Change up

Got an opportunity to dump my Sigma 50mm f1.4 on someone who will be using it for video purposes. I did not feel bad selling to them (with full disclosure of course) about my issues with this lens. They were fine with it since it is strictly for video...

As a result I will have some funds with which to do some upgrading. I have really enjoyed the sharpness of the 17-55 and although it is not as near the subject isolation I get with the Sigma, at f2.8, the Canon is wicked sharp and with IS I can hand hold in pretty dim situations. The only issue is that is a a big honkin' lens!

Bottom line is this. With about $980, I was thinking:

70-200f4L IS or 70-200 f2.8 NON-IS (used of course)

#1 - This gives me 17-55 f2.8, 85mm f1.8, 70-200 f4LIS or f2.8

OR

Since the 70-200 is mostly an outdoor lens for me, should I go 70-200f4L and get a Sigma 30mm (thoroughly tested of course!) or Canon 50mm f1.4

Since the 17-55 is so big, sometimes it is nice to take of the grip off the 7D or grab the XSi, and just go with a single prime for a nice lightweight package. That's where the 30 or 50 would come in...

#2 - This would give me 17-55 f2.8, 30/50mm f1.4, 85mm f1.8, 70-200 f4

The latter seems more well rounded, but the IS on a long lens would be nice. A potential 3rd option - Option #1 with a $100 add for a 50mm f1.8 II? This would provide a definite light lens, and with the 7D's high ISO capability, I could stop down for sharpness (I had to on the Sigma anyway!)...

#3 - This gives me 17-55 f2.8, 50mm f1.8, 85mm f1.8, 70-200 f4LIS or f2.8

Thoughts? I shoot mostly family snapshots and vacations. I like car shows, and some urban night shooting as well. Some feeble attempts at fun portraits for neighbor's kids and stuff like that. Not a pro, do not get paid...

Thanks in advance...

I think #1 is probably the best choice if you are concerned about weight for traveling. IS on long lens is definitely needed for all sorts of situation if you hate tripod.

For best quality with prime, #2 is obviously better. I would not give up 50mm so soon because I have often found 85mm far too long for indoor shots on a crop. I can usually live with 50mm on a crop. I think you will not like #3 so much because 50mm 1.8's AF will absolutely kill you after using Sigma 50mm 1.4. You will likely ended up buying it back later. At least that what I did.

I bought a Sigma 50/1.4. Sold it to get a Canon 50mm/1.8. Tried a few MF 50mm 1.4 along the way. Switch to Canon 50mm/1.4. Eventually I switched back to Sigma/1.4.

Option 3 sounds better

But.. Id go with:
17-40L, 35L, 70-200L F4 IS

With all the issues I have had with the Sigma, not sure I would go there again...although the 30 seems less problematic. I would not mind giving the Canon 50mm f1.4a try...
