<p>I still dont understand why optixpcb offers both versions. The one with hole i dont understand.<br> my m42-lenses all have M/A-ring. i also have p6/M42.<br> so lets compare both: <br> M/A: M/A-difference only working when pin is pushed. In Auto-aperture set-one can quickly switch to fully open.<br> The only "advantage" of that hole is leaving the spring untouched. permanent pressure could weaken it.<br> Just have found out that one of my two Vivitars M42 had oily blades and i can see how slow mechanisme is.<br> Super Takumar 50/1.4 was hardly ever on an adapter and wonderfully working.<br> So the hole in adapter has two advantages:<br> a) left in automode no pressure on spring<br> b) switching from M to A opens aperture quickly<br> So i will get one with hole.<br> Where is the advantage of having NO hole pin always pressed? accidental switch to A and fully open lens? </p>

<p>Optixpcb has m42-eos-adapter in two versions. one of them seems the have a hole to fit the pin.<br />one of them is: Black without width edged<br> But i only understand it for m42-cams where cams lever will hit that pin an close aperture.<br> it seems there are three different m42-versions. read somewhere but i cant remember details<br> Thanks</p>

<p>Recently i found a thread here where someone mentioned to have a solution how to adapt view-lenses to Mamiya-Press cams. But its hard to find it again... even over google.<br />I PM him but no reply yet received. Yes i am also in contact with anthony sansone but he is busy.<br />Thanks a lot</p>

<p>Yes i am in contact again. But he is hardly avaible, has no internet etc. often. Gave me hints about MUP, filmbacks, imagequality, focussing.<br />i have just tested-at least on the desk-using 35mm-film in 67/120/220 back in 220-setting. Its not flat.... no good idea probably. better using rb67/70 vaccum back on g-adapter, maybe 35mm possible there in 70mm cartridge. why not running 2x35mm if no other choice there....?</p>

<p>Only 67-72mm stepup-ring is matching 62.55mm thick lens-front.</p>

<p>maybe for smaller filmsize also larger apertures will perfectly work. first tests are promising but lens is not yet finished. we must add a special shorter camera tube to novoflex B to fit shorter than official 400mm lens. and lens-adapter also not yet ready.</p>

<p>i was shooting against the sun on 35mm cam. was terrible. had contax 180/2.8 is like day and night.<br> i had a discussion with someone which had to leave contax/Zeiss for nikon(i still have contax system and eos DSLR 1000D). he told under difficult light zeiss is better. but meanwhile nikon also has better lenses, so has sigma. <br />regarding vignetting. the speedier and longer the 35mm lens the better the chance it will cover 6x7 without light-fall of even fully open. ok at least in viewfinder....THE BOKEH FACTORY on FB is doing such conversions.<br> i compared 80mm/2.8 biometar with zeiss /C/Y)85mm/1.4(i also have 2.8) biometar is soft. precise tests will be done when optixpcb-adapter is in house. some old aspherical lens on APS-C: Wow even fully open!</p>

<p>Anthony Sansone-very busy actually-once promised 4x5-conversion of mamyia press. At least he replied some days ago. but we didnt discuss this theme. But other news. so be prepared for instant-news.<br />i am here to find a better alternative to one-lens polaroidconversions by option8(on FB). Yes he has also removable lens version for 600SE and 45-systems but only 127mm is coupled. other lenses from 90-150, also longer but not infinity working only via scale and groundglass. on 600SE-cam instant-backs are switchable: all three are working. pola100, instaxwide, sx70/impossible. polaroid 600SE-filmbacks possible with adapter(M for MUP)-G for RB67.</p>

<p>I can confirm that old apo-ronar 360/9 must have 54.5mm front thread. will measure said .5 pitch.<br> SN 57009827<br> i compared/ measured inner and outside dimensions where i had them(55mm filter) and from differences i have got 54.33mm for lens-thread.<br> since lens/filter got 54.83mm i added .17mm to both to get 55mm rsp 54.5mm! BINGO</p>

<p>Why not recommended?</p>

<p>Are there old data-sheets for these lenses? to confirm these 54.5 x .5 i could mount but barely rotate a stepup-adapter 55mm. which has .75 standard filter pitch. 54.39mm measured^.</p>

<p>I wonder if i can get filter-adapters 54.5mm.... and filter holder for the 360/9. maybe 54.5 to 58mm would we wise. on apo-gerogons 210 and 240 i have dual-lensshades 52 and 58mm. i could add 62mm and more....</p>

<p>Is his website down?</p>

<p>very good project. dont ever be influenced what people say. Film dead, 4x5 dead.<br />If you need more money think about spreading the informations. or ask people here to inform about places to do.<br />i often wondered, when i saw good ideas which were not backed why i didnt see them earlier elsewhere.</p>

<p>So for infinity work with 210, 240 and 360mm which of these are best APO-Ronar, Apo-Gerogon or Rodagon. I have also G-clarons, also 150mm. only 6x6-cam used maybe also with tilt-adapter. b+w film. For color-film MC apo-ronars would be better right?</p>

