Lenses / Re: 24 f2.8 IS or 28 f2.8 IS ???
« on: December 13, 2013, 08:33:59 AM »
It's funny how those 4mm can make so much difference!

Speaking of mm, those mere 4mm push you about 17% further into "tele" (or better, away from "wide"). In fact 28mm is midway between 24mm and 35mm (it's still closer to 24mm, but a 29mm lens would in turn be closer to 35mm, and would be further away from the middle than the 28mm is - 28.47mm would be the middle lens).

This assumes the "mm" that identify the lens are the real focal length of those lens, which is not.

Software & Accessories / Re: Workflow, what do you do?
« on: November 04, 2013, 10:37:36 AM »
My workflow (personal use) is:
1. upload from card reader to specific folder (eg 2013.11.04 - Event Title XYZ), each within a "year" folder (in each "year" folder there is also a folder with the same name (eg 2013) there the extravagantes images are copied (eg taken with the iPhone and not related to any particular event); if an event lasts more than one day, I prefer to still have  single folder and the initial day is used for the name;
2. synchronize folder in LR so that the new images are imported (and new folders are created) in the catalog;
3. delete images I don't need to keep (flag as reject and the batch delete so I only have to confirm deletion of the original file once);
4. edit (or promise I will) and flag.

So, I have a couple of questions myself.

1. In my "flagged" smart collection I can quickly find (in LR) my favorite shoots. I tend to export (i) all of them as small jpegs to be uploaded into mobile devices/cloud, and (ii) few of them as tiffs to be printed out at the lab. Is there any workflow/trick/IFTTT receipe that could help me to automate the jpeg export/upload? (other than switching to Aperture)

2. Assuming I have a safe backup strategy, which files should I backup to be super safe? Original CR2s along with LR catalog (where I understand all the edits for all the pictures are stored) or a newly created DGN? In the latter case, will each single file include all its specific edits also preserving the original raw?

Thank you

Software & Accessories / Re: Screw-in variable ND filters
« on: July 23, 2013, 02:27:16 PM »
It is a bit on the expensive side initially, but if you plan to buy several lenses you would be better served with the filter holder systems. Personally, my lenses have filter sizes of 58, 67, 72, 77 and 82. To buy the various NDs and CPLs would have cost me more money.

What about step-up/step-down rings. Are they any good?

I use a 10-stop and a 3-stop ND, as needed.

I would also avoid the variND route. Is 10-stop and 3-stop a flexible kit or would you suggest different combination. BTW, how the B+W labeling (0.3, 0.6..) translates into stops?

EOS Bodies - For Stills / Re: How to select ISO (tutorial)

For your specific camera model, you can look here:

Thanks for sharing. Anyone has some data/guess on the 6D? Should I assume it to be close to the 5D mark III (or mark II)?

Lenses / Re: Help me choose 40 v 50(1.4)
« on: July 04, 2013, 03:00:08 PM »
Thank you all for your feedback, I'm glad I re-registered to CR.

I thought that for my specific two questions no more context was required. I was clearly wrong.. I plan to add this lens to 6D w/ 24-105/4. Next in line are 135/2 and either Rokinon/Samyang 24/3.5 TS or Rokinon/Samyang 14/2.8.

I like size, cost and sharpness of the 40, but I think I need something really fast to experiment with DOF.

Lenses / Help me choose 40 v 50(1.4)
« on: July 04, 2013, 08:02:20 AM »
Thanks to the information available in the forum, Pros and Cons of both are clear to me. But I still have a couple of questions I hope you can help me figure out:

1. wide open on full frame, how much I will notice the difference in terms of DOF considering the relatively short focal lenght of both?

2. how much I will notice the difference in term of sharpness (not necessarily wide open)?

Many thanks
