Software & Accessories / Re: Microfibre Cloths for Lens Cleaning
« on: May 05, 2014, 04:59:44 AM »
One question that begs to be answered:
With so many "professionally" used cleaning aids, what would lens and lens filter manufacturers recommend?  And would they make cleaning kits for their products?  And what would they recommend as a technique to prevent wear and tear of the nanocoatings on the optical surfaces?
We could all use some of the manufacturers' insight, instead of trying an unproven method.

I've always used a rocket blower or microfiber cloth as my first choice, my breath plus microfiber cloth second choice.

Here's your answer lionrock....from the NY times article linked below...

"I spoke to Steve Heiner, the senior technical manager at Nikon, for advice on lens cleaning"...

" Start by blowing as much dust away as you can with air...the preferred product is a squeeze bulb"

"Friendly fibers. In most cases all you need is a good lens cloth. They are now made of microfiber, but get a good one"

"A perfectly good substitute for light cleaning is “a good huff of breath across the lens,” said Mr. Heiner"

Willow tit, taking a break from nest building.

Very nice series of a lovely bird, Eldar. It's always fun when people follow up on a bird.

Below is what I've been following for the past few days. As I have neither the skill nor the inclination for doing camo shots, I've been shooting from what I hope is a respectful distance of about 3 meters. This does mean I don't get to see the inside of the nest but it's the perspective we humans usually get anyway. I for one am just happy to see it at all.

Lenses / Re: 135L v 85 1.8
« on: May 03, 2014, 05:10:00 AM »
I've owned the 135L and 85 1.8, there isn't really a comparison between the two. I think the 85 1.8 is a great value but the 135 outperforms it in every way. Get it, you won't be sorry. But honestly if you're shooting weddings you might be better off selling your 70-200 and 85 and picking up the 70-200 f/2.8 IS II. I'd say the 70-200 II is just as sharp as the 135 and is a hell of a lot more versatile.

I've had the same experience.

And I agree, the 70-200 2.8ii would serve you well.

The 85 1.8 is just "ok" at 1.8 and 2.0 and because of that fact, I end up not using it because I would rather shoot with the 70-200 at 85 mm and 3200 ISO at 2.8 over the 85 1.8 at f2 and 1600 ISO.   The images are better even with the higher ISO.  (On 5d3 and 1dx, probably not on a crop body)

kaihp, I'm glad my post was at least a bit helpful, but I'm sorry to hear that you didn't get any keepers from the model parade.  Maybe you should just turn on the video for that portion :)

It looks like there's good light in the venue (not the norm) so that's helpful, but I'm still not sure about the results.  In terms of DOF, f/2.8 is why we buy the lens, but sometimes it's not needed. The reason I say that is because the photos you've posted all have rather clean and/or dark backgrounds.  In contrast, sometimes you NEED f/2.8 like in the photo below where the background was horrible and f/2 or better would have been nice :).  I would much rather have used f/8 to get the rider and horse in focus but I had to use f/2.8 to blur the background.  I chose to focus on her hand to compromise and got her face about 90% sharp and the horses face about 70% sharp.  My keeper rate was pretty low with this type of shot so I ended up shooting a lot of side shots where the rider and horse where in a much smaller focal plane.  I guess what I'm saying is that if you have the light, don't need to blur the background, and need to up the keeper rate, I'd consider f/4 or f/5.6.  If you're getting paid (and there need to get the shot) sometimes you have compromise your creativity a bit to ensure your photos are sharp.  On the other hand, if this is just personal work and you really want the shallow DOF, you'll just have to live with a lower keeper rate.


On your #11 note, I think that relates to what I was saying, f/2.8 isn't easy with moving objects and there's definitely some room between sharp, soft, and out of focus.  With post-processing tools, you can tweak soft areas to be sharper and if it's going on the web, even fairly soft photos can look sharp when down-sized.

Finally, here's the settings and situations that have worked best for me on the 5DIII:
Case 1: Just about everything except:
Case 2: For shooting birds, animals, and sports where trees, other people, and elements enter the frame while panning.
Case 4: For little birds like swallows that go everywhere at 100mph

Also, have you read the 1D X AF Guide (now in mobile version as well)?

As the two cameras are very similar, it's well worth a read.

Mack...you wrote "My keeper rate was pretty low with this type of shot"

Like you, my keeper rate with 1dx and 300 2.8 at 2.8 has always been fairly low with this type of shot. (subject coming straight towards me)

I almost always use AF case 1 with 4 surrounding points.

Does anybody have a high keeper rate with this type of shot when shooting at tele range like this and 2.8?  Or is it just something you learn to live with?

I got my confirmation....that I cancelled my order.

I just decided that I like my 24-70 2.8ii so much that I probably wouldn't use the sigma enough to justify the $1k.

Enjoy your new lens when it comes folks!   looking forward to seeing the images.

red tailed hawk looking for dinner near sunset....open field near a small lake.   the house in the background is some uber rich person's country estate.   one of those 10 to 15,000 sq. foot monsters on 25 plus acres.

i was driving around in a more rural area near lakes and open fields/farms

about 1 minute after this shot, as I drove away, the hawk flew straight at me and landed on prey about 50 meters away with talons stretched out.  i quickly stopped the car and fumbled to try to get a shot but all i got was blurry shots as he flew off with something small....damn.

hey jack..did i tell enough of the story on this shot?   ;) :)   ( i agree with you that more story/detail makes these posts more fun)

First time posting a pic. Just came back from wife's family farm. Oddest thing. We saw 5 osprey nests within site of each other, with each one having a pair mating simultaneously.

I have pictures of three of the pairs. The pic below is of a different fellow, a male who was working sentry on a different nest atop a silo....

nice shot tiggy! 

family farm...midwest I'm assuming?

the osprey must be making a very strong comeback in the US because i've been seeing loads of them this year. (in MN)   pretty cool.

i took this shot of an osprey yesterday near my kid's school....they built a nest on top of tall athletic field lights.
