dansclic: One of the recent lenses that makes you decide to invest into mirrorrless .
How can you reasonably invest in a. 900 gram lens that you will handle all day’long ?

Of course mirrorless is an option... Still another option is a mobile phone.

Jacob the Photographer: Seems to me the 'Business Ethics' in Germany are seriously corrupted.
Think of Francke & Heidecke >> Insolvent somewhere in the 90's >> Became DPH >> Rollei trading company branched off >> DPH became insolvent around 2000 >> Resurrected under slightly other name >> insolvent >> resurrected ..... how many guillible investors are sucked of their savings ?
An older Dutch / German story: The once famous Dutch airplane manufacturer 'Fokker' - one of the pioneers in aviation was taken over by a German airplane manufacturer from the Dutch government somewhere in the 1980's if correct. Within about a year the now German owned 'Fokker' factory was shut-down but not after all its patents were siphoned off to the German owners.
So far for business ethics.
The Millions of Euros taken by the owners of Meyer Optic Gorlitz must be hanging around somewhere - in the pockets of broadly smiling ........ ?
'Ethics' - soon a forgotten word ? - lets make sure its not !!

Fokker was notorious for its crashes. Their patents obviously didn't help themselves.

To my knowledge color processing requires temperature control with very tight tolerances. (+/- 0.25C for the developer, if my memory serves me right). I wonder how this simple setup achieves this.

@Zdman: Capacitor problem is not capacitor manufacturer problem if you use 10V capacitors on a 12V line. They should have used capacitors above the working voltage. The correct value should have been 16V.

@jwasturias: Faulty capacitors are not the norm. I have an LG plasma TV that is about 12 years old. It is still functioning well in my summer house. I also use Pioneer HT receivers and I never had any problem with their electrolytic capacitors. I also build DIY projects (class A power amplifiers, phono preamps, etc) as a hobby. I never had any problem with their electrolytic capacitors either. But Samsung... That's something else... Using 10V capacitors instead of 16Vs? That is something criminal!

And the interesting point is that Samsung never produced a service bulletin warning technicians to upgrade those capacitors to 16V (which is the proper rating of a capacitor to be used in these circuits). When TVs came to service centers for repair technicians simply replaced the faulty 10V capacitors with ones with the same rating.

I would never trust Samsung. Ever!

@CarpentersEye
Have you been living on Mars past few decades?
If you don't know the incident that is your loss.

BTW do you think Samyang-Sampo-Samsung brands sound similar? I don't. When I speak or write about something I say things I know!

Do your own research... Google "Samsung TV capacitor failure scandal 10V 12V"

I personally never purchase Samsung products for a different reason... In their TVs they manufactured in early 2000s they had used 10V electrolytic capacitors in circuits with 12V on them. Needless to say they went poof one after another, usually just after the guarantee period was over.

pedroboe100: I'm sure it would look and work well with the smaller limiteds.

I think long/heavy lenses should be handled by the lens, not the camera anyway.

dash2k8: Several ppl saying their Manfrottos fell apart. Sorry to hear that. I've had several Manfrottos of various sizes over the years and they're all still in great condition.

My compact Manfrotto's leg clamps disintegrated in a few years. My much older Slik is still going on well. It (Slik) seems to be built for life.
