Lenses / Re: 50mm Primes that don't suck wide open?

The Sigma 50 1.4 is very good on the Canon 5D3 body. Something about the 5D3 focus system that just makes the Sigma work perfectly. I say this because the same Sigma lens on my old 7D had the usual focus shift inconsistency.

Naaa, you are just lucky...  ;D
Same luck here, it focuses perfectly on my 5D2, even with the MkII's lame AF system ;)

Ditto, mine works perfectly. Had to send it to Sigma, but it came back spot-on at any distance.

For the price it's very good. I do like the asthetic of the Canon 1.2 better, but then that difference is +$1100...

What are this lens owners' opinions concerning it's AF and build quality? I'm considering one of these.

Soooo....this may be a dumb question....but is the new 70D mirrorless? It has phase detection imbedded in the image sensor and has EVF....so it kinda sounds like there may not be any point in it having a mirror?

My understanding is the entire purpose of the mirror in DSLR is to get a light path to the phase detection sensors which are mounted in a different location than the image sensor (in addition to VF).

Any word on AFMA? It's a non-starter for me without it.

I thought the last was rather noisy. But, at iso 12800 it's remarkably good!

LOL, I knew that would come with the territory when I cranked it up, especially shooting in the shade, but no chance at all to stop the wings otherwise.

Here's a couple of hummingbird shots with this lens and 5D3:

What iso did you use? Speed, aperture?

The first is ISO 3200, f/5.6, 400mm, 1/250th, handheld.

The second is ISO 12800, f/5.6, 400mm, 1/1600th, handheld.

Both are cropped around 50% or so.

It was late in the day and in the shade, except there is some backlighting of the bird on the first shot. It would be nice to have been able to shoot them in full sun so as to get the shutter towards 1/8000th and hopefully get "stopped" wings that are clear.

I borrowed the lens and didn't AFMA it. It's a very nice lens at that price point, I'm sure the new one will be even better, but probably only 20% better for 150% more cash.

This lens isn't what you want to shoot the Milky Way with, but if it's all you have with you, at least you can come home with something. I have to say, I'll never "love" this lens, but I sure do end up using it a lot. "Going on a trip, taking the 5D3 and...the 24-105...". (but I was really wishing I had my Rokinon 35 with me for this shot, wasn't expecting the opportunity to shoot stars so didn't pack it)

Lenses / Re: Can the 70-200 2.8L II IS replace my 100L and 135L?
« on: May 17, 2013, 06:15:57 PM »
I have the 100L and 70-200 IS2. The 70-200 would be wonderful if it weren't such a boat anchor...I hate lugging that thing around. The 70-200 is noticably faster focusing and also focuses in lower light better. They give a bit of a different look but it's not huge imo. There's times for me when the 100L is nice without much in the way of limits on how close I can get.

I agree with others that if you can, buy it and keep the others, then sell something later when you have more first hand experience with the 70-200. It would be interesting to see you shoot the same model with all three in a single session to compare them! Would be fun letting people guess which lens goes with which shots.

theres lots of space because its a desert! thats what i was trying to get across.

A bit off topic I suppose, but depending on what you plan to do with the output, another thing you might play with is cropping at different aspect ratios to emphasize the horizontal vastness. I kinda like 2.66:1 (cinema) to 3:1 aspect ratios for shots like you posted. Might make for an interesting framed/matted print - or might not be your cup of tea - just tossing out an idea. Below is a cinema (2.66:1) crop.

Very pleased to report 100L + Yongnuo 568 w/assist is very snappy in low light with this firmware. I was worried Canon might sabotage the third party lens focus, but Sigma 50 works fantastic with this firmware update.

So are all of the third party lenses still focusing correctly with this firmware version? I'd hate to think Canon would sabotage them with a firmware update but can't put it past them if they sabotaged third party batteries.

sanj...you inspired me to take my 1dx - 85 1.8 combo out on a walk this morning to see if I might come upon something of interest.   

usually I slap my trusty 24-105 on for "walk about" photography, or sometimes the shorty 40, but this was a first for the 85 1.8. 

not a "street shot", but I like this image.  cloudy and gray here today, and considering the setting, i went b/w using nik silver efx.

iso 100

thanks for your post....in the future I'll be using this combo again for "walkabout" photography.

That is a brilliant composition IMO. Very well done.

If/when Sigma updates their 50 1.4 into the Art line, they should make it a f/1.2 just to annoy Canon. Would be awesome!

Well, maybe not to annoy them, but do the new one as f/1.2 and then keep the current 50 to fill the current price point.

LOL, they just need to make sure they do to the current ones whatever they they did to mine when I sent it to them *before* they all hit the store shelves instead of *after*.  Mine was a problem child as delivered, but very well behaved after a trip in for service.

LOL, so when can I pre-order???

As for the 50, I've been pleased with the existing one after I sent it in to service the "front focus up close, back focus at distance" syndrome. They totally fixed it with a firmware update. That said, I'd definitely want to see if the ART version 50 is better than the current version 50 after being dialed in.
