    At this rate of pro feature adoption by mobile phones, I'm starting to wonder if Canon should start making pro lenses for mobile phones instead of focusing on point and shoots...

    Julian reacted to Gábor Ember in The Diopter Thread.   
    Well sort of. It needs to be mounted on the back lens group and move together with it. It can be done on telephoto lenses that have room at the back of the lens (check out the back of a Jupiter-37A, you could easily fit a Helios back lens group in there), otherwise the focal reducer hits the mirror. Would be good to own a mirrorless cam. That way I would not need a negative diopter, I could move the whole lens closer to the sensor.

    Julian reacted to Gábor Ember in The Diopter Thread.   
    Are there any negative diopters? I mean usually they are useless but does anyone know about them being produced for photography? I used the back glass group of a Helios as a focal reducer successfully but it reduces the working distance and I want to counteract this by using a negative diopter.
    I haven't used this for anamorphic yet, but I thought I ask this here.

    Julian got a reaction from nahua in Samyang lenses with speedbooster. Good idea?   
    Welcome to the SpeedBooster :)
     
    If you have a 35mm 1.4 and a speedbooster, buying a 24mm 1.4 is pointless indeed (unless you want to use it on the speed booster, as 17mm f/1.0.
     
    Normal adapters don't give any quality loss. They just extend the mount. Optically the Samyang lenses are all the same. The ones with MFT mount just are longer with a different mount, so you don't need the adapter.
     
    Buying the Nikon versions with a Speedbooster is a good idea. Results with the SB can vary from lens to lens, so you might want to check out other peoples results with the Samyang lenses on the SB, although I don't see any reason for trouble. Just have a look on Vimeo and you'll find good results.
     
    The only doubt is the Samyang 16mm f/2.0 - it's made for aps-c-sensors with a crop factor of 1.5x
    With the SpeedBooster your GH3 will have a crop factor of 2x 0,71 = 1,42x, so you'll be pushing the 16mm a bit 'over the edge'. Most lenses have an image circle that is bigger than what they are designed for, I think it will work without problems, especially since you're in a 16:9 crop for video. But best thing would be to try before you buy.

    I've shot with the A7 for a full day, you can see the video here:

    Looking at the image afterwards though, I'm not as excited as I initially was.  I loved the process of shooting with the camera, but the image quality is pretty wanting.  As you can see on the video above, the image is quite soft, and moire is visible in many shots.  Hopefully, this can be chalked up to pre-release firmware, but we permitted to judge the video quality based on the models we had, and I'm not delighted with the results.  Once the production cameras come out, I'll post a follow up to the above video with my revised opinions.

    both lens will be good but they will not be cemented corrected doublets.

    they are simple single element optics with an airgap.

    Julian reacted to eris in future proof Manual Focus lenses for BMPCC & M43 BMCC   
    Take the following recommendations with a grain of salt.  I started out self-financing my own film career, so a whole set of L-glass was out o the picture.
     
    I've thought of going to the BMPCC, but as attractive as the camera is physically including raw and 422, the odds that lower priced m43 and APS-C (semi-super-35) sensors will begin providing raw and 422 out of the box are good.
     
    I've already tried competing with others for the rare old glass.  For example, really good examples of anamorphic glass (without even single focus) such as the Bolex Moeller 16/32 are going for over $2000.   That's just crazy when you can rent a set of Oct 19/P2 Lomo's for 2 weeks for $2000.
     
    At some point you realize you just have to pay a little extra to get what you want now and move on.  The BMCC is getting discounted to a reasonable price.  Get one (if you can) for M43.
     
    (Really wish some company would take a Bolex Moller 16/32 to an optical engineer and just copy the design -- except include focus servos for those that want single focus as an option.)
     
    As far as your other questions: My experience has taught me to buy the lenses and fit the right camera to them.   The half life of a decent digital camera these days is a about 2 years.   Good lenses last for a lifetime.   I'm still running with my set of manual DSLR lenses plus a Tokina 11-16 and a Minolta Macro Zoom for special occasions.  I'm betting on micro 4/3 and larger sensors in the future.  For what it's worth, here's my current lens list:
     
    Pentax/Asahi:
     
    Super-Multi-Coated Takumar 35mm f2  
    Super-Multi-Coated Takumar 50mm f1.4
    Super Takumar 50mm f1.4 (first production series)
     
    All the Takumars are super high precision, buttery focus, have generally excellent bokeh and are inexpensive.  Huge bang for the buck.  The 35mm gives a relatively normal field of view for crop sensors and the 50 becomes nice for short portaits.   Good for multitude of purposes.  The first gen Super Tak is beautiful and very nice as an anamorphic taking lens.  It's not too wide and it's single coated so it doesn't filter anamorphic flare.
     
    Minolta:
     
    Rokkor-PG 58mm f1.2
    Rokkor Zoom Macro 35-70mm
     
    The right Minolta manual can be very useful.  We shot a lot of our first film on the f1.2 Rokkor.  On a crop sensor it becomes an almost magical short portrait lens, isn't too "analytical" and yields just gorgeous natural light results with the best bokeh in the business.  Sort of a legendary bokeh monster lens.  Just be prepared for razor thin DOF at f1.2.  Don't overuse the f1.2 in natural light *instead* of proper lighting.
     
    The Rokkor Zoom Macro is a incredibly precise Zoom that rivals most primes.  On crop sensors it covers short portrait to normal telephoto.   It has a 1.5x light macro mode that allows very close focus which is great for super-closeups (rare in a zoom).  This is the lens that Leica liked so much they re-badged it as their own.  If you wait a week or so on ebay you can usually find a nice example that not too expensive.  I think I got mine for $200.
     
