Lenses / Re: Street Photography 35mm/50mm + DC?Help
« on: April 18, 2013, 01:15:11 PM »
Voted option #4. Sigma 30 is awesome, and will save you some money over the L. As far as a 50, I think you'll have a hard time using that 1.2 aperture on the L, because street is usually not about absurd bokeh. Since you're likely to want to stop down a bit for more DoF, again, the 50 1.4 will save you a lot of money. Personally, I find 85 a bit long for street photography on crop, but I like the look my 50 gives, which is about equivalent to 85 on FF. Plus, 3 lenses is greater than two! And if you find yourself not using/liking one, you can always sell it.

18mm?  What the heck is it with these idiotic lens makers.  We've got the 17-55, 18-55, 18-135, 18-200, 18-270 and now 18-35.  What do we have that starts at 24mm-equivalent?  The only one I own - the 15-85IS.

f/1.8 sounds interesting, but not if it starts at 18mm!!!


Well clearly they sell plenty of 17- and 18-something zooms, so I don't know if I'd go so far as to call them idiotic... it seems to be working. For most people the extra 3.2 or 4.8 mm don't seem to be make-or-break, and if they're that big a deal, they probably have a 10-something to get even wider...

I for one, am excited to see what this lens can do optically, and what Canon and/or Nikon might do in response. Suddenly a 2.8 zoom isn't as fast as it gets, and if they can do it in an 18-35 (much wider than "normal"), I'd be really curious to see what a 50-100 might look like for indoor sports. (doesn't have to go wide-tele, just normal-tele, still only 2x zoom, but could be very useful). Even if this came in at $1000, with similar optics, I'd consider giving up the extra 20mm of my 17-55 to get the extra stop-and-a-third of light from this lens.

That's what I was looking for. I remember reading that they were going to update the 30mm when they announced the 35mm but I guess I didn't realized it was going to be this quick. Has it been confirmed that they are any different besides the cosmetics and the USB dock?

check out the corner MTFs and the optics diagram:

completely new and different optically.

Edit: OP, just got through watching the video. Thanks for that review- I've heard hit-and-miss things about AF, so I'm glad you found it to your liking, because I'm strongly considering this lens!

also get the sigma 35mm f1.4 its half the price of the 35mm L and its better too ;)

Ignoring the body-choice stuff (I love my 7d, and have been quite happy with the IQ:$$ ratio, but I'm also usually in pretty good light), I would get behind this recommendation of the sigma 35 over the 35L. Sharper, great colors, reviews all say the AF is as good as the 35L (never used the canon, so can't comment personally), etc etc.
It's a shame when so many people that admittedly never have used the 35L is recommending 3rd party alternatives. I've myself never used the Sigma, but the 35L is a top notch lens. Not cheap, but it has a proven performance and quality record over 14 years which the Sigma doesn't.

Never said it wasn't- the point is that sigma has caught up, and the Σ35 is now every bit a top notch lens, for $900 new...

I guess this is a joke - but if serious it makes me wonder, as a Rebel user, if one could damage a pro level EOS by trying to push in an EF-S lens?

Yes, the mirror would collide with the back of the lens.

What FLs do you most often use your 17-40? That's an important starting point. 24L is going to have much better FF corners than 16-35 as well as the obvious aperture/FL differences...

I think it may be a new canon mirrorless announcement :)
and I think it may be a 7d2 that shoots 12fps, has 1dIV level weather sealing, 82pt-AF, APS-H with 5d3-like ISO noise, for $1800.  ::)

I get the sense that you are new to the details of photography, so here are a few basic points.

Your prior camera, the 600D, was a crop-sensor camera using the EF-S mount.  This sensor was smaller than the full-frame sensor in the 5D series cameras (and the 6D and 1D), using the EF mount.  So, the 18mm wide end of your EF-S zoom lens on the 600D is actually equivalent to a 28mm EF lens on a full-frame camera.   

There are a number of EF lenses that cover this range.  For primes, you could look at any of the 28mm lenses.  If you are shooting handheld from a ladder, you might consider the new 28mm f/2.8 IS lens, with image stablization that will help with any blur from handholding.  There is also a 20mm f/2.8 lens with a wider field of view that is inexpensive.  For zooms, there is a 17-40 f/4 and a 16-35 f/2.8 that would probably work as well.  Zooms generally have smaller apertures, so they require more light, but that should not be a problem with a 5d mark 3 or 6D (although the 5d mark 2 it may be).  For wider apertures (1.8, 1.4, 1.2), note that the field of view, or the area in focus, is very narrow.  For more detail, you want smaller apertures (larger numbers, like 5.6, 8, 11, etc). 

The TS-E lenses are manual focus, and would require you use a tripod and spend lots of time with them.  The "stitching" of images is also more time spent on the computer afterwards.  It does not sound like that is what you are looking for. 

However, changing lenses is not hard or time consuming, and you could also get a 100mm f/2.8 macro lens (the version with the IS if you are shooting handheld) to take your detail shots right after you take your wide shots.  Or you could get the EF-S 60mm macro lens and put it on your old 600D for your macro shots, but note that this lens will not work on your new full frame 5D.

