Here's an old thread I started on this using FoCal:Thanks Mackguyver your post is very informaive
You're right, those 60W are equivalent to incandescent.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.

I have ordered a lot of new stuff from them.Same here. 90% of my gear is from that store. Thanks for your reply
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 ...
16-35/4 L IS
24-70/4 L IS
70-200/4 L IS
300/4 L IS
The 85 f/1.8 is not even close to the 85L
Try these on a 85 f/1.8 :
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!
