  • Another approach, also used by astronomers who do not have the funds for adaptive optics is to stabilize the camera and take a large number of short exposures and then combine them taking the ...
  • Whatever spanner fame you use, teh essential element is a good fit of the tips into the slots. If you need to, file the tips to get a very crisp snug fit.
  • The old grades,  New, Like new, Ex, VG etc.   are well defined on KEH's web site.  Note they do not include "Mint" I trust these codes: 1) When used by a dealer 2) When used by a private seller ...
  • Yes I did, but I did miss that part, my bad. I still suggest that he try to remains a firefighter first and not take anything that distracts from staying alive.
  • I suggest a cold shower and a long think. Real forest fires are dangerous even, and especially to pros fighting the fires who know them a lot better than are likely to..  Many get killed by fires ...
  • The tent is a good start. Use as long a lens as possible and shoot from as far back as possible.  Jewelry is highly reflective and the closer you shot the larger the reflections of you and your ...
  • Reminds me of when I used to take a bag lunch. I was flying a lot so I used airline barf bags (unused!)  They were a good size, clean and had good closures.  Nobody took my lunch. For use in my car ...
  • Several travel good companies such as Magellan make bags and anti theft straps. My small bag is a Tumi black ballistic nylon messenger bag.   The leather Tumi bags are very recognizable but the ...
  • Travel dominates my usage.  My zoom is an SEL1018.  For everything else I use a superzoom small sensor camera.  I don't like changing lenses on the go, and I do not want to be too visible with ...
  • I have a an HS-30 so this may be wrong but it mine lets me zoom a bit.  I suspect the problem is that above a fairly short focal length the sweep rate is to fast for the stitching algorithm to work. ...
  • HI Lester, If mine is the post you referred to and its Adorama pix panorama books, thanks for your kind words; here is how to use the site. It is all done via access to their site via your browser. ...
  • I use Adoramapix lie flat panorama books.  Their quality is very good. We also use Blurb and they too do nice work. The Adoramapix allows a lot of freedom is sizing and cropping as well as adding ...
  • Thanks for the suggestions. It still does not work at any focus position. I cannot see and visible difference between the ones that mount and the f/1.8 50mm. What I can see is that this lens does ...
  • Created discussion thread Problem with Canon FD lens and adapter
    I recently acquired a 50mm F/2 (or is it 1.8?) Canon FD.  It will not lock on my turbo adapter.  I have a 135 f/2 FD and a 50mm f/3.5 FD macro that both work well. Any ideas?  I only have a few ...
  • Just a guess, but, sometimes these folders only focus when the bellows is fully out and engaged.  Be sure it is fully extended and locked in place
  • I use a Nex 7 with the Zhongyi turbo adapter. I have had interesting and sometimes useful results with the Sigma 14m F/3.5 in a Nikon mount. This is about as wide as I can get and it is wider than ...
  • The OP did not specify that the lens be fast so for a really shorp vintage lens at low cost I suggest either a Micro Nikkor 50mm f/3.5 or the competing Cannon FD macro 50 mm F/3.5 The 50 mm f/2 ...
  • I can't tell you which is best, so many criteria for various uses and I will never get to try the am all. For travel I suggest it is better not to buy top of the line flashy stuff.  Hasselblad ...
  • Kind of out of the box so get your rotten fruit ready but if you doing daylight and travel you do not pixel peeping detail, at least if you travel as I do.  We take several hundred photos per day ...
  • I have an ai 180 f/2.8 Nikkor which I use with a speed booster on an APS-C.  I read a lot about how the ED version is better but I have had sharpness that amazed me with this older lens.  There ...
