Software & Accessories / Re: Adobe Announces Cloud-Based Lightroom CC

The direction Adobe is going in is becoming less and less useful to me.  Most of my photography is wildlife done in remote areas of the world where electricity is only available occasionally so you can guess what my access to the "cloud" is!  Because of the slowness of LR, I already use PhotoMechanics for downloading and culling my photos in the field and during my recent 3 weeks in Madagascar I switched from LR to Canon's DPP for converting all my RAW files.  I must say that, although I like all the options of LR, DPP does a MUCH better job of noise reduction, shadow detail handling, etc. of the Canon files.  I then exported the files as TIFFs to LR with all the original Metadata saved for further adjustment.  If I were more fluent in PS, I would have used it instead of LR but at this point I can still do things faster in LR than PS.  I can see ultimately just eliminating LR from my workflow.  Of course, I will be wedded to Canon in order to do this so I have to watch how things are headed in their mirrorless/lens future, etc.

I use Lightroom every day for my job, but my organisation will only use stand-alone versions...

Lenses / Re: 70-100mm VS. 100-400mm Questions?
« Last post by AlanF on Today at 04:25:14 PM »
It isn't just the distance to the subject, it is the relationship between the differences between the position of the photographer and the various items within the image.

^ My 6 y.o. would probably say the same, and there is nothing wrong with it. IRL it's actually much simpler and covered in 8th grade physics (in my country) and relies on basic geometry
As you can see from the picture, the distance between two projected points depends on the viewing angle: wider the angle - more apart the projected points. Assuming you're framing the same subject, only the distance will affect your angle (and perspective distortion).

This is probably a better article https://en.wikipedia.org/wiki/Angle_of_view, but I was referring to the term "compression", and posted a different link mentioning compression.

The diagram you have downloaded from wikipedia is inconsistent with the laws of refraction. It has rays passing through the lens unrefracted and they don't even go though the centre of the lens but intersect in front of the centre. Any 8th grade student who has the minimum of knowledge about refraction would know that the rays would be bent inwards by the front surface of the lens and outwards by the rear surface. A simplified diagram would at least have them going through the centre.

Lenses / Re: 70-100mm VS. 100-400mm Questions?
« Last post by Besisika on Today at 04:03:47 PM »
I'm fairly new to photography.

1. I'm wondering, why not just get one long lens like a 100-400mm and use it instead of the 70-100mm if I do not need focal lengths less than 100?

2. How is the 100-400mm VS. a 70-100mm for portrait photography?

Thanks.
I don't see any difference between 135mm at 5.6 shot on 100-400mm and 70-200mm. Maybe there is but I don't see it.
Both sharp at 5.6 - 11, both have IS and both allows you for 100-200mm
When shooting in studio you mainly shoot at 5.6-11 anyway. Outdoor, background separation depends mainly on the subject to background distance so if you like the look of 5.6 there is no difference between the two lenses.
If you intend to shoot wide open, for similar background blur, then yes the two lenses are totally different. One achieve that blur mainly through F-stop (2.8), while the other through compression. That affects not only the amount of light needed but the working distance as well. But if you want a specific F-stop at a specific focal length (ex 135mm 5.6) both lenses should do the job equally very well.

For portraiture though, I prefer a prime because of weight. Bringing up and down 500 times within 2 hours a camera+ lens has an effect on your health.
So for the same working distance and F-stop I prefer a 135mm or 200mm prime (indoor with available light: 85 1.2). I bring only the 70-200 when I expect a rain, snow or dusty environment.

You would see big difference between the two when you incorporate ambient light. The 100-400 will give you only 5.6 and as a result you might need a bunch of that ambient light. This becomes obvious indoor.
Outdoor, 100-400 maybe better if you use an ND filter instead of HSS, because you start right away from 5.6. On overcast day, you may not even need any ND. During bright sunny day just a few stops while the 70-200 requires 2 stops more and your camera might have more issues focusing. When using HSS, the 100-500 needs HSS only during bright sunny day.

Finally, when shooting in crowd (not a typical portraiture but becomes more and more popular - cosplay, zombie walk, fashion show, etc) you will need an F-stop wider to knock out the background faster under the same working distance and again prime wins.
Zoom would be important only when you shoot without the ability to zoom with your feet (example fixed position when models are posing by themselves for many people to shoot at same time - fashion event, sport event, etc)

Hope that helps,

Caveat emptor, yo:

"Focus accuracy is of course quite important and this lens is also a decent performer in this regard, delivering roughly 90-95% of images in-focus when using the center AF point. Peripheral AF point performance did not fare as well, with this lens exhibiting noticeable front-focusing from both EOS 5Ds R models it was tested with."

The lens doesn't have much value to me because of unreliable AF. But imagine if Canon releases an EF-mount mirrorless that would be relying on DPAF, and out of sudden all those focusing issues become non-existent! If it happens, the first thing I'm going to do is to buy the Sigma 50A :)

It doesn't have unreliable AF. I recommend going into a local shop and trying it on your camera body. And read some actual end user reviews like found at B&H or Adorama.

By all intents a very, very good lens. Especially when considering the price. Like I encouraged Mr. Sanford to do, check out Dustin Abbott's review too.

Again, we lack a great AF hit rate database to go from and Mr. Carnathan did not state a test method this time, but a 90-95% hit = 5-10% miss rate... for an f/2.8 lens... through the center point only.  I'd expect some percentage of AF whiffing with a fast prime, but f/2.8 has considerably more working DOF to get by.  This is not encouraging at all.

Also: "Of interest to some is that subjects change size a noticeable amount during focus distance adjustment. Photographers using focus stacking techniques, videographers pulling focus and anyone very-critically framing a scene will want to be aware of this common issue."

And there's subsequent commentary on focus breathing at play.

I suggest you also check out Dustin Abbott's just completed review of the same lens. He did some comparison shooting with the Canon 24-70mm f2.8L II and the just released Sigma Art 24-70mm f2.8 OS.

Very interesting results. With some real world emphasis. And he did source 2 different copies of the Tamron - one from a Canadian source and one from a US source...

I can see a remote camera being set up for wildlife with a better beamer type flash on camera then the ST-E3-RT should be able to be used to trigger them both, but I don't think they can be used like that.

But my hähnel wireless remote trigger will do that just fine.

So will the CamRanger  ;)

So will the RS-80-N3 and the ET-1000N3 I got when we didn't have better options! Before that I had a 30' pneumatic plunger style cable release. Oh how times change..........

I wonder how the coma is on this lens. Any reviews that mention coma or astro imaging??..I could only find the ePhotozine Review, which was very positive but did not mention Coma performance as far as I could tell.....

Looking at the MTF chart, I would be very surprised if "coma" is well corrected beyond 10mm off-axis.  The solid and dashed lines begin to separate quickly after 10mm.  This is a bad omen if you are hoping for pinpoint stars out to the corners.  Besides, Zeiss is not going to come out with a lens that beats their Otus 28mm for $2400.  The Otus 28mm MTF shows the separation of the solid and dashed lines beginning around 15mm off-axis which  is about where stars begin to show "coma" in starscapes.
