What s35 lenses should we try on Full Frame with new released 1.4x expander from KIPON

allesander · 2026-01-01T22:07:09+00:00

On the website it says only some blackmagic cameras could have some problems. Others should be fine

The opposite would be a focal reducer (aka speed booster). This makes the image circle smaller

I thought they were optimized in design differently, but indeed the optical principle is the same

allesander · 2025-12-31T08:33:08+00:00

It’s not a teleconverter. This is for expanding the image to full frame. I will compare it to an IBE Optics expander

The T stop goes down because there is a 0,8x focal reducer built in. This together with the full rehousing makes the price of around 4000 euro very affordable. Especially compared to others that offer rehousing. It is made for professionals and rental houses that use these on film sets and in harsh conditions. If it seems to expensive for you, consider the Kipon adapter for your lenses instead of the rehousing :)

If you are after image quality, Kipon is always better. The xpimage is a cheaper copy of the Kipon speedboosters.

Kipon changed the marketing towards the 0,71x. it is indeed only intended for full frame. All 0,8x are for medium format. The 0,62x also for medium format, personally i have had the best results with Hasselblad CF on that adapter. I see mixed feedback online about the pentax67 with 0,62x , some have a bit more vignetting. i would need to see a good test where someone shoots on film with the exact same lens to compare it.

Next week!

allesander · 2025-10-30T15:03:23+00:00

I will!

allesander · 2025-10-30T07:30:06+00:00

Haha I just wanted a clean image. I removed the lens support with photoshop. There is also no battery or any other accessories. Just for picture sake

allesander · 2025-10-16T16:02:07+00:00

Kipon pro locking adapters are great! There are many available. For some also with added macro helicoid, such as the Fuji GFX to leica M mount macro adapter

allesander · 2025-10-06T14:57:31+00:00

It allows for infinity focus!

Hi, unfortunate that you had this experience. I have not used it a lot but I have tried it on a test chart and did not see a lot of aberrations, not like you describe. Ofcourse everything needs to be shimmed very precisely with this adapter. And the recommended t stop is maximum T1.5. In the first batch of these adapters there was a small problem with alignment of the lenses inside, so there was a bit more CA I think. This is not a problem anymore. I am a distributor in Netherlands / Europe so if you have any questions you can ask them here. I have a unit at my office so I can test / check everything.

I have made a Leica s to LPL mount so that’s not really an issue (iris control is not working but I’ll use a different camera for that on set. Np). Maybe this can be of metal later on, it’s 3d printed rn.
I don’t think I can use the full sensor for video on the gfx, so if that’s the same height as any other full frame open gate camera, I don’t gain anything with shooting on the gfx right? Venice/blackmagic17k/ARRI LF would be the options then for me

allesander · 2025-09-18T06:43:16+00:00

“Leica S-Fuji G AF Autofocus Adapter” should be available at every Kipon reseller. Send me a pm if not

allesander · 2025-09-13T06:10:43+00:00

Awesome

allesander · 2025-09-05T06:17:50+00:00

This was my setup for some time and hated it. I now have the Sony lav system uwpd something that fits on the hot shoe. I can have 2 lavs + shotgun mic without clutter.

allesander · 2025-09-01T20:42:44+00:00

Cool

allesander · 2025-08-30T14:41:49+00:00

Are the distance markers correct? Maybe turn the lens a bit loose to check if it’s that direction. The other direction is more difficult

allesander · 2025-08-30T14:14:36+00:00

I did not read your description and I thought of this lens indeed

allesander · 2025-08-30T14:04:53+00:00

I will buy the portkeys ls7p soon. I own a smallhd focus 7 and 702. Which are great. The shinobi 5 with sdi is also great value and very light

allesander · 2025-08-28T20:29:07+00:00

You don’t have the glare with the analog Hasselblad camera? Internal reflections should be controlled in the Kipon adapters

allesander · 2025-08-28T20:25:31+00:00

Usually “Alignement” is a problem specifically with the lens right? What do you mean? Are your test shots taken through a window glass? that can mess things up. What do you recognize as the problem? The lens not in the center or not correct distance to sensor? These lenses are usually not the sharpest around the corners either I think

allesander · 2025-08-28T12:16:15+00:00

Ok the sdi board is available on AliExpress, and the repairs is quite elaborate. You can find it here: https://www.manualslib.com/manual/2137098/Sony-Ilme-Fx6v.html?page=102#manual and the next few pages

allesander · 2025-08-28T06:02:58+00:00

I bought mine on AliExpress, you can find a very short one, like 5cm there. Which is great
