Aivascope 1.75x update may 2022 : we have a few slots over for the batch of June 2022, get your copy a lot quicker by ordering now! email info @gafpagear.com or order directly https://gafpagear.com/product/aivascope-1-75x-anamorphic-adapter/ A small update for those who are awaiting the new Aivascope 1.75x . This weekend we were very honored to had Valdas Misevicius (Mr. Aivascope) and his daughter over at our office, all the way from Lithuania. They brought a few very cool and exciting lens projects. One of these lenses is the highly anticipated Aivascope 1.75x with an improved helicoid which we will also see in the December batch of Aivascope 1.5x . It has better grease leak protection compared to the current ones and an all new skew locking ring. The 1.75 is slightly bigger than the 1.5x and thus also a bit more heavy it features a 40mm rear element and we found it can cover a 50mm focal length in 36×24mm sensor dimension which gives a 2.63 aspect ratio without vignetting. The lens is amber coated with a few hints of magenta. Close focus is 80cm. Aivascope is planning to ship the first small batch to us in January, we are almost sold out on the 1.75x , if you want any info please reach out to info@gafpagear.com We plan to upload all specs and photos and footage shot with this adapter this week as a new entry to our shop. So keep an eye on our website. Have a great day!

Coverage / distortion here is the most ugly but also an important test.. bottlenecking the scope with a 50mm pancolar. and reveiling its distortion. All specs are in the video. As you can expect the most extreme thing you can do is do pans, with straight lines close to the camera (1.5m away is the window). Also as you can expect there is some anamorphic breathing going on, when going from infinity to close focus (80cm) > this is no sharpness test, zero contrast ratios (overcast), and a 50mm 1.9 wfo 🙂

flare Here we go, a quick nasty flare test! All specs in video title overlay.

a bit more info The Aivascope 1.75X has a slight improved helicoid and a protection against grease leakage, The latest generation of the 1.5X (gen4) has a 38mm rear optical element, and the 1.75X is even larger, featuring a 40mm rear element. The total weight of the 1.75X including the Rod support is 1.4Kg which is about 600 grams more than the 1.5X. Close focus is the same as the 1.5X namely 80cm, and we found that the scope is able to resolve a 50mm focal length on a 36X24 sensor which equals a 2.63 aspect ratio. When finalizing in 2.39 a shorter focal length would be possible. The 1.75X has a similar coating to the 1.5X which has predominantly amber and a hint of magenta. the front filter thread is 82mm The price of the Aivascope 1.75X will be 2300 euro ex vat, if you are within the EU and you can provide us with a VAT number we won’t add VAT to the invoice. If you buy outside the EU we won’t charge VAT by default.* *Please note that additional charges from customs can be in place if you live outside the EU send us an email for more info info@gafpagear.com

Here are a few stills with the 1.75X and a biotar 58mm set at 2.8. I also have set up a dropbox where you can download the tiffs, to examine them better, please only for your own examination, dont plant these pictures everywhere on the net 🙂 https://www.dropbox.com/sh/f07tcurcn5gm25v/AACIPUEHHYgV3w_enlLd8rWia?dl=0 they are just quickly snapped pixtures, and show you the barrel distortion of this lens quite nicely. Most of you will not go such wide, but it’s good to know whats possible. This was taken with a 36X 24 sensor, so leading to around 2.66 cinemascope aspect.

Hi Jerome, I would like to know the front filter thread size and front diameter size of the 1.75x. I’ve heard the price will be around the same as the 1.5x can you confirm this? And in comparison to a DIY anamorphic solution, such as a 16h + FM, what would be the pros/cons? Cheers! 🙂

Jerome please ignore my ignorance 🤦♂️

@ “Джером” # p503 nice! thank you for your overview!

Biometar 80mm in OG Biometar 80mm in 36X 24mm in open gate, not the sharpest taking lens, but a beautiful ‘ vintage ’ zeiss rendition.

NIKON pancake 50mm in 16X22mm okay now we saw the usual suspects, what about a sharp pancake in 16X22 mm image size. A nikon pancake 1.8 50mm multicoat (i have a edition that doesn’ t have blue green coat but magenta purple amber). set at f2.8. even though the MAVO edge has low rolling shutter, anamorphic will increase rolling shutter artefacts by the number of it squeeze ratio , in this case 1.75X. I love the 16X 22 mode in the mavo lf which will get you extremely close to native 2.39. I don’t like a 50m with 1.75X in open gate (36X 24mm), even though it works its too extreme aov for me, but if anyone wants to see proof, a pancake can cover without severe vignetting, shoot me a message here. IN this example, same light as in previous example, exact same grading. \

hello all, I’m very interested in the aivascope amber. if i have a speedbooster on komodo is it better to go 1.75x or 1.5x? i usually like to shoot on fast glass. thank you in advance

Sean_Conley

Has anyone figured out how to eliminate the image shift that happens when a focus motor is on the aivascope? The whole image moves slightly when the focus motor is engaged. This is what makes this setup unusable for professional work. I am shooting a feature next month and want to use this scope but I can’t seem to get rid of this happening. I’m using steel 15mm rods and everything is clamped down super tight. The taking lens is not screwed onto the rear to make the lens swaps quick on set.

Sean_Conley

Follow up question. Currently using this with the Nucleus Nano Motor but my 1st on this feature will want to use his Nucleus M motors. Are these motors set to Low Torque too powerful for the helicoid?

Jerome

Sean_Conley if you set manual in and out points there won’t be an issue.

Sean_Conley

Jerome I did a test and the Nucleus M motor works but the image shift is the main issue I can’t seem to find a solve for.

I’m not sure if others have this issue, but any time the motor turns for a focus pull the entire image shifts due to the helicoid moving around. It’s most noticeable on longer lenses, but still visible on wides as well.

Have you noticed this on yours and/or have you found a solution for this?

Sean_Conley

I just realized my helicoid is loose. This might be causing the shift. Does anyone know what the size of the 3 allen screws are around the helicoid?

Kinoliker

Jerome alright, would a 35mm lens work for a 36mm image circle?

graphab

Kinoliker 40mm is the limit

JakobWilliams

Any update on a potential violet 1.75x aivascope? Loving my violet 1.5x.

graphab

Hi i sell my aivascope 1,75x .(I prefer spherical lenses) very goosd state. You can make offer on this bid https://www.ebay.fr/itm/166782051643

Sean_Conley

Jerome Hey Jerome. Which Voigtlander Ultron do you have? The SL-II or SL-IIS? The SL-II would allow you to get closer to the Aivascope so I assume that is which one you are using but just curious. I am trying to decide between the two for anamorphic and for use on my FE2.

Jerome

Sean_Conley hey Sean , we have the Sl2 , they dont sell it anymore, but there are a few for sale, I have two copies, both quite minty, if you need one send us an email @ info@gafpagear.com
