The Official Photography Thread - Vol. 3

DJ MAC said:
Wow. I started reading this thread from the first page (YEA the first page!) months back, and I've finally caught up with you guys. I've been into photography (still very amateur, far from a Pro haha) ever since my early teens, before I joined this site. So many great eyes in here, so much great information, so much talent! I'm getting back into the hobby and picked up a mirror less Canon to have with me on the go. I'm not anywhere near the level of some of you guys in here but anyways a few pics I've taken:

Harbor East. I miss BMore here and there.
 
I feel like pros will say they want 2.8 and hobbyists and casual photographers will be fine with the 17-40 f4 since it's $739 after the rebate right now.

Took a nice ride to Bear Mountain on Sunday. Unfortunately I didn't have time to walk around and shoot.

Here are some quick ones.

#unrelatedbutrelatedi just happened to be reading this:

http://admiringlight.com/blog/full-frame-equivalence-and-why-it-doesnt-matter/

and one of things mentioned was the relation of lens size to the f-stop number, where any given f-stop is equal to the focal length divided by the actual size of the opening of the given aperture so that "If a 50mm lens has a maximum aperture of 25mm, it would be an f/2 lens. (Focal length/aperture = 50/25 = 2)." this i'd imagine is why most zoom lenses don't have constant or very large apertures? not only would lenses of that sort probably be very expensive to make but they'd be massive as well. it also explains a little bit on how the different sized sensors absorb light, super interesting...

Sigma makes an 18-35mm f/1.8 that retails for $799 which kind of changed the game, however, it's only for cropped sensor bodies, so I don't know how that logic would apply.

yea i was trying for figure out how that formula works out for zooms because for something like the above mentioned @18mm f1.8 the aperture opening would be around 10mm and @ 35mm f1.8 the it would be around 17mm, and that lens seems pretty large considering it doesn't cover much range and it is for a crop sensor (which in theory allows for smaller lenses than full frame?). according to that site it applies to lenses irrespective of the format size, the amount of light a lens allows doesn't seem to differ no matter what body its on (but it seems the size of the image it projects does change)...i thought it was perhaps semi-related & interesting nonetheless

Well I always relate larger f-stops for low light and bokeh. Not that you'd get a proper bokeh with these ultra wide angle lenses anyways but you still would want to shoot low light shots. I guess that is why it makes sense to have an ultra wide at f/4 and to price point it cheaper since there is the more expensive f/2.8.

Landscape and architectural photography. Need everything sharp rather than having a shallow depth of field. That would be my guess.
 
Does anyone use a DSLR and one of those nicer P&S?

Do you find yourself using the latter more often just because of it's size/portability?

I was considering picking one up .. but most of them seem to be at a pretty high price point and for that money I can pick up some new glass ..

I'm currently using a canon 7D and a Sony rx100m2. I use the Sony rx100m2 for those occasions where a DSLR isn't allowed to be brought in, such as most concerts. Otherwise, if a DSLR is allowed, my 7D comes with me.

I really wish I knew about the release of that new canon 10-18 f/4.5-5.6 a couple months ago. I would have held back on buying the canon 10-22 f/3.5-4.5. I would have saved a couple hundred bucks. Although I am pretty happy with the lens so far.
 
Also look up Serge Ramelli on YouTube. I only watched 1 video but I liked it. He seemed like he would be helpful with more advanced LR techniques.
