  • There are some interesting lenses in this thread. The Mamiya 60/2.8 macro was a smoking good deal at $10, and then you posted this one... if you haven't already you may want to look this one up. ...
  • Because of how and where I shop, it'll be a while before I can comment on Zeiss lenses :-) The brand that stands out from the small list above for helicoid issues has definitely been Nikon for me - ...
  • https://jonasraskphotography.com/2017/08/16/minolta-x-fujifilm/
  • I should have worded that a little better - replace 'IBIS on and off' with 'cleaning mode on and camera off'. I put the camera in cleaning mode where it vibrates the sensor and then locks it in ...
  • For the SEL2870 here is a thread where I demonstrated some field tilt and compared it to an adapted Vivitar 28/2 (which is by no means a perfect sample): https://www.dpreview.com/forums/thread/4248438
  • Created discussion thread A7 II Field Tilt
    While the A7II kit is on sale I thought I'd start this thread and ask a few questions. I bought my used A7II kit just under a year ago for what *was* a very good price (still cheaper than the ...
  • With a larger sensor it will quite literally use more of any FF lens' image circle than a FF sensor - so in some ways you'll get more out of any of those lenses than with any other camera: a ...
  • Replied in Schneideritis?
    Edit: looks like two others beat me to it. Do any of the images provided on the eBay listing show the lens at this angle? This looks like something that would have already been there as opposed to ...
  • This may be relevant: https://www.dpreview.com/forums/post/58196368 Ignore my post in that thread though, hehe.
  • I'm now thinking that the rear-most 'element' in the mir.com.my diagrams is a drop-in filter, and that the diagram isn't accurate as to its position, or it's the film plane and they are way ...
  • How about some pics of this rare bird, especially near/inside the mount? They'd be helpful. How wide is the inside of the lens at the mount? How far in could a teleconverter protrusion go? Looking ...
  • I uh, I think frst16 may have been commenting on the OP's exchange with the seller as opposed to your response.
  • If the spots are small it sounds like those would not be the cause. It would have to be pretty significant damage to cause as much SA/haze and/or contrast loss we are seeing with one of your 38/1.8s. ...
  • Replied in Hmm...
    Other thoughts are that it could be a missing lens coating, an unpainted lens edge (someone could have accidentally cleaned it away), missing flocking/baffling, or a missing spacer somewhere. ...
  • Reversed rear element?
  • Replied in Vintage Lens
    It could be either D-mount or C-mount. You could have the seller measure the outer diameter of the threads to narrow it down. D-mount has a thread diameter of 15.88mm (0.625 inch). C-mount has a ...
  • Replied in Yes! Macros
    Ditto, it's of my opinion that macros are always worth trying out. They're always pretty nice and they're versatile. I haven't managed to use the 55/2.8 but I have had a couple slightly different ...
  • Any effects from this tiny chip may be hard to notice. It might be the kind of thing that is measurable but not necessary observable or significant. Try stopping the lens down as far as it will go ...
  • Pricing the results of the study at $20k is such a dilc move.

  • Such a nice looking camera and lens combo...!
