  • Well it seems NOT to focus with the lens, but simply shifts the whole lens relative to the camera. Surely you would need to set an approximate focus on the lens first, then the device "fine tunes". ...
  • Thank you for leading me to that article - it seems that the UV light may have the same effect on the valence electrons as heating the glass to annealing temperatures. I think my lens is best left ...
  • I have a Canon FD 35mm f2 lens which has a yellow cast. Conventional wisdom is that it can be "cured" by exposure to UV light - even bright sunlight. Whilst I can accept that the Thorium decay ...
  • This link is better I think......time to get a new mouse. http://www.ebay.co.uk/itm/291636536929?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
  • Created discussion thread Multi-adapter ????
    I happened upon this on Ebay and it would seem to be a rather neat solution to the problem of having to buy an adapter for every different lens mount we use. Possibly too good to be true, but I ...
  • I used to get this view from my window, now that I have moved I have to climb onto my roof ! This was Popocatepetl´s last big eruption, taken with an old and battered Nikkor Q Auto 200mm f4 and ...
  • Thanks for the information. Mine has only has Micro - NIKKOR  55mm 1:3.5 around the barrel. It came with a PK3 extension tube which takes it to 1:1 I believe. Serial is 1033949, so the non AI ...
  • The Micro Nikkor 55mm f3.5 is the sharpest lens I have ever owned - at any focussing distance - and a relatively simple 5/4 design. I should use it more but I prefer a wider FOV....if I could only ...
  • Yes I do think there is some decentering , but overall the corners are not too bad. The quest for a good old uwa lens is definitely tricky. I have a 17mm Minolta (good reputation) and Cosina 19mm ...
  • No question that $100 can buy a very good prime; but it can also get you a classic zoom. How about the Nikkor 80 -200mm f4.5 (AI or AI-s) - best 80 -200 ever ? . Mine like many is VERY sloppy and ...
  • About 10 years ago, when I was working for the BBC, I talked to a cameraman who had been filming interviews with some of Hitchcock´s leading ladies. One insisted on certain lighting and provided ...
  • I dont know why, but Ive never been lucky with 35mm primes - in any mount. I have the 35mm F3.5 Takumar en route and am hoping it will be OK. Presently I have the Canon 35mm f2 (Thoriated) and a ...
  • Maybe its just me but has anybody else noticed how horrible some posted images look ? Is this just aggressive compression or a bad choice of image size ? Perhaps we could have a guide for image ...
  • Absolutely - the matched WA converter for the Fuji X100 and similar models shows very little image degradation. I once owned an enormous and very heavy Olympus WA converter which worked extremely ...
  • Yes it was and thats the danger of using these "legendary" lenses on FF - they show up every fault so clearly. Hard to know though to what extent the sensor stack issue is coming into play. The ...
  • Well the adapters work OK with other Minoltas and its just typical corner smear for a lens of that design from that era - just much more than I would have expected. Here is an example:
  • Created discussion thread Your most disappointing lens.
    Since members of the forum seem (mostly) to join in this type of thread in good spirit, here is another. Which of your lenses has dashed your expectations the most ? For me it was the Minolta 17mm ...
  • I have this lens - its name caught my eye - and when I discovered it was a triplet I of course thought it would be Trioplan like in its rendering. Well no luck with bubbles so far - I think ...
  • I dont think it is a problem, but the Minolta to Canon adapters all require a glass element to achieve infinity focus, so I would read the reviews carefully for each adapter and buy the best ...
  • Replied in Macro lenses
    To answer my own question in another thread - I think I would keep my Micro Nikkor 55mm f3.5. Unfailingly sharp at any distance
