Lenses / Re: Canon 100mm macro IS vs non-IS - any further input?
« on: January 06, 2013, 04:29:41 AM »
Thanks Marsu, I'm concerned about the weight of the 70-200/2.8L2.

Me too, and I'm a large male :-> but when I tried the 70-200/2.8is2 I immediately knew that that's a decisive difference to the also not lightweight 70-300L - the 70-200/2.8is2 creates much more torque on the wrist because the lens is longer (and next to that is not balanced on my lighter 60d body or the 6d I plan to buy).

I keep being told a strap system does some magic, though I haven't tried it - but the 70-200is2+flash-bracket+5d3-type body is way out of the "fun" league, however as a pro shooter only you can decide if the better af capability (larger aperture) and f2.8 @200mm makes it worth it to you anyway - renting it might be a good idea in this case.

Any input regarding the other 2 lens choices I mentioned? Thanks, Debbie

There are a lot of threads on this, I got the slightly more expensive "outdoor" 70-300L because I don't mind the extending zoom design and non-constant aperture but want the larger zoom range and smaller pack size. Btw: The newer 70-300L is better on a 5d3/1dx since it's got more current af system, doesn't matter for all other camera bodies. Concerning iq, the 70-200/4 might be slightly sharper (see iso crops @ the digital picture), but nothing that would make a real difference - if you want "THE" indoor zoom lens the 70-200/2.8is2 is the one to get anyway. My only issue with the 70-300L is the missing af range limiter (thanks, Canon).

I don't think 10€ more will break the bank.

Yup, just ordered it directly from China (to save 5€ in comparison to a German delivery) - now I just have to wait a month :-> ... and I think the Canon flash system is currently overpriced since only the 600rt is available and I certainly cannot afford more of these, but I thought one would be a future-proof bet and it has the nice 200mm reflector.

My usage would be weddings plus typical insect and floral macro shots.

Of course get the L version if you've got the money the better bokeh & sharpness wide open plus IS for dual-use is a no-brainer, even w/o considering the 5d3/1dx lens groups. The non-L is a good budget macro-only solution esp. when the lens is bought used since it's around for some time, the IS doesn't help much @1:1.

Btw the decisive improvements on the L for me are seldom mentioned - sealing (for outdoor macro against dust) and an extended range limiter over the non-L for *non-macro* range that prevents hunting when shooting portraits, the af speed is mediocre at best (it is a macro lens after all).

Forgive my ignorance, I am quite new to photography.  I would like to understand how the 5D3/1DX are not tuned for those L lenses?  And can the camera's settings tune the camera to those lenses?

This is rather ot, but fyi: Download the manual, look under "lens groups" - the full potential of the 1dx/5d3 af is with few lenses (like the 70-200/2.8is2, 24-70ii) and the af spread and precision (double cross, cross, ...) degrades in lower lens groups. This is constantly missed by many 5d3 reviews, it's a shame that reviewers don't deem it necessary to flip through the manual. The lens groups are fixed and not settable in firmware, and it'll stay that way because of the lens' hardware - i.e. that's why the 24-70mk1 is in a lower group than the mk2.

Of course the 5d3 has a much more stellar af even with my lenses than the disappointing 6d af system, and the newer lenses like the 70-300L are much more precise in contrast to the 6d (see the lensrentals review on the 6d af) - but with f4 it's not the full potential, and precision matters most with large apertures (or macro, which is a problem for me on the 60d).

Imho the 5d1/1dx is meant for the current f2.8 zooms and expensive primes, while the 6d is "anti-tuned" for it because all outer points have no f2.8-precision and the center point has non-cross precision for f2.8 (it's a horizontal overlay over the f4 cross) - thanks, Canon... see also a neighbor thread mentioned above about 100L vs 200L on 5d3 in lower light.

Sorry for the length.  Feel free to share your thoughts and experience and contact me if you like.  Good Luck!

Many thanks for summing it up from a user's perspective, that rather concludes it for me - the 5d3 is very expensive for me anyway, I'd rather get another lens (like 17-40L + filter) and some accessories for the price difference to the 6d, and apart from the 5d3 af assist problem the 5d3/1dx isn't tuned for the most of the lenses I use (100L, 17-40L, 70-300L).  Still a pity the 6d is so underspeced and I don't need the gimmicks, but then again no one prevents me from buying the 5d4 in 2015 if I ever go pro...

This happens with the 24-70 F/2.8 II and the 70-200 F/2.8 II.

... imho in this case it's a rather severe difference, because a) given the short zoom range a few mm more or less do make a difference, esp. a difference on the wide end matters and b) the sharpness is always compared the "wide end", but in reality it should be like 24mm mk2 vs 26mm mk1 which might make some sharpness difference.

Simply put, the 6D outperforms the 5D3 for low light focusing.

Having neither access to a 5d3 or 6d, but wanting to decide for one sooner or later it's rather difficult because it's very fuzzy what "low light" is (few people posting state their lens, object distance + shutter&aperture) - and how fast either camera focuses with af assist disabled in lower light.

