  1. The way Nikon handled the PR around the proresRaw update is so poor. I can understand that they were trying to generate some hype but still... Imagine they had announced proresRaw just now. People would praise them up to heaven. And bitching about a paid upgrade? I mean we don't know what it costs, but if it's in the GH5/V-log league, who would have cared?

    Now people feel as if Nikon is breaking promises or giving them a bad deal.

    They need to get this update out ASAP.

  2. At it's current pricing, the Z6 -is- a steal, if you regard it as a true hybrid (for photography use too, try that on a BMPCC4K). But yes, native lens options are limited...I don't mind as I am very much enjoying all my vintage glass in conjunction with the fabulous Vizelex ND mount adapter.

    I think user adoption would be greatly accelerated if third party lens developers got on board.
    The E-mount Tamron zooms and Samyang AF primes are killing it on the Sonys.
    Imagine that whole portfolio being available for the Z-mount (or Canon RF for that matter).

  3. Man, German pricing is wild.
    A Z6, FTZ adapter, 24-70 F4 and that wonderful 50 F1.8 combined for less than 2500 euro.
    Or leave the FTZ adapter and end up below 2400...

    I was looking for a lightweight hybrid (Lumix S1 therefore no option). No way I am gonna support cripplin' Canon. So it went between the a7iii and the Z6...
    Seeing the nikon AF improve so drastically after the last firmware, with the promised external RAW and now this epic discount: count me in as a first time Nikon owner.

    Now to hoping the small Samyang AF primes don't take too long...

  4. Welcome Aaron! An additional diopter can still be helpful then, to further decrease the minimum focus distance of the variable diopter (obviously you lose infinity then, and you will have to account for possible vignetting). Which strength is useful depends on what you're shooting, but as the Rangefinder already goes to about 1m, I'd try a cheap +1 first for (extreme) close ups. You then have a broad range covered.

  5. This guy's style is a bit of an acquired taste, but he has a good nuanced take imo...the headphone jack, VlogL, unlimited recording, 120fps HD, assumably better AF and (for photography) 20MP make this a good upgrade, and especially for video shooters. A definitive G80 replacement? Nah. A great contender in the midprice range? Sure. And wait a few months and the price will be better (...and the G80 is now gonna be a REAL steal very soon).

    That's a gutsy disassembly! You said they were almost the same size, how did you make up the difference?

    It's actually relatively easy as there are only two elements that are each fixed with one retainer ring.

    The rear element can be swapped out, and the Rangefinder's back retainer ring can be re-used.

    On the front, the element of the Fujinon is a tad smaller and thinner. However, when using the Fujinon's original front retainer ring it grips perfectly, as that also has a 82mm outer thread, and it has a 'rim' that fits snugly over the element's edge.

    Only aspect that needs some tinkering is finding adequate spacers to lay the front element on. Otherwise it ends up to 'deep' in the housing. I used step rings, which work just fine.

    - SLR Magic Rangefinder hack -

    I was getting a bit tired of the blue blobbin' and bleeding flares of the SLR Magic Rangefinder. With the modified Century Optics wide-angle adapters being used for single focus rehousings (by POOLi™) I started thinking of using similar glass as replacement into the otherwise fine Rangefinder helicoid. One 0.82x wide-angle adapter seemed very close in dimensions: the Fujinon WCV-82SC, also sold as RCV-82SC, and also sold under the JVC brand. Note the 82mm front thread, which is the same as the RF.

    Found one cheap, disassembled it and sure enough, the two elements are very close in size to those found in the RF.

    • Rear element was easily replaced because it fits just fine, using the retainer ring on the back of the RF. But be very sure to put it in the right direction, very important!
    • Front element was a bit more tricky as it is somewhat thinner than the RF front element, ending up 'too deep' in the helicoid. Now it focused way past infinity and not close. So I used some step rings to lay the front element on and bring it more forward.
    • I then used the original retainer ring from the WA adapter to fix the front element in the helicoid. Tadaa...a new single focus in an old housing.

    Pro's:
    - wider shots possible
    - no more blue bleeding flares
    - close focus is a bit better also, I measured around 90cm, compared to listed MFD of the Rangefinder of 110cm.

    Cons:
    - somewhat more distortion at the edges and more CA
    - less sharp than RF in corners, but when using 2x anamorphics this is somewhat mitigated as the sharp center gets stretched out.
    - requires some fiddling with step rings behind the front element as spacer to calibrate focus range.

    Cheers, Tim

    P.S. You can find some (boring) test shots in the Facebook post.

    I’ve never heard of anyone using a 40mm on fullframe with projection anamorphics, but if I’m wrong someone should speak up.

    On the Anamorphic Shooters group on FB there was a guy that modified the Pentax 40mm 2.8 pancake to be even more flat at the front. He combined that with a Kowa 8z/16h/B&H (one of those) on a Canon 5diii with ML... Crazy bent edges though, so prolly not that useable. If I remember correctly there also wasn't a single focus attached.

    It will vignette at the EXACT SAME field of view no matter what size sensor you use. 

    The change in useable focal length (in mm) on various sensor sizes in indeed due to “equivalency”, also referrers to as “crop factor.” 

    I think we fully agree ?

    And in order to get to that exact same FOV on different sensor sizes, you will need equivalent lenses (50 on FF or 25 on m4/3 = same FOV).

    Cool. So here is my question then: would this m4/3 + X0.71 speed booster combo allow for being able to go to wider focal lengths before vignetting when paired with FF lenses??

    In other words, does this crop mode and focal reducer method solve the problem of the typical FF lens/FF sensor combo that can't go wider than 40-50mm lenses when using 2x scopes?  

    I'd like to get down to 25mm focal length lenses to use and so I'm trying to find a method to get out of the larger FF sensor sizes (which is causing the problem) while not going smaller than traditional 35mm film. All these ana scopes were made for this format after all...

    Your question is kind of confusing... I think the age old confusing topic of  'equivalency' might play a part here?

    Anyways...generally speaking the widest I have seen people get is somewhere in between 45-50mm fullframe equivalent focal lengths...

    Working with your proposed setup of a m43 sensor (crop factor 2) and 0.71 speedbooster, you end up with a final cropfactor of 2*0.71= 1.42 for the combination.

    Calculating with 50mm then gives 50/1.42=35.2 meaning that on m43 with 0.71x speedbooster the widest taking lens will be around 35mm.
    Working without speedbooster means you can use a 25mm focal length on M43 (as it translates to a 50mm equivalent FOV).

    Hope this helps.

    Thats the one....... The red dot is part of the alignement mechanism (how you adjust the alignment of the anamorphot) However that whole black plastic bottom part is removable. It's best to remove that and get a clamp so you can align it properly. This is a video I uploaded tonight all shot on the Ikon and Helios 44/2 as the taking lens........ 

     

    Its nothing special just a journey home from work I shot the other night. I've been so busy I've not really shot much with it. There's not much info on this lens though so thought I would upload something. If anyone has any questions about it I'm happy to answer.

    Nice vintage look. All shot wide open? Does it get sharper closing down? How is the focusing to handle?
