  • There is no such thing as non returnable o Ebay. You can get a refund by simply complaining and asking for it. Actually returning the item is optional.  You have 90 days to do this.  It is a major ...
  • The issue is "Does the job" Fr e the job is on-line pictures of my family at events and travel photos which go into large format photobooks. For me a 1/2.3" sensor does the job. I carry a Fujifilm ...
  • For me it has been Nikon Ai and Canon FD and the Vivitar Soli Cats. I have a Nikon 180 F/2.8, the pre ED model and it is superb.  I also have the 85 F/2 which is very compact, even on a turbo ...
  • The best way  to get out of doing free stuff is to do it badly.  With portraits, that can be hurtful so I would limit it to spot changes. If a person has a temporary blemish,a lipstick smear, ...
  • Liquids and solvents are Ok but the wiping and rubbing can be a problem.  Cotton swabs on wood sticks are widely used in optic labs but I do not like using liquids on unless on a swab. There are ...
  • Except for Leica prisms, most reflective surfaces are aluminized, unless they are for infrared in which case they are gold coated. If done correctly, the aluminum takes on a an oxide layer that ...
  • I have had a Meade 1 meter f/10 and taken a few shots with it but the one I lusted for was a Vivitar Series 1 Solid cat since I had some dealings with the maer and the man who designed it.  I have ...
  • There is a fast variable zoom, the Angenieux 35 70 and their later 28 70mm f 2.5 to f/3.3. It is a vintage lens and it is very good and still commands a worth price. See http://eos-5d-markii.blogsp ...
  • Best depends on a lot of issues but I went for the SEL 1018 after spending a lot of time at http://3d-kraft.com/index.php?option=com_content&view=article&id=145:the-wide-shootout-touitsonycompariso ...
  • If in situ means in place and with available light and laminated the big problem may be glare obscuring part of the map. When i encounter this, not so much for maps, but for paintings and other ...
  • The Vivitar solid cat is not a single piece o f glass but a significant number of glass elements. It is very well corrected and not too expensive. They were made by a top US (Perkin Elmer ...
  • From other posts I have seen longer but Vivitar 800 f/11 sold cat is a solid candidate,   It came with and easily adapted T threaded mount but mn also has a Nikon mount. I has a solid tripod collar ...
  • The question is a bit ill posed. One camera would probably be my Nex 7.  Most of my travel shots are wide and I use the SEL1018 and I'd carry something else for high speed or longer reach. If it ...
  • I have done this but i have read that focal reducers do not improve exposure speed beyond f/1.0.  It will increase your field of view but from what i have read these seems to be no value in using ...
  • The Pany DMC ZS cameras have worked for us.  My wife uses ours (hers) mostly but I take on morning jogs and it always with us. We bought her first one because it had the best stabilization of the ...
  • I have been happy with my first generation Zhonghi Nikon and Canon Fd adapters.  Besides giving extra coverage and a one stop speed benefit, they keep your sensor covered when changing lenses. Ther ...
  • A very long time ago at the dawn of "Natural child birth" approach now in use in most maternity wards i brought my camera to take photos of our new born.  I had decided I was not going to take any ...
  • I am not sure I understand the questions, but I assume by far limit and near limit the OP was asking about distance to place in focus for the stack.  If so, the far limit is closest distance at ...
  • Mine is 50mm Canon 50mm f/1.8 FD.  It just will not mount in my FD to Nex adapter.  I only paid $15 for it so its not a loss except for the time I spent diddling with it and such a loss of time is ...
  • I see very little of this. The high end vintage lenses were reviewed by extant publications such as Modern Photography.  They are now much older so they are likely to have lost some contrast but ...
