Yes, still experimenting with "scanning" film negatives in this manner. My last batch I used the 65 on its own, but really I think it would be better with the Marumi Achromat Macro adapter to get true 1:1. (I forgot I had it when I "scanned" my last batch)
How about macro bellows, did anyone try them with slides. They don’t look overexpensive and as a bonus they come with the rails that would ensure a stable setup with a good way to attach the slide holder.
Best to get a true 1:1 optic when scanning 135 film on FF sensor. Even after stopping down, edges can quickly lag with extension or diopter on a 1:2 or standard lens. My go-to for scanning at the moment is the Sigma 70/2.8 1:1 macro which is needle-sharp from the get go.

The first is f2 200 iso100. Mounted on a tripod and a timer used. Contrasty natural light so in this you can't see so much of the contrast loss. The second f4 50 iso100. IS off. Even on the EVF wide open you can see the difference. 3rd image uncropped of the f2 shot. Second full sized f4.
On my computer screen and even viewing the image once taken on the EVF the difference is more obvious.
So I wonder, since I have read a number of times that wide open the lens is excellent, does anyone see much difference when stopping down to f4 or 5.6.
Just looked under light through the lens. Surprised, there is dust on the inside element. Really surprised by this. ...Show more →
Hate to ressurect an older post but I received my CV65 in October and have fallen in love. I've recently discovered a huge amount of dust. Seeing as how I do a ton of long exposure, sunrise/sunset type photos I'm seeing the dust spots everywhere at least 15-20.
Have done what I can to baby this lens since day one, even kept it in a nice rubber case. Purchased through cameraquest and since they're an authorized retailer I figured they could help/direct me to take care of this. But all I got was responses claiming it's my sensor.
Have tested many of my other lenses (vintage 70-80s) and they have no issues with same testing method. Sad sad days for me as my favorite lens is out of commission.
What do you guys recommend for taking care of this? I don't think vacuuming it or using those rocket blowers will help as it's snuck it through the gaps in the focusing element and body. I literally was in tears when I confirmed it with several tests.

Are you absolutely sure it’s not your sensor? The chance of dust spots in a lens showing up are very remote.
Remember that conditions that show sensor are also varied, which makes comparison with you other lenses difficult.
It’s dependent on many things, but focal length, aperture and focussed distance all need to be the same.
The closer you focus, the more likely sensors dust is to be visible in an image. And the 65 focusses very close.
So find a similar fl lens, perhaps a fifty, focus it at the same distance (perhaps whatever is mfd of the lens that focusses least close .. say 50cm so set them *both* to 50cm in manual focus) set the same small aperture (f16) and shoot a blank wall out of focus (say a few metres away and u are focussed at 50cm) and you may see the same spots. Warning: you will certainly see many scary spots.

It won't hurt to try again and be more specific neither focus range. When previously tested I didn't try varying focus points. But I'll make sure to try and match them close as possible.
I'll use my 57mm and my 50mm and retest.

I would stop down to 16, focus at infinity and shoot a clear sky. You can see if it is your sensor. Do you see dust in your lens when you look through it? You would be focussing through the dust anyway. I would suspect the senator.

At work right now but yes, I used a LED flashlight and shined through the lens. Tons of dust, reminded me of looking at a petri dish. Looked as if it were floating which tells me it's between the elements. There WERE some dark black pieces in there I could see using the white wall looking through the lens directly.
Not sure if I was wrong to do so but I ran the hot water in my shower and waited a minute or and I true to blow using the rocket blower and some dislodged and some relocated itself within the lens. visible debris in the lens with the naked eye is the issue for sure. But I want to be 100% the lens is an issue before I out anyone like Stephen at camera quest through any extra work.
Workflow and fast operation of the Voigtlander, how do you apply yours?
I now have this lens for a week, very happy with it.
I´m interested in how others apply their worflow and lens control for general use.
My application is no rocket science, no auto focus peaking, no auto magnify, I put this on a custom button. Magnify with custom button AEL when I press the AEL button I get first step magnify, press again second step magnify, third press back to normal view. This takes far too long and third step of magnify is often too close and not always desired. In order not to have to go further than the second step magnify, I apply the following workfow:
The aperture ring on the front is very pleasant, my default setting is as a starting point: aperture ring on F2 it is now only possible to turn to the right, no guess.
Set desired aperture.
The focus ring as a starting point set to infinite, it is now only possible to turn to the right, no guess.
Focusing from infinite to say one meter distance is a very fast and short throw.
With my eye on the evf i put the focus square on the subject, double tap with the right thumb on the screen this gives first step magnify to the point where the focus square is placed, double tap again, the evf jumps back to normal. Ready to shoot.
Sometimes i use peaking in between, and if there is enough time I use second step magnify.
Does this workflow make sense or is there a simple/ better way..love to hear your thoughts.

If you use only the first tier mag., you can just press one button to engage the mag., focus, then half press the shutter to get back to the normal view and take picture. You don't have to cycle through the higher tier to get back to normal view.

If you're only using one tier of mag, why not activate the auto mag with focus ring and then use the shutter half press to get back to normal?

Yes, that makes sense. I have and loved using this lens for over a year now. Coming from Canon and being a back button shooter I set the C3 button on my A7ii to Magnify. Very easy to pump it once or twice as required. I shoot my dog playing ball and swimming quite a bit and have mostly got the hang of dim (dogs in motion). IBIS really helps as do your Creative Style settings. Don't forget to add a little gaffer tape to the diopter wheel so it doesn't move on you.

finally found in the menu: AF in Focus Mag. must be on off!
Now with half press on the shutter button I can magnify back to normal from first step magnify...

Did you inspect for dust when you first bought it? It's not uncommon for brand new lenses to have some dust particles inside.
I am just a hobbyist, but I have had numerous spots show up on sunsets and similar images. It has been sensor dust every single time, always resolved with a good solid blowing out with a rocket blower. I have one rather old lens that actually has a small insect carcass inside toward one edge, and I have yet to see it have an effect on an image. Going out on a limb here, but if all the other lenses you tested were vintage, perhaps the dust only shows on the CV because of the high resolution/IQ. (I have one and it is a great lens!)
Have you tried cleaning the sensor? You normally would not have to do a wet clean, just take a good rocket blower after it. You have nothing to lose and everything to gain by at least giving it a try.