    Zeiss Jena:
     
    35mm f2.4 Flektogon
    80mm f2.8 Biometar Zebra (Medium Format)
     
    Zeiss Jena is the original Zeiss factory that the Russians captured and move to the homelad after WWII (which resulted in the Helios 44-2 and others). When Jena recovered they continued making mostly comparable glass into the 60s and early 70s until the warped communist economy finally screwed up their production capabilities.
     
    The 35mm f2.4 Flektogon is a wonderful little lens.  It's precise, not too large, has a normal field of view for crop sensors and great bokeh.  Oh yeah -- it has the standard Zeiss mechanical and optical precision and punchy contrast.   It also focuses down to 3 inches. :-)
     
    The 80mm Biometar is an interesting lens.  I found it while searching for a good long focal length anamorphic taking lens.  It had to have single coating so as not to unduly filter out anamorphic flare (thus the 1960s Zebra version).  It had to have good precision and optics.   It's Zeiss Jena and the overall optical quality is only slightly less than the equivalent West German Zeiss of the time.  In any case its optical performance in the center is second to none and that's what the m43 and APS-C sensors are going to be looking through.   I have noticed *no* aberations when looking through the center -- first time I've heard that.   Any imperfections in the center would either be eliminated by Zeiss QC or not generally in the field of focus.
     
    The wierd thing is (not sure how this works) is that while it's rated at f2.8, it lets almost as much light through at f2.8 as my f1.4 takumars -- but without the accompanying razor thin DOF.   Early anamorphic tests are very positive with LED point sources throwing super punchy and sharp anamorphic flare (right out of Alien :-), while the increased focal length and DOF makes for some very nice cinematic footage.  Mechanical design is typical Zeiss precision, but the Zebra Biometars are now almost 50 years old and the focus helical can get a little stiff.  Suggest you have it serviced at a reputable rebuilder for best performance.  These were the default lens on the old Pentacon Six cameras so there are a fair number of good examples left.   Expect to pay around $200 for a good copy.
     
    Nikon: Ai-s 24mm f2
     
    The Nikon used to be my go-to lens for slightly wider FOV with crop sensors.  Typical Nikon quality but I don't use it as much as I used to.  If I need to go wide-wide I usually use the excellent Tokina 11-16mm.
     
    Helios: 44-2 58mm f2
     
    The Helios is a Russian copy of the Zeiss Biotar.   It's used a lot as an anamorphic taking lens.  While it is single coated and a generally nice lens (fun bokeh, good flare, moderately precise), my copy (new old stock) had oil on the aperture blades and a pretty stiff focus ring.  There are rebuild videos by a cool Austrian dude on YouTube.  I might get around to it or just buy another.
     
    Sankor 16-D 2x Anamorphic
     
    Entry level, but beautiful Anamorphic.   My copy was in prettty fine physical shape.   I shot some fun test footage in Boulder CO on Pearl St Mall which I'll hopefully post some time soon.  The Sankor may not be the most precise anamorphic but it does throw beautiful anamorphic flares.  Good for understanding how anamorphics work even though it's dual focus.  You can get one for about $200 - $300 and pick up an adapter for about $50 - $100.   My only major issue is that, even though I swear I have it properly aligned, It's bokeh are oval but tilted slightly to the left and I can't figure out why.   It probably needs re-collimation, but I'm just guessing.
     
    Tokina 11-16mm f/2.8 AT-X Autofocus (either Nikon or Canon mount)
     
    This is a great constant focal length uber-wide zoom.  I recommend the Nikon mount for anything other than Canon as the Canon version doesn't have an easy way to manually adjust aperture.  Mines a canon mount and I just set and leave it at f2.8.  On a 2x crop the 11mm is still pretty wide.  Not sure how useful it would be adapted to a BMPCC.   It would be somewhere around 33mm which is wide, but not Quentin Tarantino wide (usually 24-28mm).  I bought this new at B&H for around $700 when it was hard to get.  My most expensive lens so far and I know that's not saying much.
     
    All in all I love my lens collection. 
     
    Good luck to you.

    Julian reacted to Sean Cunningham in Panavision's discovery for The World's End (Sept. ACM)   
    All of Edgar Wright's films have had impressive or, at the very least, quite pleasing and slick cinematography and his most recent installment to his and Simon Pegg's "Cornetto Trilogy", The World's End, is no exception.  There's a great feature article covering the style and technical approach to the film in the September issue of American Cinematographer Magazine (http://www.theasc.com/ac_magazine/September2013/current.php).
     
    When it got to the lens selection for the anamorphic portions of the film (once the scifi madness kicks in) I wasn't at all surprised that Wright and his DP went for a classic sampling that included C-Series lenses for their greater character versus new cinema anamorphics.  Wright likes to shine lights into the lens as much as anyone here (and he does it so much better than JJ Abrams).  Coincidentally, Panavision made a discovery at their Woodland Hills location, a B-Series that Panavision had failed to catalog and been long forgotten. 
     
     
    Given the way a lot of discussions go around here over this anamorphic or that anamorphic, I had to smile when I read the part where this DP praises aberration and soft edges.  
     
     
     
     
    ...and I always like when they go into this sort of detail, about working or target stops used on a film.  Anyway, it's a nicely detailed story about a contemporary anamorphic film that's worth grabbing an issue for.  
     
    Only God Forgives is likewise covered in this issue, and though it's not anamorphic it is, very surprisingly, a mostly practicals show with very few cinema lights used.  Having seen the film it's almost too hard to believe the information in the article.

    The 256 GB ExtremePro card that was just announced is the conventional CF type not CFast so those read/write times are not reflective of the new CFast cards.
     
    So unfortunately, while it is good to dream that you will get great raw video framerates with such cards.  The hardware is not compatible with the 5d3.
