EOS Bodies - For Stills / Two 6Ds: two different focus screens.
« on: March 19, 2014, 05:53:38 PM »
Hi all,
I like to do a lot of creative work with my f/1.2 lens, as well as work in low light with my f/2.8 zooms.  I also do events.

I have two Canon 6D cameras. Right now, one has the stock screen installed - while I recently installed the EG-S in the other.  I installed the EG-S because I felt the viewfinder was not giving accurate depth of field with f/1.2 as it was difficult to manually nail focus (or confirm the AF hit).

All of my lenses are f/1.2-f/2.8 in speed, but I feel the f/2.8 lenses are quite a bit darker (somewhat expected) with this new screen.  Not dark to the level of not being to compose, but might make it tricky in a dim event where I am using flash.

BUT, the f/1.2 lens seems way easier to confirm auto focus and also manual focus with the EG-S.

My question is, does anyone else here have two 5D/6D cameras with a different focus screen installed in each?  They seem to each have benefits.

So, I was thinking it made sense to have one 6D with the EG-S (for 1.2-2.0 lenses), and the other with the stock screen (for low light f/2.8 zooms).  Anyone else setup like this?

EOS Bodies - For Video / 6D+VAF5D2 vs 5DIII for video?

Which would offer better video quality, a 6D with the above moire filter, or a 5DIII without it?

Lenses / Refurbed lenses and sharpness
« on: November 25, 2013, 09:56:07 AM »
Hi all,
So while I have bought refurbed bodies, I've never bought a refurbed L lens.  I can see why someone would return a body because it did not meet their needs, but returning an L lens I would find less likely for this reason as its pretty clear what a lens is able to do upfront.

Reason behind my train of thought is the below:
1) Canon refurb stock to my knowledge is generally customer returns in the 30 day period or dealer demos
2) I've heard lots of people who will do sharpness tests with brand new lenses and return them if they do not match some of the reference tests online.  Or sometimes they will order multiple copies and return the less sharp ones.
3) Most of the time due to copy variation less sharp copies are generally considered in spec (i.e. look at lensrentals data), and thus Canon would not adjust it
4) Thus, when buying a refurb lens and thus a customer return, there might be a higher probability you would get a less sharp copy than if you bought new

Is this reasoning crazy, or do others agree? :)  I do know many people are happy with refurbed lenses, and I am not talking about getting a lemon here, just a lesser chance of getting the brightest bulb of the bunch.  I've also heard quite a few stories of people getting refurbed lenses with a lot of dust inside, though it is unlikely that would affect image quality.

Lenses / Wow lens filters are hard to sell!
« on: November 23, 2013, 04:55:43 PM »
I have a couple of spare lens filters on Amazon from previous lenses I sold. They are all B+W XS-Pro MRC Nano 007m Clear filters - good stuff!  In 77mm, 58mm, 52mm... But they won't sell for weeks even though I have the lowest price and they are in beautiful shape!

I'm really surprised, has anyone else had difficulty selling lens filters they don't use anymore?  Or is this just an unpopular model I am using?  IMO it is the best model for the cost, but perhaps because they are costly filters they don't sell much?  I know you can get a lens filter for a fraction of the price, but usually you get more flare, loss of clarity, and color tint with those cheap filters - are people not aware of this in general?

Lenses / Owning both EF 16-35mm & EF-S 10-22mm
« on: November 15, 2013, 05:50:23 PM »
So I have both a FF and crop camera and generally carry both in the kit.

In terms of UWA lenses, I currently only own a EF-S 10-22mm because the distortion appears quite low @ 10mm compared to 16mm at FF from online comparisons I've seen, likely largely due to the nature of crop.

I do appreciate the greater speed of f/2.8 on the 16-35 and realize a lot of the distortion can be cleaned up in post, but I am thinking the 10-22 would still be nice to have for shots that need less post cleanup...  Maybe spend the money I'd spend on a 16-35 on the 8-15 fisheye instead for intended distortion.  Or perhaps a 24mm 1.4 where the speed would be more noticable in reducing DOF.

