I read the 1st gen RoHS was about 2005 or so and was aimed at the electronics industry. So it caught optical glass makers like Zeiss & Schott by surprise a little bit. Didn't RoHS get a re-write a ...

So what is the component that wouldn't be compliant in a mid 80s' lens?

I wonder if the Sigma 500mm f/4.5 is the same formula as the Pentax 500mm f/4.5 in that case.

Ha!  I only listed the highlights.  There were easily 40 more models like the 120mm & 150mm f/3.5 mid-telephoto primes in the brochure.  And there were 6 TCs with a separate set for lenses over 300mm.

If you mean radiation, none of them were after the 70s.  Japan probably didn't need to follow the EU's RoHS in any case.

This will probably make it worse. I'm looking at Asahi's lens brochure printed in 1985.  They had: F AF 35-70mm f/2.8 - (That's correct a fast AF lens in 1985) A 15mm f/3.5 A 28mm f/2 A 50mm f/1.7, ...

Mostly photocopiers, like Canon?  They have two camera brands Ricoh and Pentax. Asahi Optical, do you mean that?  One of the industry leaders in 35mm film days. My opinion is modern cameras are ...

I have Sigma 150-500 APO OS.  I recall it was less than 800$ a few years back when I got it but I don't think Sigma makes this one in K-mount anymore.  Sigma replaced the mount ring for free to ...

I don't recall any assurance such as this being given.  Can you point me to some Ricoh (or Hoya) press release that says this?  I did see they filed a patent for a stronger motor but it might be ...

Yes, they should let us know if they can't.  But maybe they are still working on it.  I've always said the h.264 codec is harder to physically stabilize than the M-JPEG avi one in the K5.  h.264 ...

I didn't switch systems.  I did shoot with a 6D for a couple of years.  I used Canons 17-40 L and 70-200 IS L both f/4.  The AF system on the 6D is very basic compared to a K1 and it is amusing to ...

Here is it from the news article: "This approach means the D850 is not ISO Invariant, but not in a bad way: it's not because the low ISO modes are adding a lot of read noise, but because the higher ...

I should have spotted this because Sony didn't show a FF BSI sensor at that MP count on their sensor road map.  And DPR casually announce it isn't ISO invariant like the big Sony sensors nearly ...

I kept 60-250 for this range.  If I need faster for portrait I use FA 77/1.8 or Rokinon 135/2 with focus trap.  I have thought about DFA* 70-200 but the price and weight keeps me scared off.  When ...

Nope.  I do it to.

I noticed top 9 of 10 active threads last time I logged on were posting photos and talking about photography rather than gear (or lack of).  Great job forum members!

They announced Theta V and Silver K1 already.  It's hard to keep up.  :-)

Yes, I was thinking wildlife in that thread but one has to adjust as best they can for different subjects & conditions.

I found Sony's 24-70 f/4 to be both expensive and poor and did not keep it.  I hope the 2.8 GM is a lot better especially for the price.  The 85 f/1.4 is supposed to be very good but 600$ more ...

Sad to say, but not a laughing matter.
