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. \

Jerome

Zhong what follow focus do you use? Motorised? And yes we are working on different screws. You are allowed to tighten them a bit further. But if you use very high torque motors we advice to set in and out points

neilcain

Jerome

Please update here when new screws are available, I’m finding mine come loose very easily

SantaMonicaAnamorphic

Jerome @Zhong - could you guys share more info on how you’re using the XUME magnetic adapter. From what I have seen the magnetic part is on the filter and the filter tray on the lens is not magnetic. Is there a version where the filter tray / receiver is magnetic or is there a 62mm thread magnet that would go onto the back of the Aivascope 1.75x? Many thanks for any tips.

Jerome

SantaMonicaAnamorphic i will dig into this wednesday and will follow up

Jerome

neilcain yes we will put them in our webshop after the vacation of aivascope (late august)

graphab

neilcain you. can buy it on DIY shop

Sean_Conley

Hey, I just received my 1.75X Aivascope and I want to put a push on cap for the rear element. The thread diameter appears to be 62mm. Can anyone confirm if a 62mm or 63mm push on cap would work?

Kinoliker

Okay, forget if there are weird aberrations like distortion, does the 40mm vignette on opengate 36×24mm?

Jerome

Kinoliker 40mm pancake will not vignette when finishing in 2.39

Jerome

Hey eean,

this will def work. a push cap will work

Sean_Conley

Jerome Hey Jerome, which one? 62mm or 63m?

narimangafurov

I have an old rubber cover from some vintage object lying around. It fit perfectly

Jerome

narimangafurov sounds cool! so you have pictures?

Sean_Conley

narimangafurov Can you measure the size? The cap aren’t cheap so I don’t want to buy multiples.

Scott

Anyone use the 1.75 with red Komodo? Still trying to decide between the 1.5 and the 1.75

Jerome

Scott the most logical choice for komodo is 1.5x. Otherwise your loosing a lot of sensor real estate.

EvanBurns

Scott

These are all Aivascope 1.75x w/ Meike 50mm f/1.2 on the Komodo. I love lenses with bigger squeeze factors, but that’s just me.

Scott

Jerome Even with a focal reducer? I know stacking too many filters is bad. Hard to really know before testing.

vlfflq

Jerome

What is the Ivascope that is optimized for Bmpcc 6k pro? 1.5X or 1.75x ??

I’d like to buy one of the two.

Also, can you recommend the lenses that go into this composition? Not something expensive.

Jerome

EvanBurns looks amazing! Thank you for sharing!!

Jerome

Scott well if you prefer your lenses with a reducer and you are okay with that look, than stacking the aivascope will still yield great results. generally a reducer can add bloom and a bit of coma and barrel distortion. But if you think it looks fine without the reducer than it will look fine with the scope as well, is my opinion
