PowerShot / Re: Canon S110 vs S120
« on: January 06, 2014, 04:49:10 PM »
This is a good review of the S120 giving high marks for it's touch screen focusing, perhaps the most important upgrade to the S110.  The S120 is compared favorably to the Sony and Lumix given it's price point and pocket-ability.

Lenses / Re: Portrait: 85mm 1.8 or 100mm 2.0

I find the 85mm is more versatile for portraits unless you are doing only head and shoulder shots and even then it's quite easy to crop a bit with a 5D3 and get the 100mm eqivalent.

Lenses / Re: Canon 24-70 ii in stock at Onecall and PC.Nation

When the 5D3 first became available, I ordered it and a 16-35L lens from One Call.  They shipped each seperately Fed Ex requiring a signature which is One Call's policy.  When the 2 boxes arrived in town, it took an additional 3 days to get me and the boxes in the same place at the same time.  A Fed Ex nightmare which could have been averted if the boxes had been sent to my office and not my residence.  Lesson learned.  One Call was great to work with though.

This morning I noticed Spammer listed the lens in stock and I purchased 1 of the 3 units they were expecting to receive this afternoon.  It was shipped this evening and the lens is now again listed as backordered.  I believe today's was the fourth shipment they have received in the last few weeks so they seem to be getting a steady supply.  Very friendly and helpful staff.

Lenses / Re: Roger at LensRentals impression of 24-70 II

Wow those are some seriously impressive results, sharper than the 24 ts-e and the 70-200@70mm?!  I expected it o be good but damn that's outstanding.

I pre-ordered from B&H one month ago so I probably have little chance of catching the first wave of deliveries.  This is the same scenario I had with the 5D3 in the Spring.  However I was able to cancel my pre-order when a fellow forum member mentioned 5D3s were available on the West coast - so if you find availability please share.

EOS Bodies / Re: A question about dust...
« on: September 03, 2012, 07:20:51 PM »
My 5DII did get a fair bit of dust, and required cleaning every couple of months.  I've had my 7D for longer, and it's never needed cleaning - I expect the smaller sensor is better for that.  The 1D X has an improved cleaning system compared to the 5DII and 5DII (which are the same), I hope it does better than the 5DII...

Which 5D models have the same cleaning systems?  So far after 5 months of heavy use my 5D3 remains clean.

Lenses / Re: 200mm 2.8L II
« on: September 03, 2012, 07:13:41 PM »
I bought the lens 8 years ago to capture high school sports.  It was excellent on a crop body (20D & 40D) for indoor volleyball and Friday night football under the lights.  Never missed having to carry a 70-200 which I figured would be at 200 mm 98% of the time anyway.

Yes thanks so much for sharing your research.  Have tried cleaning the sensor with a Lens Pen?

Great!  So looking forward to my pre-order being filled and the German rumor proving incorrect.  I am tiring of looking at the world with only a 16-35 mm and a 70-300 mm perspective.

EOS Bodies - For Stills / Re: Black specks on 5D Mark III
« on: September 02, 2012, 10:21:19 AM »
If the specks dont' show up on photos and the sensor's clean, it's likely dust on the focus screen, in front of the pentaprism.  Unless the dust specks REALLY bother you, try to ignore them.  If you are OCD, do NOT try to clean it with anything other than dedicated focus screen cleaning product/swabs such as:

I used a Q-tip and lens cleaning fluid on my 5D3.  Are you saying the focus screen can easily be damaged?


The focus screen is somewhat soft plastic with fine grooves on the surface, which is much easier to scratch and/or leave swirl marks.  if Q-tip with lens cleaning fluid was used lightly, it should be OK, but if one was really trying to remove a tough speck by pressing harder, it would leave marks.


As it turned out the Rocket Blower did the trick and the Q-tip/lens fluid was a waste of time.  But how do you folks feel about cleaning the 5D3 sensor with first the Rocket Blower followed up with a Lens Pen if need be?
