A friend has generously loaned me a Canon IVsb2, along with a Voigtlander 21mm/f4 and 50mm Nokton 1.5 in LTM, and also a Leica 21mm external finder. I thought I’d start this thread to share my impressions of shooting with this camera. I’ll add more details and image samples as I progress. So far, I’m about half way through the first roll of AP400 (Tri-X). I hope to be able to upload image samples to this thread in about a week (I realise pictures taken will only reflect the lens, not the camera, experience).

First things first - it’s a beautiful camera! I’ve always liked the look of Barnacks, and this Canon copy is very attractive, with slightly more angular design. When you pick it up it feels very solid in the hand, and everything feels precise and tight. I have small hands, and the dimensions and controls feel just right to me. The only other LTM camera I’ve owned was a Fed-3, and this camera is a small jewel compared to it. I also own OMs, but the Canon IVsb2 feels more solid than the OM. Unfortunately I can’t directly compare the handling with a Leica iii. I also have an M4 on loan, and this little Canon feels much better in my hands, probably because my hands are small.

My friend wisely sent me the manual in pdf and I’m glad I read this before attempting to load the camera. It took me 4 or 5 tries to load the film correctly - I had trouble getting the film cassette to sit down far enough in its cavity, it seemed to be springy when I tried to ease it down, settling about 5mm above where it should sit. The lower edge of the film leader became damaged because of this, at the sprocket locations, when I attempted to ensure the film was engaged in the sprockets by taking up the slack with the rewind knob.

The camera comes with a spring loaded take-up spool which I found easy to use. After my initial difficulties the film engaged in the sprockets and all was well. Loading the camera involves feeding the leader into the take-up spool and then easing both film cassette and take-up spool into the body, ensuring the film settles across the gate while you do it. You then gently turn the rewind to make sure the sprockets are engaged. I suspect I won’t have any further problems with film loading, now I know how the cassette should sit in its compartment.

The viewfinder is typical small Barnack size with a coupled rf patch that (in this camera) is clear and contrasty: very easy to focus. This viewfinder is quite bright. The great discovery is the switchable magnified viewfinder settings (up to 1.5x) which enable very accurate focusing. Used in conjunction with the Leica 21mm external finder, this made focus-compose a painless procedure with the CV 21mm: focus at 1.5x magnification, then compose with the external finder.

On this camera the knob-wind film advance is very smooth and the shutter sound both satisfying and quiet, not much different from an M4. Shutter speeds go from B to 1/1000, with slow speeds on a second dial on the front of the camera, to 1 sec. The manual recommends not leaving the shutter cocked, to avoid stretching the spring. My first impressions are very favourable - the camera just feels good.

So far I’ve only shot half the roll, all with the 21mm. It’s the first time I’ve used this focal length, and I’m finding it a lot of fun. It’s forcing me to get up much closer to subjects than I normally would.

The camera does not get much attention as it's quite small. I got a few curious looks and some smiles when people realised it was a vintage camera. Certainly nothing like the response one gets with a DSLR.

Here are some pictures of the camera, with the 21mm finder and CV21mm/f4. Feel free to ask any questions and I’ll try to answer them as I go along.

All Canon LTM rangefinders are nice looking and built really well.
I don't know what are they thinking not releasing a digital camera that looks like those. That would be going back to their roots... in a good way.
 
are you sure that's a canon II?

seems exactly like my IVsb2 (said to be the best of the breed) -- it looks like it has all the bits:
-flash rail on the side
-high shutter speed
-slow shutter speed dial
-film-advance ISO reminder dial
-shutter speed able to be set w/out the shutter cocked (central cut-out with arrow indicator)
-the 50/100/135 adjustable finder...
-looks like it also has the large finder exit-pupil of the -2 designations with the improved de-squinty-ness (the non -2 models are all SUUUUUUUUUUPER squinty, as opposed to just sort of squinty)




edit: ah, seems like you fixed your original assessment. anyways, welcome to the club -- they're totally awesome (all the above modifications make them supremely usable in the world of Barnacks/LTM copies)
 
Nice write-up, Lynn. I really like shooting the IVSB2 for a lot of the reasons you state (disclosure: I'm a Barnack fan). The adjustable magnification vf is very useful for fine focusing. I also appreciate the quiet shutter. Yes the vf is squinty and it's a pain to load, but it's still a fun camera to shoot with and easy to carry.
 
