  • Overcast days provide the best light in my view. Your shots have an HDR quality or perhaps just low contrast, but I would be tempted to notch it  up  in your RAW software. My original G15 was ...
  • Very nice - a bit of CA, but the corners look good - did you crop the original at all ? I need to crop my Rokkor 17mm f4 down to about this focal length to get this kind of result on my A7
  • True Trioplan bubbles with the very thin bright outer ring are easier to get from triplets, but a triplet does not guarantee them . I had a Feinmess Bonatar which would not oblige. The non triplet ...
  • Interesting to note that a reply I gave earlier in this thread about the convenience of 3D TV as a viewing method having an obsolete feel has now come true ......... http://www.telegraph.co.uk/news ...
  • Despite the hype the Minolta is still an amazing bargain - my original copy was stolen and I replaced it at once. As mentioned, hardly any CA and always sharp. The original non macro version is ...
  • Nice shots - I have that Tamron too and find it tricky even with static subjects. I find Focus Peaking very unreliable with my A7 and use the magnification instead. Its a great lens, but very ...
  • Canon does make (or did ) a WA converter which uses the same tube attachment that allows the use of filters. These converters have a bad reputation, but I remember using an Olympus Wcon 08B some ...
  • Very nice shots. Sometimes a camera just feels right and hardly ever lets you down - thats what I thought of my G15. Unfortunately it was stolen and I could only replace it with the G16 - which ...
  • No question that the Fuji is the best 3D camera available, thats why its price is so high on the second hand market. The Lumix has only (I think) a 30cm interaxial, which makes it pretty useless ...
  • This is interesting to me in that it might explain why so many people find the movie 2D to 3D conversions so unconvincing and conversely why , frustratingly, so many people find "true" ...
  • Created discussion thread Cheap Trioplan.......Doubling a Triplet
    Noticing that the dreaded Domiplan gives nice Trioplan bubbles, but of reduced size, I cheated with a Komura Telemore 95 2x converter to try to get the bubbles bigger. It seems to work quite well, ...
  • I think for the full flavoured legacy glass experience you need FF.  APSC and MFT have really annoying crop factors however good the cameras may be and playing around with speed boosters or lens ...
  • I got the A7 to use with my old manual lenses and to be honest I have hardly used the kit lens that came with it. I dont think it is a bad lens at all and the autofocus is great - its just a bit ...
  • If we are we talking about the constant f3.5 macro version , then my copy is excellent too even on a FF Sony A7. For sure less contrast than kit zooms (but this might be boosted in camera for ...
  • After I checked here (and also follwed some of the links) : http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/glass.html I was surprised to find out that such large quantities of lead oxide were ...
  • All good advice so far I think , but what about about another "pancake" which is still a bargain - the Minolta MD 45mm f2. Can be had for very little, even with todays inflated Rokkor prices. It ...
  • None looks ouystanding - but I have some cheap legacy glass that constantly surprises me. I would repost to the Adapted Lens forum where knowledge about these things abounds and you are sure to get ...
  • I have this lens under the Rokinon name and reckon that for a Full Frame UWA it is a real bargain, but it takes a lot of getting used to. Focussing is critical wide open because of the field ...
  • Replied in Adapte-whaaaa?
    Samyang is the manufacturer, but they also supply other companies with the same lens, which is then rebranded as Rokinon, Bower etc. The prices can therefore vary for the same product. For example ...
  • Replied in Adapte-whaaaa?
    +1...............with the Samyang you will get an approximately 21mm wide angle. It will be quite big on your camera and you will need to practice a bit with the manual focus, but results in my ...
