RPT - ah, but you forget the 500mm is f4 and a 2x TC takes it to f8 so f5.6 would be tricky!

As many lenses are sharpest when stopped down a couple of stops, I thought f11 would be a good compromise (I understand that diffraction kicks in around here on the 5D3 but only if you look for it in shots taken beyond, say, f16 - cue the naysayers on that topic!). Clearly depth of field isn't an issue but maximising sharpness/detail was, hence the stopping down. The moon was very bright but you're still shooting through an awful lot of atmosphere which will soften the image. At ISO 320 I wouldn't really have any noise to worry about and with it tripod mounted, I manually focused in Liveview and set things to mirror lock-up, 10sec timer to allow most vibration to dampen down and IS mode 3, crossed my fingers and the rest is history.

Hope that clarifies things.

Ah! Clean forgot about the 2x. Thanks for the detailed description. Still waiting for the rains to abate. Yesterday I got caught in a downpour and was drenched through and through! The darn monsoon does not want to leave! Well, at least the atmosphere is getting a scrubbing :)

Hope to post moon shots when the clouds roll out.

Thanks Harry. I'll get it today. Looks interesting.

Nice work and not all that oversharpened...what radius did you use?  I assume this is a 100% crop?  How much better is the Kenko 2x TC, than the Canon series ii 2x TC?

Carl - Glad you (and rpt) liked the shot.

For info: f11 1/25th at iso 320
Adobe Camera RAW:
Sharp 66
Radius 1.6
Detail 61
Masking 0
(Basically mess around with the sliders 'til it looks okay(!) and also tweak the curves and contrast etc.)

The cropped image ended up 2512*1905 then was resized for posting here.

As for the Canon 2x mk2 TC. No idea! I've had the Kenko 1.4x and 2x DG 300 TCs for a while now. I originally got them for use with my 300mm f2.8 IS mk1. The 1.4x is very good, very sharp but the 2x is pretty soft so I only use it if absolutely necessary. I got the Canon 1.4x mk3 TC free when I bought the 500mm. I haven't compared the Kenko 1.4x to the Canon with regards to speed - I just assume (hope!) the Canon provides faster focussing as it's designed specifically for the mk2 big whites.

Both Kenko TCs aren't worth much secondhand so I'll probably keep them for use with my Tamron 90mm macro. Clearly Canon have a reason for designing their TCs the way they do but the protruding front element really screws up your choices of what lenses you can use with them.

Take care,

Guy, I have a question. Why did you opt for f11? Shouldn't you have shot it around f5.6? It is not like one needs any depth of field here. Also the light is not very strong so f5.6, 1/100 and ISO 160 would have been my preferred setting. Could you comment?

Thanks in advance.

Congrats on the blue ribbon!  Many talents.

I like the b&W.

I am curious, Adult Yeast?  Is there adolescent yeast?  What exactly does that mean for the non-bakers amongst us?

At local fairs, they have different age categories as well as different types of breads, so Adult stands for a entry from a Adult, and Yeast means that yeast was used to make the dough rise.
There is a Junior category for younger entrants, so it would be Junior Yeast.
This is also bread machine bread, and its a separate category, seeing that bread machine bread is often not quite as nice as hand made.  In my case, they lumped them all together due to the few entries.  I had just bought a new bread machine, and the local 4H leader was urging the parents of the 4H children to enter something, so it was a one shot deal.
I had just bought my 35mmL about 2 days before the fair, so I used it on my 5D MK II exclusively all day at the fair.  It wasn't always the best choice, but it did the job.
Ah! I was wondering if "adult" referred to the yeast or one had to show proof of age to be allowed to eat it ;)

It looks great! I am sure it tasted great. Congratulations!

It's fun to be a part of this thread with the varied and high quality shots that keep showing up from different folk.  I'm already starting to get panic attacks knowing that my bird count is about to nose dive.  There'll be nuthatches, chickadees, magpies and a few others like pine grosbeaks and Bohemian waxwings but nothing like summer!

