Re: Why and how are insects attracted to night lights

That sounds magical Robert! The fishing bats were something I would never have even dreamed of seeing. They were taking turns coming in and feasting on fish. It was a little scary and uncomfortable when the larger pelagic fish came in though so I got out. Even on deck wasn't safe. Something big was...

Re: Mitutoyo 10x 0.42 M Plan APO HR lens adventure

no matter how well packed, there is no way of knowing handling care of salvage parts previous to shipping That's the question! Did it happen in shipping or maybe my theory, these could be from a batch that did not make it past someones QC testing. That would explain the low prices and the poor IQ. ...

Re: Mitutoyo 10x 0.42 M Plan APO HR lens adventure

I'm curious about that ultra-wide-spectrum 50x. Is that the actual UV Mitu as opposed to the near-UV Mitu? The objective was not labeled Mitutoyo but had a PN, 378-880, that matched other high-end Mitutoyos in the catalog but nothing matched perfectly. So after pushing Mitutoyo for a couple of week...

Re: Mitutoyo 10x 0.42 M Plan APO HR lens adventure

So both HR mitutoyos were potatoes? I'm curious to see some photos (of the actual objectives) and photos taken using them. Yes, both had bad astigmatism/spherical aberrations. I'll post some sample images later today (they are on another computer). At first I thought it was a smeared fingerprint on...

Re: ultra macro suggestions beyond 10x -- cheaper but ok objectives to play with? Sony aps-c

Huh. Did the body survive intact? I would think the objectives would be the main risk there. Nice piece of kit if it's working. _FS-60.jpg Found it. Image is dated 07-16-2018. FS-60, no FS-100. I still have and use the stand and focus rack unit. I paid $650 with shipping. Thankfully the seller had ...

Re: ultra macro suggestions beyond 10x -- cheaper but ok objectives to play with? Sony aps-c

Huh. Did the body survive intact? I would think the objectives would be the main risk there. Nice piece of kit if it's working. The stand was okay, just a couple of nicks. They are really solidly made and it survived. The XY stage fell to the bottom, well, used to be top, of the box, and didn't mak...

Re: Mitutoyo 10x 0.42 M Plan APO HR lens adventure

I'm literally getting a headache right now just thinking about it, really, I don't normally get them either!

Can I claim pain and suffering damages somehow? #-o

Re: Mitutoyo 10x 0.42 M Plan APO HR lens adventure

Did the other two end up poorly packed as well? It was so odd since what I got from him was packed fine, though they were much smaller lenses. Yes. Second shipment, two more zip-locks, one more sheet of bubble wrap. The weight of the 10x HR made the problem a lot worse I think, 460 grams each, a 1 ...

Re: Why and how are insects attracted to night lights

The interesting part is its not just insects.... One of the most amazing things I've ever seen was on a live aboard dive boat in Raja Ampat, West Paupa, Indonesia. A 10,000 watt light at night brought in clouds of insects, rhinocerous beetles, moths, flies, then clouds of plankton under the light an...

Mitutoyo 10x 0.42 M Plan APO HR lens adventure

Hopefully this information about my experience will help other Mitutoyo buyers out there. A few weeks ago I found a very clean 10x HR 0.42 lens from a seller in Korea supposedly pulled from a Samsung LCD fab late last year. Normally I would not buy a used Mitutoyo but in this case the seller has a 3...

Re: ultra macro suggestions beyond 10x -- cheaper but ok objectives to play with? Sony aps-c

These words are absolutely wild to me, they used to be really affordable or almost free?! Wow! I had guessed they were always somewhat pricey (even though not extremely so), given that I think I keep seeing them for 250+ $usd or so used We should start an "affordable and free" thread for stories.

Re: AstrHori 25mm f/2.8 2x-5x full-frame macro lens

lothman thanks for sharing this, well all appreciate the work and the results! =D> I had totally forgoteen the results from my Laowa test so I checked my test page ( https://www.closeuphotography.com/laowa-25mm-macro-lens-test ).

Re: AstrHori 25mm f/2.8 2x-5x full-frame macro lens

Forgot to mention one thing. Nothing is wrong with a income or profit driven review websites, Ken Rockwell, the most successful online reviewer of all time, his reviews placed above Nikon and Canon, and even BH photo in google results. His website traffic is/was the hundreds of millions a year and m...

Re: AstrHori 25mm f/2.8 2x-5x full-frame macro lens

Eeek, ummm, yeah, that's disgusting. I had seen rumblings online of skepticism around sponsored/corrupt reviews in the photo world (I'm new to having a real camera again as of August), but that's pretty brazen. Rumblings of skepticism? That's an overly kind view of the current situation. In 2021 wh...
