  • Out here in the desert southwest the parks and open areas are pretty sandy.  So after a few throws a soggy tennis ball will collect a lot of dirt that is abrasive to the teeth when a dog catches ...
  • Your Aussie looks like mine.   Teeth worn down a bit from the dirt collected on the tennis balls.  I got a scolding from the veterinarian.   Hard to say no to ball chasing though when first thing ...
  • "Is "anything" in focus ??? Or does the lens just go "fuzzy" ???" To answer your questions simply about being focused past infinity. Nothing is in focus on the sensor. The image where the sensor is ...
  • The link below may give you some hints about what you might get going AA-less. The Pentax K5II had an AA filter. The slightly higher priced K5IIS did not. https://www.dpreview.com/reviews/pentax-k- ...
  • LifePixel removed the IR filter on my Olympus EPL5.    Whole process went smoothly.  I am likely to be a repeat customer with them. I did not even think about the AA filter though.  I will be ...
  • Lexar ain't what it used to be https://www.dpreview.com/news/5923190395/lexar-acquired-by-chinese-flash-storage-maker-longsys
  • One camera to consider would be an Olympus EPL7 or EPL8.   The screen on my EPL7 flips down so it faces forward.   It is not considered "fully articulated" because that implies even more ...
  • Just to expand on that for the benefit of the OP A K70 is twice as loud in LiveView as in regular mode.  Because there are two actuations, and extra one is needed to use the PDAF module for metering. ...
  • Commented on photo Dog in Yard in OpticsEngineer's photo gallery

    Buster started jogging with me when he was still a growing dog.... about one year old. As he got more used to me and my dogs I saw that he had broken loose from being chained in a yard. A wire...

  • That is my belief as well.   That Pentax has already worked out deals with Sony and we will see Pentax mirrorless come out using Sony sensors that make PDAF modules pointless.  My guess is ...
  • I think this Black Friday deal would work. $449. https://shop.usa.canon.com/shop/en/catalog/eos-rebel-t6i-ef-s-18-55mm-f-35-56-is-stm-kit-refurbished https://www.dpreview.com/reviews/canon-eos-750d ...
  • "But she wants what she wants,.." you are a wise man to rank that highly
  • I have both. I got the D750 because I can borrow lenses from work. But then there was a great 6DII refurbished deal last year. I have kids so LiveView AF is something useful for me getting down at ...
  • I have both. Get the KP. Better autofocus. Much quieter shutter.  The K70 shutter makes a racket something like breaking the bone of a chicken drumstick.
  • nice article.   pretty well reasoned.   thanks for sharing.
  • Commented on photo Diner_white_corrected in OpticsEngineer's photo gallery

    Last spring we had a few German exchange students visiting our school. One stayed with us. We went quite a few places with them, showing off the state as best we could. We were kind of surprised...

  • "But 2019 will be a nice Pentax Ricoh year, that's fact." Thanks for the update. I always appreciate your hints. I don't have any specific wishes.   Just a happy willingness to see what surprise ...
  • Replied in The bible
    Many years ago, my first week on the job straight out of college, my boss handed me the RCA Electro Optics Handbook, called it the bible, pointed me to the section on probability of detection and ...
