Anyone have any thoughts about this lens? It has the very same, very-nice, appearance as the 600mm & 800mm f8.0 Super Yashinon-R lenses.
It is somewhat similar to a Sun 80-240mm f4.0 that recently ended up on my doorstep. The Sun had too much fungus for me -- but it has a new home. Both the Sun and the Yashinon are two-touch, large, heavy, and have tripod sockets.
I thought I might give it a try, but what are your thoughts?
Incidentally, there is a Yashinon 70-230mm f4.5 on EBAY right now -- with the case -- starting at $0.99. It's not for me, but I'm just passing this along.

I just noticed that the Yashinon-R 75-230 f4.5 is a 13 elements in nine groups design, while the Auto Yashinon 75-230 f4.5 is a 13 elements in eight groups design. Who knows why this change was made, but I'm curious if this change made an improvement?  The results from the Yashinon-R 75-230 f4.5 -- that I have seen -- look GREAT! |

I just received an Auto Yashinon 75-230 f4.5 that I got on EBAY for $15.
It's in mint condition with the case and the super-short, but very well made lens shade. Nice and clean. Looks and works like new. I can't want to try it out -- and I will -- after recovering from nabbing such a GREAT DEAL!!!

Just for kicks, here's the Yashinon 75-230mm f4.5 next to a Sigma 500mm f7.2. They are almost exactly the same size and weight. I hope I don't get them confused!

And here's a look (perhaps I'll have better luck with this image) of the 75-230mm on my Sony. I decided to use a more appropriate Mamiya RB76 long rubber lens shade. The whole thing weighs in at 7.5 pounds -- and took me so long to get it on the tripod that I didn't have time to actually take any pictures before it started to rain -- but that's OK, we are in a severe drought out here! Anyway, the viewfinder at f4.5 is very bright at 230mm. I also like the rotating tripod socket!!! I'm very optimistic.
(FYI, sometimes my images show up and sometimes they don't)

I'm at a loss on why they go missing. I can use the same site address you entered and open the image in a new browser window, so there's no doubt that it exists and it's publicly available. I'm unable to insert your image using your working site link. I'll try just putting in a link to it instead, and see what happens subclub.org/yashinon75-230.jpg |

Well... at least that gets it to open in a new window. Not ideal, but at least it works until I can figure out why they aren't showing. EDIT: I think the reason they aren't showing is that all the web browsers are finally treating them as insecure content and it's being blocked from display by default. This has been on the horizon for quite some time, and it looks like everyone has switched this 'on', so that anything showing as a 3rd party site image through a ProBoard thread post that doesn't use an SSL certificate of some kind is penalized, and their embedded content is now blocked. Here's what I see inside Chrome's site-specific settings page...  |

I'm sure you are correct. I have just signed up for SSL certification for the website. It's basically a good security addition to the WWW, so that nefarious activity can be prevented -- and in the worst case TRACKED DOWN. The only unfortunate side is that it adds to the complexity of the WEB structure & administration, and is an added expense for websites -- sort of like adding a burglar alarm to your domicile.
The installation process is not immediate, but I'll set it up ASAP.
Once again, thanks for your time & help! |

New SSL certs for sites are ridiculously cheap these days (some, less than $4 a year) if you're forced to go the paid route by your provider. Sometimes tricky to install, but once set up, it should be seamless and transparent - even in maintaining the site itself. If you need help, please don't hesitate to ask. |

The results from the Yashinon-R 75-230 f4.5 -- that I have seen -- look GREAT!