On the one hand, I am amazed how many people have this problem w/o an official Canon confirmation, on the other hand if the issue is really as severe as it appears to be for "5d3-like" situations there should be an even larger outcry - or Canon really changed something on the latest hardware?

Summing it up, I understand this is an important issue for lower-light shooting like events and receptions where even the up to -2lv 5d3 needs the af beam, and there is no solution in sight except probably using non-Canon flashes, correct?

but for as little as 11x the price you can find it out  :o

I (again) didn't realize Canon does produce the same thing - and given Canon's current pricing policy, I think they should lower the prices so that they're only *10* times more expensive than the same thing from a third party, often they're even content with only 5 times like the ttl-cord or lens hoods :-p

Maybe you're better off with used pocket wizards or some cheaper version of them.

If I should get this than only to attach 1 or max two cheap flashes (like the ring flash advice above) near the camera, otherwise I'd invest in the current Canon wireless system (that's why I got the 600rt) though that isn't compatible with studio flashes atm.

My 60d hasn't got a socket

There are a lot of cheap adapters on ebay.

Thanks, I didn't realize that - though the one I found looks somewhat wobbly when I imagine a speedlite mounted on it next to a manual flash via pc sync: http://www.ebay.de/itm/Neu-TF-321-Canon-E-TTL-Flash-Hot-Shoe-Blitzschuh-zu-PC-Sync-Adapter-/221085648301?pt=LH_DefaultDomain_77&hash=item3379bb45ad

Lighting / When (and if) does a "gold" colored flash diffuser make sense?
« on: January 05, 2013, 07:40:59 AM »
I've seen there are "gold" flash diffusers like the ones from sto-fen that are supposed to give, surprise, warmer "sunset-like" light. Since I couldn't find any decent reviews...

... does anyone use this kind of diffuser, when does it make sense (broad range of situations or only as a very special effect)? Any sense buying this over flash gels except that gels are a hassle to mount to the flash in addition to a diffuser?

Lighting / Re: Flash head size 600rt vs 580ex(2) ?
« on: January 05, 2013, 07:31:38 AM »
I've read that custom-fit products for the older 550EX can apparently be used on the 600EX, although the fit is snug.


I have searched for the same and found low profiles ones

I admit I've bought a non-low-profile original sto-fen for a ridiculously high price because the low-profile versions looked as if they'd fall off in the lightest wind breeze or camera shake - and I didn't find any comparisons "large" sto-fen vs. the smaller rip-offs.

only issue issue is that they do not stack when not in use as the ones for my 580 EX do. Unfortunately, I have not found a perfect solution for 600EX gel filters and have now resorted to having to make my own ordering large sheets from B&H an velcro off ebay.

That's my problem, too - can you describe (or take a pic of) your home-brew gel holder version?

You're not referring to the effect of using a ring flash are you ?

Nope, but sure looks catchy, but very special and might divert attraction from the overall motive. I do a lot of macro with multiple flashes, and the direct fill flash rectangle is always too much visible in the eyes of animals.

Try joghurt becher with different colors

Thx, that's worth a try, I didn't get the idea myself because I'd suspected the plastic takes too much light away. A plastic bag sounds a bit too much unreliable because it's prone to change form or flatten(?).

Maybe you can add some black tape to a rectangular softbox to fake the look of a window cross.

Oh, well, that's also a good idea - seems I need to bump up my creativity with flash accessories a bit :-)

If your camera has a pc socket you can pick up a cheapo msnual ringflash on ebay.

My 60d hasn't got a socket, and neither has the 6d (thanks, Canon!) that I'll probably buy because it keeps being €1000 cheaper than the 5d3 and hasn't got the af assist bug ... and the pc terminal on the speedlite is incoming only (thanks again, Canon).

Lighting / How to produce circular flash reflection in eyes?
« on: January 05, 2013, 04:43:10 AM »
I've got some flashes and conventional diffusers, i.e. the sto-fen type. But I'm annoyed by the ugly flash reflection in the eyes, so currently I'm looking for a softbox (larger square "studio-like" reflection) and/or some means to produce a circular reflection.

The best I could come up with is this type, does anyone else the conventional rectangle reflection is ugly and has another solution (or something home-made)? http://www.amazon.de/D%C3%B6rr-PRO-4-Diffusor-Canon-580EX/dp/B001BN4T9S/ref=sr_1_2?ie=UTF8&qid=1357378741&sr=8-2

Lighting / Flash head size 600rt vs 580ex(2) ?
« on: January 05, 2013, 04:37:29 AM »
I'm looking for some flash diffuser equipment, but many shops haven't updated their descriptions since the release of the 600rt ...

... and I'm wondering if something that is made to be stuck to the head of the 580ex(2) automatically also fits the 600rt, or do they have different sizes? Thx for the information if someone happens to have both flashes!
