I am a relatively new photographer, having been at if for only a few years. I chose Canon gear when I finally took the plunge into DSLR. I am an avid hobbyist now, and love everything about photography, from the gear, to the science, to the art. I spent years reading about the technology and photography theory, so I am very well versed in the technical aspects of photography. My artistic skills are moderate, but improving. You can see my work @ the following sites:

My interests lie primarily in nature photography:

  • Birds
    • Songbird Setups
    • Shore Birds & Waders
    • Raptors
    • All others
  • Astrophotography
    • Moon
    • Wide Field
    • Deep Sky
  • Landscapes
  • Wildlife
  • Floral Macro
  • Insect Macro
  • Abstract

I currently use the following gear:

  • Cameras
    • Canon EOS 7D
    • Canon EOS 450D (Rebel XSi)
  • Lenses
    • EF 16-35 f/2.8 USM L Wide

comment Canon 50mm lens: f/1.2 L or f/1.4? Alternative brands?
Thanks for all the insight. For a 50mm lens, I will get either the Sigma 50mm f/1.4, or maybe a Zeiss 50mm manual lens, and save the rest of my money for a TS lens. I think I'll get far more out of say the 24mm L TS-E than out of the 50mm f/1.2. I don't think half an extra stop of light or some better sharpness is really going to do that much for astrophotography. I do agree about the larger sensor of the 5D, and one of my reasons for getting a full-frame body is to finish off my astrophotography kit. Wasn't aware that it was 2.56 times as much light though...intriguing statistic.

comment How well do tilt-shift lenses work for nature/landscape photograhy?
Thanks for the info. :) Very interesting point about the 17mm and filters. I've read a couple reviews, but the thought about filters never even crossed my mind. I am a fan of Lee filters, so I really wouldn't want to lose that capability. Guess thats why a few people have said they opted for the 24mm over the 17mm.

@Matt: Ah, he used an old MF lens. That definitely sounds like an intriguing option! At the very least, I can experiment with TS and get the hang of it for a few hundred before spending a few thousand on a true TS lens. Any ideas where I might be able to find some MF lenses for sale on the net?

comment How well do tilt-shift lenses work for nature/landscape photograhy?
Thanks for the info. It sounds like a TS-E lens does indeed bring the same basic capabilities of a large format view camera to smaller formats. Out of curiosity, why did you sell the 17mm, and keep the 24mm? I guess I would have thought that the 17mm would have been nicer for wide landscapes. How does the 24L TS-E do for landscapes?

comment How well do tilt-shift lenses work for nature/landscape photograhy?
@Matt: Regarding a DIY TS lens...what about image circle size? You need a larger image circle to accomodate the extra movement, and keep the sensor inside the circle. I can't tell exactly how that works from the article you linked. With the TS-E 17mm, the image circle is something like 62mm in size, which is quite a bit larger than 43.7mm of a normal image circle.

@Shizam: Yeah, thats what I'd read when learning about large format view cameras. Have you used a TS lens on a DSLR? Any insight?

comment What is the dynamic range comparison between SLR, DSLR, and point & shoot?
@Reid: I think the difference is minimal at best. I also think it would be nice to have a go-to thread for DR questions, rather than having them be answered individually each time the question crops up. Digital in relation to film, human eye, computer screen, etc. were all asked in the original question. That covers this one as well.

comment How can I avoid overwriting original images after editing in Lightroom 3?
@Alan: Exactly! With lightroom's organization and searching tools, it works best if you import all of your photos into a single folder (or perhaps a few folders in a flat structure.)

+1, plus one! Finally! Someone has offered up a reasonable real-world estimate for camera dynamic range. The average DSLR has about 5-9 stops of real-world performance. :D

As Karel pointed out, this is a duplicate of a previous question. Barring significant objection, I will either close this thread as a duplicate, or merge it with the thread linked by Karel, as the two are quite literally duplicates.

comment What is the dynamic range comparison between SLR, DSLR, and point & shoot?
I am a bit wary of the accuracy of DXO-Mark. It says my Canon 450D has 10.8 EVs worth of dynamic range. I know for a fact that is most definitely NOT the case. With ETTR and some very meticulous manual adjustments to aperture, shutter, and ISO, I can MAYBE get 9 stops worth of real-world dynamic range, but normally I get about 7-8 stops. Sometimes I think these scientific measurements mislead potential buyers, as real-world performance in a photograph as observed by the human eye rarely approaches what can be scientifically measured with non-human algorithms and devices.

comment What is a good all-purpose, single-lens choice for a 7D, to take trekking in the Himalaya?
We seem to have a rogue down-voter in our midst. If you down-vote, please tell the Answerer why. I gave this a +1, as I think the Tamron 18-270 is a great option. It offers a very wide focal range that should allow both wide-angle landscape and telephoto wildlife shots.

comment How well do tilt-shift lenses work for nature/landscape photograhy?
I'm not sure its just about lines and perspective. In landscape/nature, its more about focus plane (tilt). For example, you could tilt up just a tad to get foreground in clear focus without losing your distant focus (blurry foreground happens a lot.) There are also close-up or closer focal plane options where having more freedom with the focal plane allows greater creativity. I understand why large format view cameras (used heavily in pro landscape photography) have these types of movements...I am jot sure if a TS lens for a full-frame digital offers the same capabilities that justify cost.

comment Canon 50mm lens: f/1.2 L or f/1.4? Alternative brands?
Regarding the 5D, I am actually waiting for the 5D Mark III. I've been on the brink of buying a 5D II a few times, but with the Mark III just around the corner, I could never bring myself to actually purchase it. I do believe the orig. 5D is indeed a stellar body, I've seen some amazing photos from it, but I love to blow my photos up to HUGE size with lots of detail...so image resolution counts. The 5D III will be bought regardless. I am seriously considering the Sigma 50mm now, as in comparison with the Canon 50/1.4, it seems to perform very well. Thanks for the tip!

@Sarah: Glad you found it helpful. :) Lightroom is pretty disconcerting at first. I didn't even like it much for about a month or so. I finally sat down with it one day and explored every option and tool, worked a bunch of photos, and learned how to use it. Once you understand its design, its workflow, and how it organizes its catalog and your images, it is a pretty fantastic tool. I do highly recommend you get to learn how it manages files. Its catalog, where it stores original images, where it stores presets, and how it stores your edited images.
