CV 1,9/28 on the M8

It's an excellent lens - very sharp even at full aperture. The only slight problem with it is that it obtrudes to a certain extent into the FOV of the M8 viewfinder.

 

I have both the 1.9 and 3.5 CV 28mm lenses and wouldn't want to dispose of either - I use the 3.5 when a clear FOV is more important than lens speed - it's just as sharp as the 1.9.

I've had my Ultron quite a few years now and I've used on an M6TTL and an M8.

It works very well on the M8, although it's a bit big, especially with the hood fitted. I've coded mine with a Milich adaptor and have the UV/IR filter and the results are very good indeed.

For price and performance, I think you'd have a job to beat any of the CV lenses.

I've had very mixed results with mine. I thought it extremely soft, but found instead that the lens is completely uncalibrated for my M8 (which focuses a 90mm Summi, a 50mm Summi, and even an Industar very well), though has been improved by some tape on the lens focusing cam.

There's nobody to fix the lens in this country, so all repairs are through dealers, and some are less... Reliable than others.

 

What I find most irritating about this lens is that it's quite capable of extremely sharp results, but just not where I want them, reliably. This is not helped stopping down as the focus plane on my lens doesn't seem to be very flat, and moves when I stop down. I'll have to dig up the example shot of the tree that I took the other day-- just an autumn picture of little worth, but soft in the middle (at f/4) , where the trunk (and the tree was 300 feet away) is cuttingly sharp. The plane of good focus isn't as I'd expect.

 

I'd love to try another, but the last lens I returned never came back until I reminded the dealer that he was supposed to have returned it to Japan for repair and adjustment, and he then replied that Cosina had "replaced the lens" and would send me a new one. I'm pretty sure I got the same lens back (with the same problems) but packed in the wrong foam... Just very slimy business transactions.

 

So... Uneven results, but those pictures that are nice are very nice. Those that aren't are maddening, and it's very difficult for me to learn a lesson from such erratic behavior.

 

Then again, that's how I feel about most anything CV these days.

Here's a shot taken a couple of weeks ago in the Jewish cemetery in Berlin. I've included a section at 100%. Neither has been sharpened.

That has not been my experience. The CV Ultron is a very sharp lens for me. Below is a non-artistic shot with a center crop.

Stephen Gandy's repair people fixed my 35 PII quite quickly and well. I guess it depends on one is dealing with. Stephen is in CA, USA.

The little 28 Skopar is also an excellent lens. Higher contrast than the Ultron (for better or worse) and very sharp across its field even wide open. I own both.

Had the same problem, fixed it with a plastic shim (0.2mm thick in my case) glued to the cam. Lens now very good

Anybody outside there who has experiences with this combination? How is the 1,9/28? Is it a good alternative to the more expensive 2,8/28-Leica-sister?

 

 

More non-artistic shots with the CV 28mm Ultron. ISO 160, f/8, 1/250th. Williamsburg, Virginia.

I heartily agree that CV lenses are the ones to beat for performance vs. price. Leica glass is 10 times the price without ten or even double the performance. I have every CV focal length save the 12mm, all for the price of one new Leica lens. Leica has great lenses, and someday I may talk the wife into one, but for now I view the performance marginal for my purposes, and not worth the price difference.

Can you explain exactly what you mean by this. I have the lens and the focus is way off, I really have no confidence when I use it. If there is some home made fix I'd love to try it.

 

Thanks