Anyway, what are thoughts for those that owned both on merits of EF-S 10-22mm vs. EF 16-35mm f/2.8 II?  Let's assume the 10-22 would be mounted on a newer APS-C like 70D vs. 16-35 on 5DMKIII.  I am tempted to sell the 10-22 for the 16-35, but I am not sure it would really be a clear upgrade due to the distortion differences.  If its not a clear upgrade, it would be hard for me to justify the price given my dual kit.

Comments?

Lenses / Lens condensation paranoia
« on: November 15, 2013, 05:07:17 PM »
Condensation is a bit of a topic of paranoia for me, mainly because of nightmares of lens fungus as a result of the moisture.

Question: If one were to shoot in say, 15deg F for some time, then bring the lens into a 70deg F environment while it is in a zippered (but not airtight) camera bag, would condensation form on the lens inside the zippered camera bag if it stays in there for 20min?  Should I worry less about this? your thoughts? thx ;)

Lenses / The future of Canon L primes
« on: November 09, 2013, 01:59:41 PM »
Hi all,
Was curious if anyone saw any patents or info that might imply some of the L classic primes might have an update in the pipeline.

For instance, maybe adding IS to the 135 f/2?  Or correcting some of the focusing issues some have with the 50 f/1.2 (I don't have personal experience with this)?

We have some of the consumer lenses coming out with IS and all new optics, and while the L primes are fantastic, one might wonder if they could be even better with new designs (as we have seen quality improvement with new designs of L zoom lenses and consumer primes). 

So anyone see any hints of updates of the classic L primes, or no?  Just curious :)  Note these updates might include IS, increased sharpness or focusing, etc...

EOS Bodies / 7D2, 6D2, 5D4... USB3?
« on: September 29, 2013, 08:40:32 AM »
Hi all,
As many I am sure a common way to grab files from your camera is plugging the USB cable into your computer.  Of course, this is much slower than using the SD card directly due to the slow speed of USB2.

BUT, there is now MicroUSB 3.0 which is extremely fast.  Anyone hear anything about this being a feature for future canon pro bodies? Thx :)

Lenses / Why pick 70-200mm f/4l IS over 70-300mm f/4-5.6l IS?
« on: August 25, 2013, 03:09:08 AM »
OK,
Given one would benefit from the extra range-
So from what I've read the 70-300mm is as sharp as the 70-200mm f/4 IS through 70-200 at the minimum, perhaps even further out.  Also, while the 70-200mm is f/4 constant, again my understanding is the 70-300mm is f/4 up to 200mm.

So, even if the 200-300mm range is ever so slightly less sharp and is also f/5.6, since the overlapping range between the two lenses is basically the same I am not seeing any disadvantage with this lens vs the 70-200 f/4 is... Thoughts?

Lenses / Chances of EF-S 17-55/10-22 replacements w/ 7dmk2?
« on: August 22, 2013, 12:50:48 PM »
Hi all,
I currently have a 650D and I want to expand my lenses for it.

I actually plan to buy a 7DMK2 when it comes out, but that is some time off.

My question is:
1) Do you think the EF-S 17-55mm IS USM and EF-S 10-22mm will be replaced around 7D launch?  Both are on the older side of available EF-S lenses.  Then again, both are awesome... Only improvement I could see is even further refining optics on both and maybe adding IS on the 10-22 even though its not necessary at such a wide angle.  BUT, still since these lenses are still quite expensive I would be a bit miffed if they were replaced with significantly better versions in 6 months.  Thoughts?

2) Is it possible they might make the EF-S 17-55mm IS USM a kit lens for the 7DMK2?  I don't see the 18-55mm IS STM quite being up to par quality wise with a camera that will likely be the quality of the 7DMK2... If that happens, odds are it will be much cheaper than it is now.  I could actually see it happening, similar to what Canon did with the 24-105L IS USM.

So, just wanted to get some opinions on this.  I really want to expand my artistic possibilities now, but on the other hand if it is likely these lenses are getting replaced in the near future I might just make due and wait.  I realize there is nothing wrong with either of these lenses and they are both fantastic, but I always like to get the best value for my money - so if the value drops significantly in 6mos due to new models, I might have a bit of buyers remorse.  Thanks :)
