses? |

Thanks everyone for the kind comments.
I do think that such a high pixel density sensor is very critical on lenses.
From my usage so far my guidelines are :
1. Lenses reviewed for low res in the center in lens reviews are out.
2. Lenses with bad CA are out
3. Fast lenses with good resolution wide open and even better resolution stopped down by f4 are safe bets
4. Q7 suffers from diffraction a bit later than Q/Q10; so lenses can go f5.6 and f8 is a bit better than Q/Q10
5. Diffraction is not a sharp cliff so f8 and f11 is ok so long as it gives the DOF required. (f16 wasn't good on Q though)
Many normally used focal lengths don't seem very useful on the Q (mho) (eg. 35mm; 50mm; 85mm)
Too long to be used for many situations and too short for the extreme stuff.
Well, at least I've not found a use for them yet.

Sorry, I am not familiar at all with calculating the magnification ratios.
Its like having to crop off 3/4 or more of a FF o/p at 1:1 to get magnifications like these.
And the Q7 o/p which is still 12mp and uncropped certainly looks better off than doing that to a FF/APS-C o/p.
No tubes are necessary.
Just the adapter for the K-mount lens.
It has the advantage of working from infinity to MFD unlike tubes and close up lenses.
I wrote my impressions of the Q7 here.

Awesome pictures! What a great lens the Viv 55/2.8 is. And very versatile because of its 1:1 ratio.
I've got a couple of 55mm macro's at the moment. A Rokkor, a Nikkor 55/2.8 and the Vivitar (or actually the Panagor version).
I will soon put all three to the test in a comparison! |

Thanks for the review. People who own a Q seems to talk about this fun factor of using a really tiny interchangeable lens camera for everyday snapshot. I almost pulled a trigger for an Evangelion Q10 but Q7 was announced so I put that on hold. Your post make my GAS relapses. Fortunately for my wallet it is still not available in most places, especially the bright color ones.
I am still curious about using manual focus lens with this camera. Specifically, how good is the manual focus assisting tools like magnify glass and peaking. Is it convenience to activate these tools? |

I wish my Nikon V2 had focus peaking... it'd elevate the camera's practicality greatly.
I'm very much committed to Nikon, but I could see myself getting a Q7 as a backup camera since I'm starting to collect more c-mount lenses in general... |

There are some limitations because i'm using a m4/3 Panasonic G1. Resolutionwise not a bad camera though.
I think the Nikkor will probably win, because it has a reputation of being one of the sharpest macro's in this focal range, but I think the Vivitar could be pretty close. |
