EOS Bodies - For Stills / Re: Help me upgrade my 550d
« on: November 11, 2012, 12:34:04 PM »
You mention being dissatisfied with the ISO performance of your 550D. The 7D uses the same sensor.

I think you'd be very happy with the 5DIII.
I'd also vote for the 5D MK III,  I preferred my 5D MK II over my 7D, but did not do much in the way of challanging sports photography.  The 7D does not have good high ISO performance, but its usable to 1600 if you use RAW.
5D MK II with truck goinng away from me, center point. It was at 5/5.6 which gives enough depth of field at that distance to make fast AF less important.

if it worked or was any good it would be talked about all over the forums etc... if they need to come to you then i suspect it isn't.....
Since the question was asked, it seemed appropriate for them to post a helpful note.  Its not like they were spamming the forum.
I think I had tried it a few years ago.  For a P&S user, or a first cut at processing 1000 images, it might save some time, but, I'd still spend about the same amount of time fixing images in any event.

Probably the most useful things are the more consistent autofocus and the reduced noise in the shadows.  It is just a tool, and since my 5D MK II was getting up there in age, I decided that $2750 was ok, particularly since I got a free 2nd battery out of the deal.  That made it the same price as my 5D MK II in 2009.

Just to see what would happen, I downloaded the Lightroom version.  Since I already had a different external editor, I had to point to Perfectly Clear.\
I then tried it on a D800 image that I had previously edited in lightroom.  The main subject was clear, but it did brighten up a purple object.  Unfortunately, the shadow became purple too.  Then, I tried saving it and got a out of memory message.  OK, I only have 8GB, but it must use a lot of memory.
I tried a image next from my New G1X that had been edited.  I did not like the result, the background was too dark.  The lightroom one button auto exposure looked better.  So, I tried to improve on that, and it did produce a improvement in highlights of a snow scene when based on the LR adjust as a starting point.
Finally, I tried a extreme low light image taken with my 5D MK III at ISO 56200.  It was lit by incandesent light and whites were a golden beige color.  The whites turned to blue green which was ugly.  I could adjust the slider, of course, but it did not correct the tint nearly as well as I could in Lightroom.  The NR was extremely heavy, and much of the fine detail was lost.  Even pullinng the sliders all the way down did not help that much, I had to uncheck the NR slider.  With lightroom, I had finer control of the noise so that I kept the fine detail while reducting the noise.  I also could use the brush in LR to selectively apply NR which worked much better.
After trying it, I think that DXO does a better job of guessing the corrections to apply, but I much preferred my edits in LR most of the time. 
For a $200 price tag, it seemed badly overpriced, $39.95 might be more reasonable, but I'd probably skip it for that price as well.
Still, someone who did not feel comfortable with using the LR sliders might do OK with it, but might also be frustrated with the tint controls and excessive NR.

Lenses / Re: Need some advise: light sensitive lens indoors
« on: November 10, 2012, 07:27:47 PM »
I am looking for a lightsensitive lens for indoors use.
I have some lenses i.e. 135mm f/2 L that are lightsensitive but very often its focal length is too much.

Personally I like the flexibility of having a zoom when taking photo's indoors since not always I know how much space there is. And, the lens should be easy to handle from size and weight point of view (so my 70-200 f/2.8 is less convenient here)

My budget is max. 1000 euro

The Canon 24-70 MK II L is not an option from pricing point of view. Neither is the Canon 85mm f/1.2 L

I am considering either the Tamron 24-70mm f/2.8 VC or the Sigma 85mm f/1.4
I know I know, I already own the 24-105 but this lens is my outdoors walkaround lens. So I don't mind overlap

Can anyone share his/her experience about the Tamron and/or the Sigma?
And, what would you do?
If you are wanting a low light lens, consider a inexpensive prime lens.  IMHO, f/2.8 is not going to be a extreme low light lens, f/2 barely makes it. 
So, if you want a zoom, add a flash.
Some fast primes that are low priced are 28mm f/1.8, 35mm f/2, 50mm f/1.4, 85mm f/1.8, 100mm f/2.

Software & Accessories / Re: Eye-Fi Card on 7D
« on: November 10, 2012, 07:13:55 PM »
I haven't been able to get it to work.

Does anyone know why Eye-Fi does not make a CF card?
Generally, eye-fi cards were not intended for pro photographers doing large RAW file downloads.  The Wi-Fi connection is very slow, and very frustrating if you have large files to download.
CF Cards are now only being used for a few high end cameras, and as time goes on, we see fewer uses.  Sales for CF would be pretty low, compared to the development cost.

EOS Bodies - For Stills / Re: Extenders with 5d3
« on: November 10, 2012, 06:03:16 PM »
Thanks for the info, I had not realised the 2x would be f11  :-[ any preference between the Canon or Kenko, my instinct is to go with the Canon Mk111 even if it is more expensive.