Also, you should look into the 6D camera.  Its built-in wifi might be useful in your working environment, and the autofocus will be plenty for photographing stationary carpets.  The images should look just about as good as the 5d Mark 3, and maybe even better than the 5d mark 2.  (This is the kind of thing that people on the internet argue about a lot, though).

I hope this helps.

Pulling two little details out of this for emphasis: 17-40 would be significantly wider on FF than 18mm was on the 600d. So it might be wider than you need, but might also mean not having to go as high up the ladder, which I'd think would be nice. Plus, it's got great optics, is very reasonably priced (available as a refurb from canon for $571 right now), etc etc. I'd say that would be a great lens choice... Second, the 6d is also available pretty inexpensively right now, and has very good IQ, and is definitely worth considering. You'll notice a huge increase in image quality with that combo over what you were using previously.

I wanted to get the IS II but it looks like budget will be an issue.   :'(  If I get this lens, this is the only lens I would be able to get and I wont be able to afford a wide lens before the season starts.  I'll go ahead and get the f/2.8 non IS version and get it before the end of May.  I can shoot video with the wide lens or use a monopod or tripod, if I have the 70-200mm attached.  Then I try to get a wide lens by August.  I could really use the $900-$1000 extra dollars towards another lens.

Maybe next year, I can get the IS II.

keep an eye on the refurbs- the 70-200 2.8 non-IS had been in stock for a while, apparently now is sold out, but it may come back before May. Great way to stretch your budget a little further. 10-22 and 17-55 IS are both in stock if you want to get a wide lens now...

Just like WiFi was first on the 1DX :)

Just to nitpick for the sake of nitpicking (I agree with what you are saying in general): Wifi is hardly new technology anymore... ::)

Also, since this thread has already deteriorated like dozens before it, I guess I'll share this observation here. Canon may be a market leader in terms of sales, profit, whatever, but in at least one market, they're WAY behind. I was in Washington, DC this week for a conference at a hotel right across from the national zoo. I would go for a walk in the zoo on lunch break, because the weather was nice and it was outdoors. I saw dozens of small Nikon SLRs, and in 3 days of walking around, only two other Canon SLRs: one CPS member with a 1Dx+300 2.8 II, and a 7D+70-200 IS II. Not that this was conclusive in any way, it was just an unexpected observation I made...

Oh well basically the same sensor again.
Yeah but we knew that... They don't want to undermine the 7d2.

I fully expect the 70D will be a refreshed 7D: "new" sensor with on-chip AF, built on the same process. Better sealing than 60D, somewhere in the 6-8fps range, and decent (maybe 7D) AF. Given that 7Ds now go for 1300ish new, I'd think that 7d specs would put the 70d right where they want it in the lineup. That sets them up well for a 7d2 to be a better camera, that they can charge accordingly for.

EOS Bodies - For Stills / Re: Batteries and AF

Thanks all for the replies!

Lets see if I can answer all these questions:
-I do not use ML; not that crazy a question, I've considered it, but no, I'm using factory firmware.
-Longer version of the anecdote: she said she was manual focusing because the camera wasn't focusing, but she thought it was fine at the beginning. Looking at her shots, she nailed some running dogs, so I'm pretty sure it was fine when she got it, and died during that day.
-I have not really tested any of the batteries, since I usually recharge at the end of a day of shooting. But I have fired off 2k frames in one day of ski racing, and not had to change battery. Unfortunately don't remember which battery that was... Statistically speaking, twice as likely to be a third-party one, right? ;)
-battery terminals look clean to me
-both third party batteries AF right down to one bar.
-this OEM battery is ~5months old, can't have more than half a dozen load-cycles. Came with my 7d when I got it, refurb. Makes me less likely to bother returning it... If it is a faulty battery it seems more worth my time to recycle it and get another $15 wasabi power one... They've been great in my gopro for 2 years, and so far so good in this context as well.

Edit: because I got it from canon direct, I'm inclined to think its genuine. Now, it may be refurbed and already have a ton of load cycles, but I think it was in retail packaging...

Question for all of the collective wisdom here:

The other day, I let my sister borrow my 7d. She's used to my dad's 60D, and probably getting a rebel of her own, so I wasn't too concerned about her messing anything up. When she gave it back to me, it wasn't AFing- with any lens, regular or live view, nothing. When I MFd in one-shot mode, I got a focus recognition beep. Checked all the connectors, they were all clean. Finally, I looked at a pin diagram, and seeing that a pin provides 6v for the lens AF motor (something I logically knew, that was just the inspiration) I popped in a fresh battery. Suddenly, AF worked again!

My questions:
Has anyone ever observed behavior, where a battery shows 2 bars of remaining charge on the top LCD, and the camera takes shots, but doesn't have power to AF?
The battery I had in was OEM. I swapped in a Wasabi power LP-E6 clone- any OEM/3rd party compatibility issues? I'm inclined to think no, since the OEM was the one that caused the problem.
Should I do anything? At this point, this is purely an exercise in intellectual curiosity- that wasabi power LP-E6 has now taken 1,000 shots without issue, so I'm curious more than concerned.
