izzikiorage Posted September 10, 2017 Share Posted September 10, 2017 Hey Everyone, so I've been collecting legacy glass for a couple of years now. Wanted to figure out a good wide lens for my NEX6. the widest i have right now is my kit 16-50mm lens.

Username Posted September 10, 2017 Share Posted September 10, 2017 ` Legacy lenses are for 24x36mm format. Your camera is 16x24 format. The solution is a SpeedBooster, aka "focal reducer", aka "reverse tele-extender". You put something in the affordable 17 to 20mm range onto a SpeedBooster and you maintain 95% of the FoV plus lens speed at every stop is one stop faster. Ever notice that when you move a projector closer to a screen/wall to shrink the image size, that the image gets brighter and brighter, while getting smaller and smaller ? A SpeedBooster uses its optics, instead of a physical change of distance, to shrink the image that the lens is projecting toward the sensor ... but the principle of "smaller makes brighter" still pertains. Thaz how each f-stop becomes twice as bright. Due to the relay optics nature of SpeedBoosters, they are physically a few mm shorter than an ordinary non- optical [empty tube] adapter. Seems like a win-win, so there hasta be a catch, which is price :-( But, thaz the price. There's no really wide FoV legacy lens for APSC cuz, again, legacy lenses were made for a larger format. izzikiorage 1 Link to post Share on other sites More sharing options...
izzikiorage Posted September 11, 2017 Author Share Posted September 11, 2017 So something like a metabones is my only hope for getting a great wide angle Sent from my ONEPLUS A3003 using Tapatalk Link to post Share on other sites More sharing options...

So that means there is one other option. Perhaps that collection justifies acquiring an a7 or a7-II body. For my use, APSC has only the slightest advantage over FF, so the only reason I have one FF Sony [i have 4 APSC Sonys] is to make use of my pile of cool lenses left over from the film era. All film lenses [OK, 99.9% of them] are acoarst FF lenses. Initially I used my Nikkors on APSC Sonys via a SpeedBooster, and I still do that. But I also wanted to use all my old Minolta AF lenses and Sony has very appealing adapters for them, but they have no focal reducing optics in them, so to use the full FoV of those lenses you need a FF body ... even tho these adapters do function perfectly on the smaller bodies. ` izzikiorage 1 Link to post Share on other sites More sharing options...
izzikiorage Posted September 14, 2017 Author Share Posted September 14, 2017 That is the long term plan, as far as finances allow. The short term was to get hold of the widest lens available in the prime lenses, something that even with the 1.6X magnification factor would give awesome wide angle. The lowest I've found is 12mm lenses (19.2mm with crop factor), even of these i have no idea which ones are good Sent from my ONEPLUS A3003 using Tapatalk Link to post Share on other sites More sharing options...
miran Posted September 19, 2017 Share Posted September 19, 2017 Are you sure you have a Sony, not a Canon? Because Sony's APS-C crop factor is 1.5, Canon is 1.6. Anyway, adapting legacy wides is not such a good idea as modern lenses are just so much better. There's a very nice modern Samyang 12mm and it's affordable. It's sold under various different names around the world, you should look into that. If you're also not rectilinear wideangles, there are also a few fisheyes available. As far as I know you get the widest angle of view with the Meike 6.5mm which is a circular fisheye that can actually see slightly behind itself (190° diagonal).

Guest Jaf-Photo Posted September 19, 2017 Share Posted September 19, 2017 Like Miran, I would advise against adapting legacy wide angle lenses. Ultra wide lenses were difficult and expensive to manufacture until recent years. So the legacy ultra wide angle lenses are also rare, expensive and not very good. You seem to have been looking at the newer manual lenses with native E mount, like Samyang. That's probably your best bet. If you want better quality than the kitlens but not necessarily a wider field of view, then there are a few options like Sony 20 or Sigma 19. You could also look for a used copy of the Sony 10-18.

TeddyD Posted November 24, 2017 Share Posted November 24, 2017 Speaking of rectalinear glass I got Laowa 12mm f2.8, with focal reducer it's 8.5mm and works fine, just lean a bit forward to avoid your shoes in the picture. There's also Irix 11mm (7.8mm with focal reducer) which should be good thou I have not tried one. Viltrox makes a good focal reducer at fraction of the price of Metabones..

izzikiorage Posted January 14, 2018 Author Share Posted January 14, 2018 Wow, will find and compare these lenses. Might have to save up a bit, but if the new lenses are so much better then it'll be worth it Link to post Share on other sites More sharing options...
AntonioS Posted October 17, 2019 Share Posted October 17, 2019 I would go for a more modern design like the Rokinon 12mm F2 or the Laowa 9mm Zero-D Link to post Share on other sites More sharing options...
