Outdoors you'll have plenty of room with the 85 to get full length, but indoors you'll only have enough room for head/shoulders to maybe half length.

Your light measurements are off. Yes, on paper the 1.4 and 1.8 are brighter than the 70-200 f/2.8 but in practice the difference is greater than you think. The primes both give an extra 1/3 stop light transmission because they don't have as many glass elements in them.

Also, the 50 at 1.4 is pretty soft. Not too usable in my book. I consider it to be a good f/2 lens. The 85 is also a bit soft wide open so in my book it is an f/2.2 lens.

Between the two, the 85 is the better for IQ. Both give higher contrast and better images than my 24-70L.

I'm liking primes more and more ...

I've had the 85 1.8 and now have the 100 f2, same lens. Either one are both better than the 50mm 1.4 AF is more accurate, everything is better wide open, the feel is better, they're just better lenses.
Strange thing about my 50 too is that it loves the IR assisted focusing more than sunny day daylight focusing. Pisses me off too. Same distance, comperable contrast, same aperture.
Not saying the 50 is bad at all, it's just not as up to snuff as the others.
Personally, I'd change your order.

Since you've owned both the 85 & 100, which do you think woud be more appropriate for shooting a sport such as hockey where some arenas have poor lighting and fast AF is needed?

My 85mm f/1.8 came in today! A few test shots, but going to put it through the works this weekend. A bit long indoors, but that just means I'll need to be more creative about it!

Having fun with primes!

I love my 50mm f/1.4.

I have taken tons of portraits with it and they have all been great really. I do get some focus hunting in some situations, but mostly good.

But the 85mm f/1.8 is still on my "to buy" list :P

Got it yesterday - did a few test shots (at f/1.8, of course!)

Here's the fifth shot out of the camera!

I'm really looking forward to working with this lens more. It's going to stay on the body for a while......

Here's another one from today. Even though it's not at f/1.8, I am simply amazed at the keep rate of the shots out of this lens - it rivals my 24-105L as far as keepers, and this shot is perfect to me (then again, it's of my daughter!)

I've done a 100% crop on this one as well - it's so sharp I'm considering softening it a bit!

Nice shot Djeuch, my mind keeps telling me I should off the 85L and go for the faster focussing 1.8 and use the rest of the $ for airfare to some beautiful beach in the middle of the pacific....Shots like these don't help:rolleyes:

Djeuch you have a beautiful little girl ~ that second pic is just too cute.

I to am planning to get a 85mm f/1.8 soon - I have a little concern about running out of room inside with my 40D but with the spring and summer months comming upon us I expect to have a great time with this lens out doors.

My 4 yr old son will run and play in our yard untile bedtime and I cant wait to get some of those low light shots of him.

85mm is definitely "too" long indoors, but I've still pulled off a couple. Outside, it's so awesome, and it's incredibly sharp. I see you've got the 17-55mm, so you're actually very wide compared to my option (24-105L) and decent on low-light, and a Sigma 30mm, so I can't see how you can go wrong with the 85/1.8!

Oh man, I just bought the 100mm macro but I really want a 85mm f/1.8 for indoors sports / outside portraits.

I have both. Over all I like the 85 1.8 but use the 50mm 1.4 more due to the fact that I use a crop bodied camera. The 85 1.8 has better IQ but to long in certain situations.

Djeuch, how far away were you standing from your daughter in that shot?
