Shooting and Recording exposure aperture data
Notice: please set up the adapter before use.
[See the How to Setup the Adapter section]
You can:
1. Set the maximum aperture on lens
2. Set the desired aperture on camera
3. Focus and meter the object, when focus is achieved, lock exposure setting.
4. Set the lens aperture to the same desired aperture as the camera setting
5. Press shutter button and take the picture.
And you can also:
1. Set the maximum aperture on lens
2. Set the aperture value on camera to maximum lens aperture
3. Focus and meter the object, when focus is achieved, lock exposure setting.
4. Set the lens aperture AND the camera aperture setting to the desired aperture.
5. Press shutter button and take the picture
Shooting and not recording exposure aperture setting
1. Set the aperture value on camera to the lens’ maximum aperture
2. Set the camera to AV mode
3. Set the desired aperture on lens
4. Focus and meter the object and take the picture.,
Exposure aperture data recorded in EXIF is the lens’ maximum aperture.
Step One
Enter Setting mode
1. Attach the adapter to your lens and attach the lens to your digital camera body and turn on the camera.
2. Set the camera in M mode and then set shutter speed to 1/60 second and aperture increment to 1/3 stop.
3. Set aperture to F/64 and press shutter button once.
4. Set aperture to F/57 and press shutter button once.
5. Set aperture to F/64 and press shutter button once.
Confirmation: turn the aperture setting dial on camera, if the aperture can be set to F/1.0, your adapter is now in Setting Mode.
Step Two
Set Focal Length And Maximum Aperture.
Set the focal length
Focal length can be set from 1 mm to 65535 mm. It is defined by five numbers. Numbers should be converted to aperture values before input into the adapter chip. Below is the number and aperture value conversion chart:
F2.0 F2.2 F2.5 F2.8 F3.2 F3.5 F4.0 F4.5 F5.0 F5.6
0 1 2 3 4 5 6 7 8 9
Turn the aperture setting dial and chose the right aperture value. And press shutter button to input the digit. Repeat this operation until all five digits are inputted.
If the focal length of your lens is smaller than five digits, you should add zeros before actual numbers.
For example, if you use a 50mm lens with the adapter, you should input 00050 (F2.0 shutter, F2.0 shutter, F2.0 shutter, F3.5 shutter, F2.0 shutter)
Finish Setting Focal Length
Set aperture to F/57 and press shutter button once
Set aperture to F/64 and press shutter button once
Set aperture to F/57 and press shutter button once
Maximum Aperture Setting
Turn the aperture dial and set the aperture to the maximum aperture of the lens.
Press shutter button once.
Notice:
Aperture should NOT be set to F/1.0. This setting is reserved for engineering purpose.
Aperture should be set higher than F/5.6 to avoid camera focus detecting system malfunction.
If all settings are inputted correctly, Lens data will be stored in your adapter.
If the aperture values are not chosen from above conversion chart during focal length input procedure, the adapter will automatically exit setting mode and data will not be stored in adapter.
The default lens data stored in the adapter is 50mm and F/1.2. You should change the data to fit your own lens’ specifications.
Attention:
Do not touch the golden contacts on the adapter circuit board with your fingers.
Do not use the F/64-F/57-F/64 aperture combination in normal operations. This combination will set the adapter in setting mode. If you unintentionally enters the setting mode, simply press shutter button once to exit.
Do not enter setting mode when camera is set at continuous shooting mode.
Do not set F/57 as the maximum aperture. This value is reserved for engineering purpose.
a latest update has been released, enable 32 steps AF adjustment on chip. Free samples for US and Europe will be available in two weeks when field test in china finished.

Thank you for the post Su (Su is how Big_IS signs his emails). The instructions are a more understandable English transaltion than the original instructions sent to me (although you should continue to refer to 1/3 exposure compensation as was done in the orginal instructions).
This new example (quoted just above) is excellent and would have saved me a couple of false starts.
I emailed your tech support ([email protected]) my concerns regarding why the max aperture should not remain selectable through the camera dial after the special programming is done & also how one can program the EXIF for the lens type being used example 35-70. As it stands, the resultant EXIF when using your new adapter indicates a lens named 1-65535mm.
RFK, Did you mean "remain selectable" or perhaps, "remain selected"? I believe it is selectable after the programming is done, right? I just want to clarify, as there may already be a mild translation problem from here to Hong Kong.
I think many would want it to remain selected (without the chance of being changed), to avoid mishaps with exposure, with the prime reason being that it is somewhat second nature for Canon users to move that aperture dial without even thinking about it too much, which would be a mistake in the case of the manual lens with this adapter.
I understand that Su is actually providing extra flexibility by allowing us to enter the actual f-stop and shutter into the EXIF, but if we get the wrong exposure too many times, it might not be worth it to have that extra flexibility. Maybe just and option to turn off that aperture movement on the camera (and leave it at the max aperture) would be best.
From what I'm gathering, this adapter is not malfunctioning, but rather has been programmed this way on purpose as an added feature (not speaking to RFK specifically).

