Why, f4 lenses are sharp wide open, that was your criteria.

People often make the mistake of judging lenses wide open, but the problem is that not all lenses have the same largest aperture.

Sometimes the best way to get a lens that's sharp at a particular aperture is to get a lens with a wider aperture than your desired one.

No, my criteria was fast and sharp.

I have had a LOT of 50s and near 50s.

Very few are what I would consider sharp wide open though it is relative and none of the cheaper ones I have had would be.

MAYBE used on your camera they would be ok as they are not using the worst part of the lenses.

The best by far for me is the FE Sony Zeiss 55 1.8 which IS sharp wide open but that is no help to you.

One cheapy that i had and really liked was the Nikon 50 1.8 AF (non D made in Japan version).

Maybe any of the Nikon 50 1.8s? would be a reasonable combination of cheap/sharp enough?

IF you could find one in your price range, the FD 50 1.2 L (not the non L) is sharp in the area in focus at 1.2 and it is better stopped down a little so still fast.

The same with the Pentax 50 1.2 I had though no asperic elements in the Pentax there is in the FD L (those two might be too dear though.

I ended up picking up a voigtlander 40mm f/1.4.
not 50mm but close enough.

Buy a 50mm F4 lens.  Virtually guaranteed to be sharp wide open.

That was literally no help at all.

I'm looking for a 28mm to use with my BMPCC 4k. It will be used sparingly for specific shots.
Main concern is center sharpness. Not too worried about edge sharpness.
What would you guys recommend.

thanks for taking the time, what camera taking lens and at what aperture did you shoot the test?

Here you go.

Does it go from minimum to infinity? Thanks!

Yes. If you have a single focus solution, then it will go from minimum to maximum.
I'll post some footage later, using it zooming from close range to infinity.

I need an adapater for my Jupiter 9. From M39 to MFT.

The only ones I can find are Leica M39 to MFT.

Yea, I'm talking about the telecine version withnthe recessed back lense. 

If you can get the rear set ring off, you can move the lens back. I was unable to do it. I think they used red loctite instead of blue. I've been able to heat blueloctite with a blow drier hot enough to loosen it up. I wasn't willing to risk heating the rear up enough to loosen the red loctit, and crack the lens.

I recently bought a Moller 32/2, with some front lens issues for cheap. 

I started looking for a donor front, and found one of the "Useless" telecine versions in immaculate shape.

The lens arrived, and I swapped out the front. Except the lense didn't line up properly from one barrel to the next. So I tried loosening the ring, to adjust the lense. I could not get it to budge. So I thought, great. Waste of money. I started to compare the lenses, and noticed that the only difference between the 2 was that the telecine version had the rear lense closer to the front lense.

I took it apart, removed the focusing guides, and started shifting the front lens forward, and suddenly it focused.

I had to modify the focusing guides. allowing for only one screw to be used to fasten it. But now it's razor sharp, and with a Single focus adapter, it can focus up to 16 inches.

The easiest thing would be to loosen the back retaining ring, remove the lense. Slip in some kind of spacer to get the rear lense all the way to the rear, nd scerw the retainer ring in.

Either way, that "Useless" version of Moller 32/2, is now completely useful.

You seem to be very focused on sharpness, but seem to be buying the wrong lenses for that.

If you're talking about using it on your P4K (like in the other thread) then maybe you should just invest in the Sigma 18-35 1.8 and Sigma 50-100 1.8 with a metabones SB and be done with it.  They're super sharp and will cover most of the range required.

If you're chasing sharpness wide open and also the softer contrast of vintage lenses then the Tiffen filters can give that look quite easily.

I hate the look of the Sigma 18-35. I had one.

I actually bought a voigtlander 40mm, it's awesome.

So, where's the best place in DaVinci to set the color science?

I'm sure you'll find an interested buyer there. And no ebay fees.

It just says 2x Anamorphic on it. 

Lens made in Japan

For Bell & Howell

Photo attached if that helps?

Thanks for any help!

The Bell and howell is the number one popular and most expensive Kowa.
I would list it on Ebay starting at around $900 if the glass is in great condition.

Sorry.

Using it with my Blackmagic pocket cinema camera 4k.

So, anything that is MFT or can adapt to it.

I am looking for a 50mm lens that's very sharp wide open.

I have a super takumar 50mm 1.4, but I need to stop it down to at least 2.8 to get it nice and sharp.

So what do you guys recommend for under $400.

Depends on the model..

Which Kowa is it?

When adjusting focus on my super takumar 50mm, the aperture slightly shifts. 

It juggles a bit, she I hold the body, svd move the front barrel. 

Can I fix this? 

So, I realised yesterday while working on the setup for my anamorphic lens on my BMPCC 4K, that THE passive L39 and m42 to mft adapters are off. 

When using an EF adapter, then a speedbooster, focus to Infinity was fine on the m42. 

When using the passive mft adapters, it was off. 

I printed 2 rings one for the m42 that was. 0.5mm thick. The other for my jupiter lens that is L39 to mft that is 0.02mm. 

Both focus great now.

Hi Guys,

I just started diving into the anamorphic world. Recently purchased B&H anamorphic lens. Came across this post with lot of valuable information to create the single focus solution. My lens didn't come with the backside series 7 adapter (silver) . What are the alternative available on eaby for replacement?

Thanks,

Dnyanesh

 

 

I have the ring with an S7 adapter to 58mm adapter if you're still interested 

Is there a way to tune the sharpness on these by opening them up like the Sankor and Kowas? 

I'd also like to flock the inside. 

Did a test. It's sharp, but does not flare as nice as my single focus Bell and Howell. 

So, it arrives today, and this thing is mint. Not a scratch anywhere.

It's identical to my Sankor 16C, but in much better condition. 

Going to do a flare and sharpness test later.

I think I have one, it has blue flare. Nothing special. Kinda small and light weight. If you find a cheap one, just buy it.

It was $250

I compared my Jupiter 8 to my Super takumar 50mm 1.4 and the Takumar is noticeably sharper.

I'm using the Jupiter 8 with an adapter on my BMPCC 4k. Is there an adjustment that might need to be made.
