Great Sigma 50 pix folks!  I especially like the self portrait.

It looks like this thread could use an update.  Here is one I took in the Portland train station with the Sigma 50 at F/2.0, 1/160, ISO 400, 5D3.  Minimal crop, minimal post.

Let's see some more Sigma 50 images!

I've used a card reader ever since I first went digital many years ago.  I've gone through a lot of them.  I hate waiting so I always get the fastest card reader I can find and try to use fast cards as well.  Never had any problems with bent pins, but I do try to be careful when inserting CF cards.

The SATA card readers were my favorite until USB 3.0 came out.  That was around the same time that I upgraded my computer case and could no longer use the SATA reader that fit into a floppy drive slot.  Most new cases don't make any provision for floppy drives and all the drives that fit in 5.25 inch optical drive slots were still USB 2.0 the last time I checked.

I am now using this Kingston USB 3.0 reader.  I haven't done any speed tests, but it seems pretty fast and I haven't had any problems.

I tried a couple of USB 3.0 readers from SYBA that ran really slow.  Some sort of defect I guess.  Sent the first one back and the replacement was no better.

Here is a recent shot with the 85mm F/1.8.  I stopped down a little to maintain some detail in the background as context for the photo.

Data:  F/3.5, 1/250, ISO 100, Canon 5D3, minimal crop.

I love the 135L!  Here's a shot from today using a 5D3.  1/640 hand held at F/2.8, ISO 100 on a cloudy day.  I wanted to leave some background detail so I did not use F/2, that pretty much obliterates the background.  This lens benefits from a tripod, but I did not need that much sharpness on this shoot.

Thanks for posting the photo!  I'm going to be more careful with my Mark 3 from now on.

It does look like the frame of your Mark 3 has significant corrosion.  Maybe that's where the water got in?  Perhaps that joint between the back panel and the frame might be a good place to try to add some sort of sealant if you were forced to use your camera in damp conditions.

One thing, though, is if you bring the camera quickly from a hot/humid area to a cold (e.g. aircon'ed) area. That would make the humidy condense quickly, and possibly creating shorts.

this sounds like a much more likely scenario. it is quite common for this to happen on weddings moving from hot exterior conditions to air conditioned interiors.

Hmmm... isn't that backwards?  Water usually condenses on my gear when I bring it into a warm building after being outside in very cold weather.  Did you happen to take the camera on a ski trip last winter?

Sorry to hear about your problem!

My 100 2.0 has been sitting unused for a long time, since I have the 85 1.8 and the 135L.  But last weekend I found a great use for it:

(this was at F/2.8 and 1/160, hand held, 5D3)

It's a great lens for shooting hood ornaments at a classic car show!  LOL

There are a few more shots from the Concours d'Elegance on my blog if anyone is interested:

Pricewatch Deals / Re: Announces

The prices on the lenses that I am familiar with are not that great compared to what you can find on Ebay or Craigslist, but you get a real warranty and return privileges.  Plus the Lens Rentals crew apparently tests the optics on each lens, so I'd say overall it looks like fair prices.

I do wonder why they sell off these lenses that are in apparently "rentable" condition.  Do they expect them to start malfunctioning after a certain amount of time in use?

My Canon S90 is now my hiking camera.  But I'm old and can't climb mountains like I used to.   Frankly, the shots I got back in the day with a film SLR were never that compelling.  Most ended up being snapshots of my fellow backpackers/climbers and that did not need a nice camera.

any tips on setting white balance on shooting waterfalls?

AWB and correct it in post ?

Grey Card?

my ND filter give me that nasty magenta colour

Shoot RAW and click the color balance eyedropper on an area of white water.  That will get you pretty close.

I've been shooting waterfalls for 45 years and I live in a waterfall rich area. (Near the Columbia River Gorge.)  I shot them obsessively until I switched to shooting pretty women.

The waterfalls around here are mostly in canyons that never get good light on a sunny day.  ND filters don't help, because you have too much contrast between the white falling water and the dark rocks and trees.

I simply wait for a cloudy day or I shoot early in the morning before the clouds burn off.  If I am travelling some distance to photograph a particular waterfall, I make sure I understand it's geographic orientation.  Sometimes with that info, I can make an educated guess as to when there will be good light on the falls, like just before sunset, for example.  Shoshone Falls near Twin Falls Idaho is a good example of a waterfall that faces West for a nice sunset look.  It took me two visits to figure that out!  Sometimes if you wait until evening when there is no direct sun, you can get the dim low-contrast light that you want.

The key thing to remember is that every waterfall is different.

If you are travelling and only have a brief opportunity to shoot a particular waterfall, you are often screwed by the nasty bright, contrasty light.  If you are visiting for the first time, you probably won't know what lens is best, so bring all your wide angle lenses.  It might be helpful to study photos of the particular waterfall on the net to see what light and what shooting positions others have found attractive.

If you happen to get a good cloudy day you are golden.  Set your shutter speed at 1/10, your ISO at 50 and you should have a small enough aperture to do the job.  You won't need a filter unless you want to turn the water into fog, but that's up to you.  Don't be afraid to chimp the LCD screen to get what you want.

That's my method and I'm sticking to it!

More dynamic range would be appreciated.  And focus points farther out from the center of the frame.  I'd like the ability to make the focus points light up whenever I wanted for low light photography.

Lenses / Re: Focus Issues with EF 24-70mm 2.8 usm
« on: July 19, 2013, 12:11:41 PM » had a good article on these lenses:

I never bought this lens because my Tamron 28-75 was doing the job for me.  I did rent one from Lens Rentals to see what I was missing and it had absolutely horrible focus shift as you zoomed through the range.  I assume that copy was worn out as described in the article above.

Tamron 28-75 2.8

Agreed, this is a great lens for someone who has switched to full frame, but doesn't have the budget for L lenses.  I keep mine around for backup.

I also have a friend who shoots lots and lots of people pix with this lens on a 7D.   Its a nice portrait lens on a crop body. :)

Third Party Manufacturers / Sigma Service :)

Like a lot of photographers who use 50mm F/1.4 primes, I often wonder if it could be a little sharper wide open or focus a little more accurately.  While I was getting to know my new 24-105 L zoom last month, I decided to send my Sigma 50/1.4 in to Sigma for a little TLC under warranty.  I've had it for about two years.

On the repair request, I said that it was not as sharp as I wanted wide open and it did not focus as accurately as my Canon lenses.  I figured that would challenge them a little.

I got the lens back exactly two weeks after I sent it, which means they had it in the shop about 3 working days, by my estimate.  Pretty impressive.

The service invoice says they "adjusted af data"

If there is any improvement in performance, my methods are not adequate to detect it, but I do feel better knowing that the lens is properly calibrated. It's a confidence thing, you know.

This is still one of my favorite lenses, along with the Canon 85mm F/1.8.
