  • Before returning it I suggest that you try it. Repairing or refurbishing lenses is time consuming and if the service was successful they deserve to be paid. The point of the service is to restore ...
  • I replaced my HS-10 with an HS-30 now the HS-35. I miss the AA batteries and the very high speed video, which I did use from time to time.  The 35 still has 360 FPS video and it processes sweep ...
  • I have the 10-18.  This site convinced me that it was the way to go. When you have to look as hard as you do to see the difference it is not worth it at least for me. Also the 10-18 is stabilized ...
  • As others wrote, most vintage zooms are pretty bad.  The good ones are very pricey and so it is probably better to spend a bit more and get a lens made for the camera and get autofocus and ...
  • I have a 105mm f/4 micro Nikkor I have not sold because it is not worth enough to put on ebay. The ones there seem to go for well under $150. I'd add another $30 or so for the PK-3 27.5 mm ...
  • The first macro lenses were manual focus and the macros were among the least to get autofocus revisions.  The answer to your question is that it depends on how legacy. There are a lot of manual ...
  • I do most of my macro shooting with a superzoom and find autofocus works about half of the time.  I shoot details of watch mechanisms and I usually manually focus.  The parts I want in focus are ...
  • If it were uninhabited and I could only bring a camera it would be an interchangeable lens camera with a huge fast lens. The camera would be fun to play with but I could remove the lens and use it ...
  • Some situations demand it 1) Shooting through a window with rain drops on it.  Auto focus locks up on the raindrops.  It did with both cameras I had a Superzoom and a mirrorless.  I wanted the ...
  • If reputable lens I suggest you go for it but understand that you have at best 1) A 90 day warrantee 2) you may pay more for it than from a fixed price sale. Ebay now offers 90 day to return any ...
  • Obsession no but deep appreciation yes. Coupled rangefinders do more than scale focus.  In the hands of a skilled user they are good for tacking a moving subject and let you compose focus and shoot ...
  • Replied in Do you burst?
    I use it a lot for a technical application. I use it measure the time for a pendulum clock.  The pendulum swings about twice per second.  I want to catch the instant the seconds hand starts to move. ...
  • I do night shots with a superzoom. I find the "trick" is to support the camera, tripod, railing building etc and shoot in manual mode.  A rigid support like a railing works best  The IQ on my ...
  • Excuse my butting in but for very long reach the superzoom quality is usually as good as it gets.  True 700 to 1000mm lenses are not cheap unless you go the mirror route.  BTW there is a nice ...
  • I can't presume best but you might look for a 400mm Novoflex F/5.6 follow focus.  This is a modular system from the 1960's and on that has a precision pistol grip that you squeeze to focus. It is ...
  • Replied in Many types
    Not quite right. The Maksutov design was a brilliant solution to the problem that folded mirror lenses, Cassegrains,  require a complex aspherical shape to produce good optical performance.  The ...
  • I often try for them in churches, usually disappointing. Here is a better than my usual. Sweep panorama
  • One of the original uses was for spying.  The lens is very compact and can have a log focal lenth, while it can be made to look like a much more "normal" lens. Some were built of covert photography ...
  • I have been there and done that and come part way back. What will suit you depends on your end use for your pictures.  I put some on the net and some into photobooks about places I go.  My wife and ...
  • Another point that may be of interest, it is a medium format film camera taking a 6cm by 6cm negative that is square frames. Usual lens was 75mm making its field a bit wider than than full frame ...