I had exactly the same camera - lens combo a few years back. Such fun to use. The camera feels like a block of iron in your hands. As a matter of fact that was one of the reasons I chose to give it away. Imagine pressing an icy metal object against your chin in -20C...

Thanks for posting pictures of the camera you're writing about.
As a relative newbie here, I find it a bit frustrating when some of the posters here assume everyone knows of what they speak, be it lenses or cameras. As they say, a picture is worth a thousand words. I look forward to reading more of your experience with the Canon.

Now I feel like an idiot.. the loading problem described above was simply because I didn't trim the film leader! It needs to be 4" before reaching full width..
 
I've processed the first roll (AP400, re-branded Tri-X) from the camera, so time for some more observations and thoughts:

The frame spacing is very tight in this sample - about 1mm between frames. This means close attention is needed when cutting the negs into strips. No room for error!

Exposures were even across the frame, meaning that the focal plane shutter is working correctly and is quite accurate in maintaining a constant width gap between the curtains. It also makes a very satisfying but quiet "clack" when fired. No-one close by seemed to notice it.

The shutter speed adjustment is easy to use (lift, turn, and settle into the selected setting) but slower than the click-stop dials of more modern cameras. This doesn't bother me, as for any given (hand metered) lighting conditions, it was set-and-forget, with any small adjustments in exposure made with the aperture (I was shooting with a 21mm so DOF was not an issue).

All controls on this camera feel smooth and precise. A real joy to use. I also love the solid mass of the camera. It feels the antithesis of modern planned obsolescence plasti-crap. Much more solid than an OM.

The camera was loaned to me with a leather wrist strap, which I find ideal. I'd definitely get a wrist strap for any similar cameras (including my OM) after using this.

Next, some pictures taken on the first roll with the CV 21mm f4 - a learning experience in itself.
 
Working with a 21mm for the first time was an experience in learning to get close enough. The Canon IVsb2 allowed me to shoot unobtrusively, although I doubt this girl would have noticed me standing there.

In situations like this the 21mm came into its own. The cafe is in a refurbished boat shed and I wanted to catch the view as well as the ambience. No-one took any notice of the little vintage camera.

21mm will fit in an awful lot. The Canon IVsb2 is easy to carry when rock hopping around a cliff top. The CV21mm f4 does a good job shooting directly into the light.

Here on Manly beach in Sydney I would normally have used a 35mm or 50mm for a shot like this. The 21mm forced me to get much closer, but it gives a much more expansive depth to the picture. I like it! This has been cropped a little to remove a person standing on the right. It’s hard to exclude picture elements when the fov is so wide.

It didn’t take too long to get the hang of seeing with an ultra wide. I would have preferred the couple on the bench seat to be facing the camera, but then I would’ve missed that basket. No-one seemed to notice the little Canon IVsb2 - it’s a good street camera as long as you meter and set the exposure first.

Nice photos, Lynn. The frame spacing you mention is normal for these cameras. My Leica IIIc is the same in that regard. The up side is that you can squeeze an extra frame or two out of a 36 exposure roll.

I keep wondering if I should give 21 a go...
 
My feelings so far:

PROS
- small, solidly built
- works like a swiss watch
- inconspicuous in public, generates friendly interest/curiosity
- magnified viewfinder makes RF focusing easy
- feels good in my (small) hands

CONS
- must trim film leader before loading film
- loading film is much more fiddly than cameras with a rear door
- adjusting shutter speed requires lifting dial, turning and re-seating, not practical to do this without looking at the dial and taking the camera away from the shooting position
- external viewfinder necessary for wider lenses than 50mm. Viewfinder magnification settings are for 100mm and 135mm.
- knob film advance and rewind, rather than lever.
- narrow frame spacing of approx. 1mm (on this sample)

My thanks to Peter for the generous loan of his camera and lens. I will be sad to have to return it.
 
It is not necessary to trim the film leader if you set the shutter to T, open it, remove the lens, and gently guide the film into place while the shutter is open. Youxin Ye advised to follow this approach. Takes a little longer but is foolproof.
