Lenses / Re: TS-E 90mm f/2.8 Tilt-Shift for product photography?

The TS-E 90mm is the lens for small product photography.

See the coin examples here: http://www.northlight-images.co.uk/article_pages/ts-e90_tilt-shift.html which align with what you're trying to do.

So Canon did all of this yet there are stories already about a quick replacement of the 5D3? Well, that tells you how important that list of "improvements" that you listed is, doesn't it?

It tells me nothing. There have been 'stories' of a new 100-400L for what...7-8 years?  There have even been at least two patents. Where's the lens? Stories.

As for a 5DIII 'replacement', I'd say BS and wishful thinking.  Many of the people clamoring for a high MP camera from Canon don't want to pay the price for a 1-series body, and from such dreams, rumors are born.

Let me put this another way. If I pick up and use a 5D Mark III, what am I going to notice as being significantly better aside from the AF? Nothing. What do I see as being better when I look at the images on my computer? Nothing.

So $800 or $900 more for improved AF.

Sorry, I completely disagree with that conclusion.  With a few notable (and *cough* vociferous) minority exceptions, the consensus was that the sensor-based IQ of the 5DII was excellent - it wasn't broke, and Canon didn't fix it.  Because of that excellent IQ, many people used the 5DII for tasks for which it's not ideal.  There's a reason I and a whole bunch of other people had both a 5DII and a 7D.  What Canon did with the 5DIII was, IMO, huge.  They took a camera with already excellent IQ, and improved substantially on the overall performance. 

For 5DII tripod-only, ISO 100 shooters, I can see the incremental nature of the upgrade. But if that's you, the answer is simple - keep your 5DII.

You state, "If I pick up and use a 5D Mark III...," which I take to mean you haven't.

After a couple years shooting a 7D and a 5DII, when I tried out a 5DIII what I immediately noticed was that it felt 'fast'. For example, the difference between the ~200 ms shutter lag of the 5DII and the ~100 ms lag of the 5DIII is very apparent.  My overall impression of the 5DIII is that using it feels like using a 7D from a performance standpoint, and it delivers the IQ of the 5DII - that's a powerful combination, and whereas the 5DII was liked (almost exclusively) for its IQ, the 5DIII is, IMO, the best all-around dSLR on the market.

Yes, the contacts that deliver power for AF also deliver power for IS.

7654
Yes.

In short, the only thing that Canon really got right with the 5D Mark III was autofocus (probably because that was the leading criticism from the 5D Mark II) but in fixing that, it is almost like they ignored the rest of the camera (sensor included.) Oops!

Yep.  The 50% faster frame rate, better sealing, better viewfinder, dual card slots, shutter lag reduced by half, better metering, better ergonomics including a multicontroller on the grip, etc., it does seem like Canon ignored everything but the AF.  Right.

Lighting / Re: How to use flash with av,tv
« on: February 10, 2013, 07:04:07 AM »
You also asked about ISO 400 - the camera selects that in Auto ISO with a flash as a compromise.  Higher ISO means your flash power goes further, lower ISO means less noise.  If you manually set an ISO, you can set whatever you want.

Can't we all just agree to agree?  ;)

Well, received my new tripod a short while ago. It is a thing of beauty, I'll definitely offer that. I think I may have...miscalculated...the height though.  This thing is WAAAY TALL.

Don't say you weren't warned...   :P

For that reason, I'd consider the 3542XLS instead of the 3452LS (although that's really a tall set of legs!).  XLS too tall, LS too short, TVC-34L would be just right.    ;)

Third Party Manufacturers / Re: Best Cap for 82mm Slim Filter

The XS-Pro mount is 3.4mm thick, whichever glass is in it.

I have UV filters because those were cheaper when I bought them.  If I was buying an 82mm filter from B&H today, I'd get Clear because it's $12 cheaper, and more importantly, it's in stock.

For a dSLR, there's no difference between UV and Clear. I'd get whichever is cheaper.

I'd recommend exchanging the slim filters for XS-Pro filters - only slightly thicker (3.4mm vs. 3mm) and has front threads so the Canon caps work.  I use an XS-Pro MRC UV on my 16-35L II, there's no additional vignetting.

Another??

L versions of the TS-E 45mm and 90mm.

70D /7D mark II wishlist
  • A new sensor
  • 20+ megapixel
  • Reduced read Noise
  • 1-2 stops improvement in ISO noise
  • Better dynamic range.
  • Same great canon ergonomics and sensible button layout (hopefully closer to 60D size than 7D size)

Interestingly, your 'wishlist' is a good description of the 6D, compared to your 60D...

Lenses / Re: I want to replace my 18-135 IS STM
« on: February 09, 2013, 09:45:00 AM »
How about the other end - is 40mm wide enough?  If not, you may need two lenses...  If you want something longer, you might consider the 70-200mm f/4L.  True replacements for the 18-135, meaning general purpose zooms for APS-C, are the 17-55/2.8 IS and the 15-85/3.5-5.6 IS.  Both offer better IQ than the 18-135.

If you're ok buying used, you could likely get the 70-200/4 and the 10-22mm for around $1K.  If you really want to shoot birds, get a 100-400 (I see them for $1K used).

Bottom line - decide first what you most want to shoot, then pick the lens that's best for that.

How difficult is it to adjust the partially extended legs to make it level. Is it easy or does it involve a lot of fidling to get all 3 legs evenly extended?

Not too difficult to get close (I usually only partly extend the last leg sections on my TVC-33).  But unless you're shooting on flat ground (and sometimes even then), getting the platform perfectly level does mean fiddling. But with a ballhead, there's no need to level the platform.  With a gimbal head, there is - that's why I recommend the leveling base - you don't need to worry about the legs to get the platform level.