Big_is sends a manual after one places the order. I can see why now. It is clear that the only aperture that should be programmed into the adapter is the lens' max aperture. Also, the programming steps are so voluminous IMO as to be wasting a lot of time as you say above. I am not sure I even understand the steps at this moment.
For anyone comptemplating this adapter, here are the programming steps:
For those of us who tend to dwell on the cynical side of things, what these new programmable chips really amount to is the transfer of the labor of programming from the vendor onto the user. The only advantage I see now for these types of adapter is if the user intends to use one adapter for several lenses (I buy one adapter for each of my lenses but that was when chipped adapters from happaypagehk were $50) or if the user sells the lens, he can use the adapter on the next lens he buys and change the coding. I'll probably return the Big_IS adapter and go with happypagehk since happypagehk can program in the lens "name" as 35-70. Can't be done on the Big_is adapters. If I am permitted, I will switch my item from a Contax to a Leica adapter as I have a Leica 35/2.8 I need a chipped adapter for and a single FL works fine on a prime....Show more →
I think you have missed the other feature that is superb! To be able to microadjust the actual adapter and lens combo without touching the camera microadjust( which from memory only works when you select a focal length that canon make when you try to set a lens in the camera microadjust)
If you don`t have a camera with microadjust you now have it with the new happy v5 adapter That must be worth the money , surely?
I learnt a long time ago that you fit an adapter to a lens(one you are happy with) and that`s where it stays, Changing lenses is bad enough out in the field let alone fiddling with adapters when it below zero more so.
When you get your happy v5 you will in a matter of minutes be flashing through the programme at will. It sounds complicated till you have the adapter in place and then once done it all falls in line.
With a bit of time set aside and a few varying distant targets I managed to get my contax lenses when the beep/light comes up to compare very well with live view (and thats at 10x with a hoodman loupe.)
As I wrote in a thread on the Canon forum, the 1dsmk3 is easier to get the focus dead on through the viewfinder because the 1 series responds better to a slow moving focus motion and you are better able to stop turning more or less dead on and provided you have microadjusted the adapter /lens combo you`ll find that checking with live view afterwards sees no improvement. The 5D2 needs a slightly faster focus action to bring in the beep/lights which sees you tending to have gone past the point and the need to flutter backwards and forwards a touch.
BTW I ordered on the Monday night, adapters sent on Tuesday and arrived no duty to pay on the Friday, well wrapped

I meant "remain selectable". That's why I referred to it as an accident waiting to happen in a post prior to the one you are responding to.
I should add here that the adapter I just receieved from Big_IS does not have the micro-adjustment feature. That is evident from the link I posted earlier to the Big_IS owner's manual but I feel I should mention it specifically to the forum at large in case there are some programmable but non-microadjust product left in Big_IS's inventory.

Can I assume that one could microadjust a lens so that the optimum focus at infinity occurs at the inifinity mark on the lens?
I have the 5D mkII and I've never actually set the microadjust for any lens. I've only played with it. The older happypagehk af-confirm adapters I have already for my best Contax & Leica lenses achieve perfect focus at the inifinity mark on the lens. I will not be tinkering with these.
However, the happypagehk adapter I have for the 35-70 and a couple of Zeiss ZF lenses have always been problematic. The adapter for the 35-70 doesn't lock down well, infinity focus rarely occurs at the infnity mark on the lens and occasionally I get a wildly incorrect & unexplainable exposure. The Nikon > EOS adapters for my Zeiss ZF achieve actual focus just prior to the infinity mark on the lens.
99% of my shooting with these particular lenses is at infinity. If I could get these lenses perfectly aligned to the infinity mark, assuming this is the purpose of microadjust, there would be less need for Live View and the subsequent battery drain (although I really do love Live View). I could use the viewfinder & Live View for composing mostly usually a less lengthy operation.
Rudolph has shipped my v5 adapter and programmed it as a 35-70 lens and at my request, went ahead and programmed my desired focal length and the max aperture. Yes, I am lazy.
Rudolph programmed the max aperture as f3.5 since this is the closest official Canon aperture. The 35-70 has an f3.4 max aperture. Apparently, on these programmable chips you can't just put anything in there you want willy nilly.

