I have a pair of cactus v5 triggers. No ETTL but the price is right. They are less than robust but I have had no problems using them. From time to time my off camera flash does not fire but reseating the triggers/flash sorts this out. If you are on a budget, I recommend them.

My initial tests indicate that the lens is ok. I have to do some more tests but I have to wait for the flu to clear. Thanks again for the advice.

Thanks guys for the sage advice. I am going to do exactly what you have recommended, after I get better.

While under the ravages of the flu, I dropped my 70-200L F4 onto the carpet from my bag. I guess it dropped about 4 feet. What tests do you recommend to make sure it is still functional? If the lens is broken (hopefully not), what are my options? The lens is just over a year old. 

I love it very much and feeling bummed out (the flu does not help matters; I am freezing cold and feel completely out of it which is why I dropped it).

Thanks for any advice.

For what it is worth I have been in the market for a 35mm and tomorrow I am going to buy the Sigma for my 5d2. I have read enough reviews that I am fully persuaded that the lens is worth it and that spending more money on a Canon 35L would not be the correct decision:

$899 vs $1300+

Maybe I will regret it but I am hoping I won't. Will be up at the store by 8:30 for its 9:00 opening.

Not sure what level or type of book you are considering, art, composition, technique, lighting?

I am less interested in technique per se and more interested in composition. In particular, I want to explore the ideas informing high art photography and how the image works on the mind. I just picked up Stephen Shore's book which for me is expansive. Sontag on the other hand I find to be trite but perhaps she just annoys me and I am being unfair.

Thank you very much for your responses.

I should add one book to this list: Vivian Maier: Street Photographer.

I lit upon this book by accident sitting on a friend's night table. I find it remarkable.

Not sure if I am allowed to link to it but here is the site with some great examples of her work:

Then, if you want to challenge yourself, pick up Susan Sontag's On Photography and Roland Barthe's Camera Lucida ...

Each can be read over and over again and each time you will learn something new. And, not a single one talks about f-stops, ISO, noise, bokeh, crop factor, or any of the other drivel that bogs people down. They are all about vision and understanding this fascinating and addictive craft.

Excellent recommendations. Thank you.

I am an avid reader and I was just wondering which books you have read that helped you further your understanding of photography, whether from a technical or a compositional angle.

Myself, I recently discovered John Szarkowski's "The Photographer's Eye" and I have been studying it slowly. This got me to thinking that there must be other great books which I have not yet discovered. I also like Edward Hopper's paintings very much and I saw its application to photography as a higher art form not realizing of course that this is a well trodden road.

I like your photographs especially your black and white work. I would seriously consider starting to work with off camera flash and spend your winter perfecting throwing light on to your subjects. I might even buy two flashes (since money is not holding you back) and get both off your camera. I bought a set of Cactus V5 triggers because the price was right and they seem to work ok for manual work.

My impression is quite good regarding the Sigma 35 ...

Thanks for the review.

Have the 5d3 and 35mm 1.4 Sigma and can use all the AF points like my L 2.8 glass can on the camera. All 45 cross and 61 points are usable.

What are your impressions of it?

I think it is important to distinguish between data availability and data integrity, since some of this discussion is conflating these two principles. RAID, for example, provides data availability but it does not provide data integrity as does, for example, off site backups.

Think about it this way. If you build a mirrored pair of disks and copy all of your photographs to the raid set, you are still at risk of data loss; it is easy to accidentally delete a photograph and the raid set will not enable you to recover it because the data will be deleted from both disks.

If you want both data availability and data integrity then implement RAID (raid 1, raid 5, etc) *and*  then off site backups (off site here defined as media that is not in the same location as your raid set).

In short, you need to back up your data even if you are using RAID. It is a serious error to think that raid provides data integrity.

In my view it would be better to simply not use raid but copy your data daily to different media since data integrity is probably more useful for most people, but of course not all. This is what I do on a regular basis. I have one disk holding my photos and two other disks containing backups of that same data (I am paranoid). If my main disk fails, I am guaranteed of not losing any data and I perform incremental and full backups using these two disks.

Has anyone tried this on a 5dm2? I am a little nervous that it might break my camera but some of the functions would be super useful. Any advice appreciated.

Thank you.