Not to mention that the temperatures won't be kind.  :)

Why not migrate with the birdies ;)

If you plan to fly south (east) you are very welcome in Pune, India :)

I am waiting for The November thru March period when a number of birds get to near (within 100 km radius) where I live.

One technique for using a big lens with a monopod is to keep your left hand as far forward towards the open end of the lens hood as possible. Using your hands at both ends of the body/lens combo gives greater control over the heavy lens swiveling about its pivot point (i.e. the monopod). Doing this allows more control when panning and "fine tuning" the balance point. Keeping the left hand really close to the camera body will have the combo wanting to tilt all over the place thanks to that physics slut, Mrs Inertia.

For a pretty cheap but effective gimbal head try Lensmaster

I bought their RH-2 and got the shot below last night with my 5D3, 500mm mk2 and Kenko 2x TC. (Yes, I've probably over-sharpened it a bit too much but I leave the good stuff to NASA.)

Of course, you could just do weight training and handhold the 600!

Nice work and not all that oversharpened...what radius did you use?  I assume this is a 100% crop?  How much better is the Kenko 2x TC, than the Canon series ii 2x TC?

Looks great to me too. These monsoon clouds have obscured the moon since June! Hopefully in a couple of weeks they will mostly be gone... Will try with my 400L + 1.4x then.

If you want to handhold, which I do most of the time, you have to practice your standing position and the key is how you rest your elbow against your body. It is pretty similar to a standing shooting position with a rifle. If your elbow is not resting against your body, you will start shaking in seconds. You also need to practice your breathing. Again, pretty similar to what you do when you shoot with a rifle.

For tripod and monopod, I use Gitzo GT3542LS and GM5561T, with Really Right Stuff BH-55 and MH-02 heads. Since you were lucky enough to get the lens, you should treat yourself to something similar.

Have fun!
True! Photographers would make excellent snipers...

I like it a lot. The fact that there is so much black to the right makes you "fill in" missing pieces. I don't think it needs a border.

Yup! The sunsets I took from Newport Coast, I started up an hour before sunset until the light died out. The light changes so fast unless you have the camera (with the right lens on it) you are likely to miss it. You can try again tomorrow. Will it, ask for it and it shall be delivered to you :)

Darn! I almost sound like a preacher :P

Hi folks,

newbie here with more money than brains (or technique).  I recently was gifted with 600mm II and a 1.4x III (and a 2x III, almost forgot that one).

I did "OK" on a moon pic:
Nice one!

but I'm having trouble learning how to use this beast on other stuff.  I'm coming from a 400mm f4 DO + the 1.4x II.

I'll start by saying this 600mm out resolves the 400mm by quite a bit, even with the 1.4x on it.

That said, holding this sucker is a bitch even as "light" as it is for a 600mm (and it is light, you can hand hold it, just not for more than about a minute.  At least I can't).

Does everyone who owns a lens like this use a tripod?
I don't have the 600L but have you thought of a monopod? Much less hassle to carry around than a tripod.


On the tripod I got crap results unless I did live view (which locks up the shutter, still have to figure out how to do that w/o live view.  I did say newbie, bokay, don't yell at me.  Too much).

The moon pic is cropped, 5DIII + 600mm + 2x + tripod + live view + remote shutter release + IS on.  Is that just what you do when you have a lens this big?  I mean the live view remote shutter IS part.

I'm used to walking around and grabbing shots as they present themselves, the 400mm lets you do that, the 600mm is not so much.  I did get some keepers just walking around but a much much lower rate than the 400mm.

I guess what I'm asking is what is the basics of using a 600mm and 600mm+1.4x.  What settings do you use, do you always lock up the mirror, remote release, no IS or IS?

I'm new to this big bad boy and still not sure if it is for me, I love the sharpness and the reach, not yet comfortable with my sucky technique.
If the same image taken in live view is sharp and taken with AF is not, it means your AF needs AFMA done. I suggest you procure FoCal Get the Pro version.

Osprey leaving the water. Im keeping the fish shot for later.
Fantastic shor Mick! Look forward to the whole sequence.
