Software & Accessories / Re: Tripod centre column - yes or no
« on: July 01, 2014, 05:54:45 PM »
Raising the center column *up* adversely affects stability.  I think that is pretty self-evident.

But what about lowering the center column *down*?  Down as extending below and in-between the legs of the tripod?  Is that equally as unstable as raising it.  Is there any stability concerns with hanging the camera below the lowered center column?

I will often flip the center column when I am taking pictures of low flowers.  Is that a wise thing for me to do?

Wouldn't that lower the center of gravity of the entire apparatus... and much like hanging a sand bag on a hook on the column... it should have the same effect of adding stability.  I say go for it.

Canon General / Re: DOF and Sensor Size

I want to stay far away from this one... it just give me a headache. 

I know the answer is yes sensor size does affect DOF... and not just when you are framing the image similarly... and I know magnification has something to do with the whole DOF issue... but by george... that is about where my pretty smart brain take a rain check.

Generally I shoot sports.  I like the movie Big Year, but I don't really care much about birds. 

The 70-200 has been leaving me wanting lately... which is the reason for the gas.

And I pulled back on the throttle for the 400mm f2.8L... I looked at that price tag again and it was like cold water in the face...

JD...I have the 300 2.8 is and like you,  mainly shoot sports.....the addition of this lens is huge for field sports and night games.   It's my money maker.

Look what I see..... ;D ::)

While I have ya'll ear... is there an appreciable difference between the original and mkii version of the 300mm f/2.8?

+1

The money I started saving when I quit playing golf has quickly been eaten up by my GAS

I liked golf... but I wan't good at it.  On my best day I would be a bogey golfer... and on my worst day I didn't leave the bar between the 9th and 10th hole.  So... this is better.

Pricewatch Deals / Re: Canon EF 1200mm f/5.6L USM For Sale
« on: July 01, 2014, 05:23:46 PM »
I've never heard of the 1200mm... but it sounds really cool.  I'd almost lean toward getting a 600mm and putting a 2x tc on it... sure it would be f8... but you would want to stop down to avoid any vingetting anyway. :)

Have you handled a larger great white?  I'd suggest that you do and decide if you want a hand holdable or not.

The 400 is ii us m and 600 ii is usm  are for me marginally hand hold able (and thus less good for difficult birds in flight).  I have no experience with the 200-400.

The 300is ii usm and to a lesser degree the 500 ii usm are hand holdable and the 300 for sure takes extenders really well.  The MTF would indicate that the 500 does so very well as well.

So Id go for the 300 or the 500 unless you are in very good shape in which case any of the great white sharks would work for you.  If I were to buy a 500 I'd consider camera canada as they have a deal on the 500....

Sometime soon I'm going to the b&h super store in nyc, so I'll see how they feel.

Ok... while I'm walking down this road... 400mm or 300mm f2.8L?  I have the 70-200 f2.8L is mkii at present.  I would need to upgrade my 1.4x mkii to the mkiii and get a 2x mkiii. 

That would give me the following:

70-200mm. @f2.8.
400mm @ f2.8
90-280mm @ f4
560mm @ f4
140-400mm @ f5.6
800mm @ f5.6

Mmmm... that sounds delicious.

I'm the wrong person to ask because I don't care about my tripods, which I have about $100 invested in... but I would say that both of mine have a center column and when I use the column, it is generally due to laziness... adjust one or adjust all three, and for half extensions, having to check that all are at a suitable height... well as I said laziness.

I must be going a little nuts... I'm looking at 200-400's, 300/400 f/2.8's... and I'm seeing the price tag... and I thinking... "That's not bad." 

I remember fondly when I spend $100 on a 50mm f/1.8 and I thought that was a lot of money... I'm off to bed... this bug will surely pass before I wake.

honestly i was seriously looking at the 200-400 but could not justify the price then i decided the tamron 150-600 was so cheap it was worth a shot for my limited usage its gold while it definitely cant hold a candle to the 200-400 its still impressive and worth a look if you are in a similar situation

Thanks.  When I played golf I didn't want my gear to be the reason I didn't break par... So I bought good gear, let's say comparable to a 7d, and then my only excise for not breaking par was on me.  I have a similar attitude with my photo gear... So I'm not sure I can go downthat route... but I'm pretty sure I can hold off on getting a great white until it is warranted.

I know the feeling, but unless you will be getting a commercial/financial return from the investment, it does not make sense.

I did net fifteen bucks the other day from selling a print... So yeah... buy it now.

357
Judging from who is answering here, you are sunk.

My prediction, along with sugar plumb fairies dancing in your head, you will be dreaming of clicking "check out now" on B & H tomorrow morning.

I'm thinking 1DX personally, however that's me.  Tell us which one you buy.

I've bought the. 200-400 before, just to see how it felt.... but I didn't give a valid form of payment.  So I got a taste of the shipping experience, but neither the reward or the dirty looks from the wife.


358
Once your mind start thinking about the BIG WHITE, you pretty much bought it - THE END ;)

1D body becomes a piece of cake after ;D

I buy and sell gear to support my gas... kinda like a heroine junkie selling pot to find the addiction. And so I have to earn the money I use to buy new stuff... So it puts me at an acceptable pace... but I did the math and I'll be in reach... not quite there, but in reach. 

I do my best not to lose money on a lens purchase, that way I can essentially rent it for free when I decide to sell it... but I don't think that is a real option with the greats...

Yepp, the samyang 14mm lens is a hell of a lens for the price. Sharp and nice build. Just the barreldistortion is really strong. So don't try to make architectural pictures with it, at least no on film ;)

I guess I could try and fix it in post... but I just bought a 17-40 today for a song... I may wind up reselling it... but certainly if I keep it, the difference between 14 and 17 may be significant, but not to me.

You bought it for a song because the 16-35/f4L IS has pretty much made it obsolete - especially for FF. It is now quite clearly a second rate lens when compared with its newer cousin.

I'm aware, but I'm not a wide angle guy... and if you can find me a 16-35 f4L for five hundy, I'll jump all over that.