<p>http://www.bhphotovideo.com/FrameWork/charts/comp_metzflash_canon_2.html#note<br> 3101, 3101M3 and 3101M4 versions depending cameras.<br> e.g.<br> 3101 as of M3 - for E-TTL-function with 40 MZ-3i and 40 MZ-1i<br> 3101 M4 power shot pro 70 the only digital cam listed.<br> Where are the others? all the DSLRs?</p>

<p>E-TTL versus E-TLL II<br> http://www.photo.net/canon-eos-digital-camera-forum/00AW7n<br />interesting study also understand what chipped-adapters can do. maybe better for testing using EF-lens only.<br> with 380 EX and dandelion-adapter for manual lenses reflector will be zoomed. i wonder what will happen if no-chip-adapter is used.</p>

<p><strong>Type A-II cameras:</strong> There is a sub-group of Type A cameras which enables E-TTL II flash metering with EX-series Speedlites.<br />since 380EX is only E-TTL and not E-TTL II it seems not to work on 1000D(Type-A-II) anyway.<br />i could check with 50E since its made for it. n.b: highspeed-exposure times are working with 1000D and TTL also(within limits) but only on hotshoe. higher speed will reduce flashpower. further testings.</p>

<p>Here seems the best explenations: at least for speedlites<br />http://cpn.canon-europe.com/content/education/infobank/flash/speedlite_compatibility.do<br />my 1000D is AII-type, <br> <strong>Centre:</strong> Type A cameras have sensors in the viewfinder area that read both ambient and flash illumination. These sensors operate with EX-series Speedlites. The cameras also have flash sensors in the bottom of the camera body for A-TTL metering with EZ-series Speedlites.<br> Why the hell are they not listing B-type cameras?</p>

<p>here is one of the mentioned lists but not the leaflet from 1/94:<br> http://www.bhphotovideo.com/FrameWork/charts/comp_metzflash_canon.html<br> more here: interestingly he does not mention A-TTL only TTL:<br> interesting is mentioning of C.Fn.<br />http://www.p4pictures.com/2014/08/difference-e-ttl-ttl-canon-flash/<br> in my 1000D C.Fn III(no6) autofocus/transport i can set active, deactive and only active with external flash.<br> maybe when using manual lens one must set external flash option when flash on cable.<br> maybe flash-measuring is coupled with AF sort of A-TLL. SCA 3101-module has A-TTL off or on. </p>

<p>I meant using the external cable of canon on metz instead of 307A or 3007A. I could simulate SCA 300-system on Contax 139/137 MA since i have flashmeter. pity not contax RTS III anymore where flashmeter is build-in.</p>

<p>In SCA-30-list 1/94 not everything is clear. its too complicated to explain. one does not know which functions work for certain cam because they made unclear clamp for a cgroupd of cameras with different functions-combination. instead of just setting the blue points to where its working. What the hell were they thinking?<br> because of that i am unsure of EOS1(EOS1N) is working TTL with 311.<br> 312 AF only adds AF-metering-flash. but i will use manual lens. so 311 should do.<br> they say for 312 AF one needs distant piece SCA 300D with work oin 32 MZ-3, 40MZ-2, 32 CT 7 and 32 CT-8. to avoid colliding AF-beam with lens in my opinion.<br />i also have a combined instructions 300/3000(consulted seen some days ago) but i cant find right now. anyone seen online? german or english</p> <p> </p>

<p>Hello I am trying to find out why e-ttl is not working on 1000D when using SCA 3000 cable-system(3000A) with metz 32 MZ-3 and canon speedlite 380EX with chinese copy of cable 2(what the complete canon model-name?).<br /> maybe both cable are defective. or also 3101-adapter. Its also not working on Eos-1N<br /> I wonder of i need an adapter upgrade. my version is: 3101 M. Is there a list showing the versions for EOS?<br /> Must also study adapter-manual. among others it has a-ttl-setting(off and on-option). maybe my SCA-flash with 3101 can only A-TTL.<br /> i also have 3102 but flash is 3000-type not 3002.<br />Next will be getting original canon cable 2 and a new 3000A.<br /> SCA-flash is working properly with SCA 300-system using 311. 311 cannot be used with 1N. <br /> on hotshoe TTL seems to work. will test again.<br /> SCA-Manual says shortest exposure is 15% from largest distance. So i dont wonder why at 1m at 100iso aperture larger than f2.8 are not possible. maybe with more diffusion or ND. plastic-filters no good idea. i once used a nd-gelatine filter which burnt a bit...<br /> Background is adjusting roundflash-reflector(chinese copy) for TTL and closeups.<br /> I am using this german info-site about SCA-system:<br /> http://faq.d-r-f.de/wiki/Metz_SCA-FAQ<br />among another a list with flashes:<br /> metz mecablitz system sca 300/3000: welcher adapter passt zu ihrer kamera?<br /> which adapter is working with your camera<br> should be in first link<br> http://faq.d-r-f.de/w/images/4/46/SCA_300-D.pdf</p>