I`ll check but you might be right that a few max apertures might need to be to the nearest (3.4 for instance might have to be 3.5)
I still find that I have to set my exp comp to a minus with my contax lenses even with the V5 but like you probably do I watch the histo.

Always hard to tell exactly where inifinity is in the distance, it seems to be a long long way with some lenses.
One of my Contax lenses was bleeping just before infinity but adjusting the adapters micro adjust shifted it to infinity. I don`t use lens charts to adjust with, I always select various objects at various distances (which shows to me anyway) that there is a slight difference from a fairly close test chart to something 100Mtrs away.
I must admit that if I were to start using my f1.4 or f2 wide open I would probably find it hard to get all distances to fall in line but I am a landscape and grab shooter and usually stop down to at least f8 where most things fall in line( + a bit of common sense at times)

In general, infinity moves farther away as as the FL increases does it not? For example on my 21-28mm lenses, any distance from about 12 feet on out registers a beep/green dot when the lens is set to the infinity mark. I also verify the focus by looking at the image. This is true of my maual focus lenses as well as my canon lenses. 35mm is little further out and by 50mm, distances on some horizons do not register as infinity. I discovered this when testing/comparing the Zeiss 50 makro ZF to the Canon 50L f1.2 at my favorite lens testing location. Neither lens focused at the infinity mark. I surmised in this case that instead of having two faulty miscalibrated lenses, infinity was simply farther out than this particular horizon which was about two miles away.
Another example. I have multiple 35mm lenses and have tested all at the aforementioned location and all achieved infinity focus when focused on this horizon except my Zeiss 35 ZF. I still get brilliant images, but I'd like to have infinity focus on the mark. My reasoning: if infinity focus is at the mark which is also a stop, focusing in the field for many distances become a matter of simply keeping the focus ring turned to this stop basically turning the cam and manual focus lens into a P&S. So, I figure/hope this microadjust might help me get there. Well, it's my brilliant idea anyway.
The happypagehk adapter arrived yesterday and the adapter looks and feels like a quality product. The shipping was fast.
Unlike the previous adapter for my Contax 35-70, this adapter locks and stays locked into the mount.
It was already programmed for the max aperture and FL by Rudolph at my request. The only caveat here is that one must use f3.5 instead of f3.4. Don't know if this characteristic of having to match the Canon aperture nomeclature will always be an unchangeable "quirk" of the programmable chips, but I would prefer to see f3.4 in my EXIF.
The lens "name" 35-70 has been programmed in by Rudolph also unlike the Big_IS adapter.
The max aperture cannot be changed via the selection wheel or dial as is the case of Big_IS's adapter.
Instructions were included. Here are links to the various instruction manuals for the happypagehk programmable adapter in case anyone who is considering the purchase of one can get an advanced look at the programming involved. Sort of reminds me of how we had to program VCRs before they came with GUIs.
Should I get brave and attempt to "micro-adjust" this lens via the adapter, does anyone have a recommendation as to which FL I should use? I have several 35mm lenses so I would tend to use the 35-70 at the longer end. It seems reasonable to believe that using either 50mm or 70mm will provide enough range to benefit the other FL but I have never Micro-adjusted before so I am unfamiliar with the typical result.
I received an email from Big_IS today:
We have just completed a canon chip update. It does not only the exif self programming but also Stepping af adjustment(32 steps). Also, the olympus and sony AF adapter are updating. So we closed our ebay for a week. During
this time, we will update manual, pictures, and price. But we are still
hearing your voice, any question, please email us.
Regards
Su
I was kinda of hoping they would update Leica adapters too and offer me a free upgrade. Oh well.

I haven`t done my 35-70 but when I do I`ll probably opt for the 50mm centre position. Honestly! just get stuck into it, within a few minutes you`ll be swapping adjustments almost as quick as changing the cameras ISO I`d probably set it up for 50 and then have a look at the wide and tele ends to see how it fairs. You can always put it back to the default if things get out of hand.
I`m not that sure that the micro adjust is really meant for zooms, can`t remember the correct term now but some zooms stay focussed as you change focal lengths and some change focus. The ones that change focus might well be a problem.
The only time I tend to use a zoom over primes now days is when I need reach above 100mm and then I use the 70-200f4IS with the cameras own micro adjust.
Hard to say if the CZ 35-70 is, because of the 'one touch' zoom/focus action.. you can only really test it at infinity, provided your adapter is accurate at infinity
I'd say it's 'sort of' parfocal.. my adapter is pretty good at infinity and it 'seems' parfocal, but it's anyone's guess at a shorter focus distance
