practical example, let's look on lenses: 24mm f/1.4, 35mm f/1.4 and 50mm f/1.4.
You attach them to FF, APS-C, u43 cameras and get following effective focals and DoF:
24mm f/1.4 FF = ~35mm f/2 APS-C = ~50mm f/2.8
35mm f/1.4 FF = ~50mm f/2 APS-C = 70mm f/2.8 u43
50mm f/1.4 FF = 75mm f/2 APS-C = 100mm f/2.8 u43
The point is, observed by Wozza and Luka from Fredmiranda forum and others - by attaching wider lens to cropped sensor - you will not get the same magic, 3D - which you have with longer focal attached to FF.
At least when wide open.
When closed down - results are closer.
Cenek, thank you, much appreciated Very nice shot! Love the composition.
Another evening shot in Melbourne with the 24 Lux and M9
The distinction that you're focusing on is the FoV/DoF relationship. Those will be different because they are dependent upon format. That's what the equivalence you are pointing to is concerned with.
The lens' drawing signature is the same in all cases ... it's an optical property of the lens based upon its light transmission properties. Those are invariant.
For instance, my Nikkor-H 85mm f/1.8 fitted to an Olympus E-1 nets a package with the approximate FoV/DoF properties of a Nikon F3 with 180/2.8 lens fitted, but it is smaller and 1.3 stops faster. The drawing (aka rendering) qualities of the lens, however, are exactly the same as they were when fitted to the F3 - you simply see a smaller portion of the lens image circle.
The bottom line is that if you are talking about lens drawing characteristics, you get them given an adequately accurate sensor that allows the drawing characteristic of the lens to be imaged. But if you are looking for the FoV/DoF relationship of a 24x36mm format coupled with a lens drawing characteristic, the only way to obtain that is with a 24x36mm format camera AND a sensor that accurately images the lens drawing. They are two separate things combined together.
I'm not the moderator and while I enjoy the discussion, I don't think it belong in this thread specifically. I will follow the discussion if a new thread is created. I think this topic gets discussed with some regularity actually.
To those you commented on my pics, thank you very much.

Scott, i agree
more photos , less tech talk pls
Cendo: Very nice series of images. I especially like the shot with the ladder. The light in that one is really impressive.
Always giving of herself.
(A cousin is in hospital following emergency surgery. It's still touch and go. Mimi decided since she couldn't do anything else to help, she could at least give blood.)
M8, Nocti 1.0 @ f1.4:
Lloyd, Wozza, Joe, Ed, Gary, Charles - thanks for your comments.
Charles - like the Melbourne streets, especially the first. Enjoyed the processing as well.
Ceh - nice series.
Lloyd - powerful image behind the story, and still with a smile Really hope all goes well.
Picture tells the story
Got a bit of catching up to do... but Mike Woods... your landscape set was quite amazing... I wouldn't mind a few of those hanging on my studio desk :]
Here are a few I took from the past week!
During the final few days of our first studio project. Wesley requested "candid" shots of him. Hillary had a nice shirt.
We concluded our first studio project yesterday with a day of critiques. Everyone gets dressed up for crits :] It was also Miho's birthday... people put up a bunch of balloons around her desk!
Sunset at -10C
Cenek, Lloyd and Mike, thank you guys, much appreciated
Cenek, great series of street scenes!! My favourite are the old man with the accordion and the last shot... timeless
Lloyd, powerful image and feelings. The eyes say it all!
Patrick, love the impromptu captures, very nice!
:P Thanks all!
Ceh... that's a really nice shot... so mysterious!
Mike, my tools? Just an M8 and a 40/1.4 nokton :] I'm finding myself very... satisfied with these toys. I would really want a 35/1.4 Summilux and an M9, but I don't feel the NEED for one. The M8 and 40/1.4 (even if it's not leica glass) make me happy :]

Just working up some images from yesterday....Brecon Beacons, Wales. This is one of the first, early morning light with M8 and Zeiss 25mm:

Mike: Another winner! Really nice.
Godfrey: Both shots are nice; i like the moment you captured in "Communicating", but "Sunning" is special. It has an HBC feel to it. Terrific work.

Godfrey: Great b&w shots!
Patrick: I really like your candids!
Zoomstop: I really like that "home depot" shot!
Here's one that I took a couple of months ago but never got around to posting. Taken with the M9 and Carl Zeiss Biogon 2/35
And four more with the Voigtlander 21mm Color Skopar
Thanks for posting, K-H.
Too many great photos add to this thread to keep track of!
So the M-Rokkor 40/2 has become nearly welded to the M9 for a while, it ain't moving yet. I just un-welded the Nokton from the Ricoh GXR-M and fitted the Ultron 28/2 today ... this coming week that's what I'm going to be shooting with. Should prove interesting!
Thank you all for your comments.
This thread moves at lighting speed! Love to take the time to review all photography and it is always a great treat!
. . . . . keep 'em coming!
The Shed ~ Fort Worden ~ Port Townsend, WA
Leica M9 with Elmar-M 24mm f3.8 ASPH
A few more from the weekend, M8 and Zeiss 25mm...let me know if this is getting boring
A few words on the Zeiss. I wear glasses and I find it a pig to frame properly. I end up peering around the viewfinder like some idiot, and still end up including too much, or not enough :roll eyes: But it's ability to resolve detail is pretty amazing. Anyway, a few images - hope you enjoy them:
Very nice Mike. That lens does have some special qualities, and seems especially suited to the M8. Glad you're willing to put up with the idiosyncrasies, and to share the results with us.
Dan: Nice shed!
Wozza : love those, especially the first two
Mike W : zeiss = neiss!
zoom: I like Home Depot
Godfrey: keep up the good work
I went to the model airplane clubs annual flyin at the Coliseum Sports Centre
I took my family and the M8/cron 50 combo ( I love the retro rendering of this 48 yr old jewel!)
and as we left.................
Really nice set, Robert.
