Works great, IMO.  You need a stable tripod, and give it lots of light, ideally >10 EV (it reports light level) from an incandescent source or direct sun (not fluorescent or LED).
I have question regarding light source. 
Is one halogen lamp 150W is sufficient to properly illuminate  the target? I find it difficult to acquire incandescent lamp ( in my country of residence) with powerful bulb. Mostly LED or Fluorescent with max power 60W and those are not recommended for Test
I hope you don't mind asking me this question in your post gqllc007

In a dark room?  Probably not even close.  You can't do a accurate job when adjusting manually either, in low light, AF systems operate erratically.  FoCal will tell you the light level and warn you if there is not enough.  What happens in low light is that results are not repeatable, so you never are sure that the value you get is the right one.

A 60W Fluorescent or led bulb would be fine, but I doubt if you will find them, the ones you are talking about are likely 7 watts.  I use twelve 32 watt CRI 98 fluorescent tubes, and even then, I'd like more light.  They have reflectors as well.

Go outdoors on in the early morning before the sun hits your target, or on a bright but overcast day, you should have adequate light.
You're right, those 60W are  equivalent to incandescent.
Going outdoors- I'm worried if I will have enough time to do calibration As I live in Middle East and Sunrise and Sunset is much  shorter here than in other part of the world
I saw on DP AFMA tips where Neuroanatomist was using 3 lamps each 150W  for the LensAlign MkII or the DataColor   SpyderLensCal . I cannot find lamps  which are able to accept more powerful bulb.
How about 500W

« on: February 07, 2015, 01:36:21 PM »

I bought a 100-400 and 15-85 from b&h. I bought 9 or 9.5 they were both basically brand new. The 100-400 was 6 months old based on date code.

Thanks
I just saw today that they have 400mm f2.8 IS L for 6K + (9+ condition). Even though this is a monster it is very tempting. GAS damn you

Thank you all for your reply
I have checked Adorama, but they have fewer choice in compare to B&H at least  for supertele.
Regarding KEH I did know this company before but it is worth to check, Thanks
As for B&H, I have gift vouchers for 850$ already so I was thinking that this will be my first to choice to use it/buy it from

Lenses / B&H USED DEPT Supertele
« on: January 27, 2015, 01:21:05 PM »
Dear all
I wish to purchase my first supertele- preferably 300mm 2.8  IS version I for sports and maybe some wildlife with use of Tele 1.4III or (2III after I will purchase this one) in the future.
To cut story short. I wonder if anyone bought used lenses  from B&H store. How their rating system for used lenses look in reality. Your thoughts and experiences
I'm not U.S resident so buying from CPW is not an option  :( If someone ask me to pull trigger for Version 2
Any info appreciated
Regards

Lenses / Re: The f/4 Pentacon
« on: December 31, 2014, 01:46:43 AM »
Leaving for a trip pretty soon, and wanted to assemble the best range, lightest weight, reasonable speed, and affordable outfit I could, and ended up with these five guys I dubbed "The f/4 Pentacon". Did not set out to select all of them with f/4 but it just sort of happened that way. No real questions or issues here, just thought it was interesting to share ...
8-15/4 L
16-35/4 L IS
24-70/4 L IS
70-200/4 L IS
300/4 L IS

If  only 200-400mm F4 Tele would be much lighter and more affordable you would have perfect quintet ;)
By replacing 300mm F4

Lenses / Re: buying advice: canon 85mm f1.2 II or f1.8?
« on: December 18, 2014, 03:37:03 AM »
The 85 f/1.8 is not even close to the 85L

Try these on a 85 f/1.8 :P:









Clartephoto these are really nice
 Unique look and that blur.... Simply amazing
Now I really want one

Hi all, I'm here again with a buy question: lots of online reviews state that the 85mm f1.8 is nearly identical to the f1.2 II in terms of image quality when stopped down to f2. It even focuses faster than the L version. All that the f1.2 version has going for it seems to be that it is very sharp wide open, and has slightly better sharpness and contract than the f1.8 version. Again, money is not an issue here. Is the f1.2 II worth my money with nearly identical visuals and even slower focus, to be offset with f1.2 for low light conditions? Let me know your real-world thoughts! Thanks!

dash2k8 you should get 1.2L version You said money is not an issue.
Don't want to spend money , rent 1.2L before you purchase to make your decision more firm

I just found that B&H Photo no longer keep  expected availability November 2014
Adorama still keeps it expected availability November 2014
Camera Canada shows no expected date of availability
No news emerge in net. No new sample photos
Is this means that release of this item can be next year?