Alan
One thing to consider is that the Kenko will work with lenses like the 100mmL and the 70-300mmL while the Canon TC either will not mount at all, or only works at certain focal lengths.
I bout a Kenko f/1.4 and it worked for about 20 images and then dies the 2nd time I went to use it.  I did not replace it, just returned it because Canon announced the f/8 firmware and I already have Canon TC's.
I have not heard of reliability issues with Kenko, so it might have just been bad luck.

You have two custom file naming setups in the 5D MK III, its easy to switch.  You can also quickly change one of them for each bracketed shot, but that might get frustrating.
In any event, stack them in lightroom and that will keep them together.

You will be pretty frustrated trying to do this, but some have had limited luck with certain apps

I'd just forget the idea.  Downloading large files will be slow at best.

Lenses / Re: 50mm
« on: November 10, 2012, 12:37:27 PM »
You did not say what you would use it for, or if you would be a heavy duty user or ligh user.  There is not a huge difference in image quality between a cheap 50mm f/1.8 and a $750 lens.  For the most part, you are paying for a wider aperture, improved construction, and faster autofocus.
If you are only going to use the lens occasionally, get the Canon 50mm f/1.8.  However, if you want to use manual focus one of the others will be better, the Zeiss being much easier to manually focus.  However, with manual focus, you run into other issues like the viewfinder size, focus screen type, etc.
Another thing to understand is that lenses perform differently on APS-C and Full Frame bodies.  The Sigma 50mm f/1.4 is optimized for Crop bodies, while the Canon 50mm f/1.4 is optimized for use on FF bodies and has better IQ on FF than the Sigma does. 

Hello,

I would use this lens quite frequently in all situations. I'm looking for a well constructed lens and good quality. I have used the Zeiss and it was great. I have also used the Canon 50 1.4 and it wasn't as good as the Zeiss. The only one I haven't used is the Sigma. I use a 5D Mark II, so I wouldn't go with the sigma since it isn't great with full frame.

Thanks,

littlepilotdude
Are you talking the Zeiss 50mm f/1.4?  It certainly is not as good optically as the Canon 50mm f/1.4, but has a better build by far.  With a wide aperture autofocus lens, its pretty common for the AF to need fine tuning with AFMA for the best results.
Here is a link to comparisons of test data.  The Zeiss has less viginetting, but loses by a lot in the other areas.

Lenses / Re: Zeiss Planar 50mm 1.4 on Crop Body
« on: November 10, 2012, 12:17:02 PM »
50mm lenses typically use a age old optical formula which is not as good as some of the newer formulas using more elements. 
You are paying more $$$ for supurb construction and for the Name.  For manual focus, Zeiss lenses are wonderful to use.
Photozone previously tested the lens on a crop, but it has fallen off their list, probably because of the obsolete camera.
Here is what they say.  "Some years ago we analyzed the Zeiss Planar T* 50mm f/1.4 on an APS-C DSLR and the results were truly impressive there. However, on a full format DSLR the performance leaves a bit to be desired actually. "
As more and more users switch to FF, the lens will become less popular, so its price may suffer, but thats just a guess.
DXO has also tested the lens on many bodies.  You can view the test results and select different bodies to compare here:

Their test data is fine, but their DXO Mark ratings are biased, just as is any rating that tries to give a overall score for a product is biased by the method used to score it.

« on: November 10, 2012, 11:59:20 AM »
There are many opinions as to how to manage images.  Certainly, you need jpeg images to post on the internet.
You can save images as DNG, and there are three flavors of DNG.
However, all the expert professional work flows have one thing in common, backup your files and use keywords rather than directories or multiple catalogs.
Martin Evening, Julieann Kost (educator), Victorie Brampton (Lightroom Queen), Scott Kelby all have excellent publications detailing their preferences and why. 
I'm sure there are many opinions, but readup what the experts have to say, they have establishied themselves as the experts.  Then feel free to do it your own way or modify their method to fit your needs.

Old computer fresh install.  Same deal as the laptop using the same disk
I haven't yet upgraded to Windows 8, I've been planning to buy or build a new PC.  Its tough to build my own for the price of a Dell XPS with i7 3rd generation.

EOS Bodies / Re: got a 5d mark iii offer for 2980, jump in or not?
« on: November 09, 2012, 09:00:57 PM »
If its a local dealer, go ahead.  Right now, the loowest is $2910 from a unauthorized dealer.
Last year, B&H had 10% off cameras and lenses for black friday or cyber Monday.  It was just for a few hours.  There are always Black Friday sales on cameras, but you are unlikely to save all that much.

« on: November 09, 2012, 02:01:34 PM »
I have the 17-40L. Bought mine new some time ago and just recently noticed that all my images are a little soft on the right side of the image at 17mm. The rest is tac sharp.

I've heard others complain about this as well. I plan on taking it in to get it looked at. You may want to check the edges, just to make sure...

Thats a typical symptom of decentering.  You can check it by rotating the camera to different angles and seeing if the problem remains in the same relative side of the image.
