Third Party Manufacturers / Re: Patent: Tamron 150-600 f/5-6.3

A fixed focal length of 600mm and (preferably) f/5.6 would be a much better choice and it would be a little easier I guess to achieve good optical quality. YMMV.

For me, it would have to be lower than the cost of the 70-200/2.8L IS II, which is a bigger lens, with bigger elements, spectacular optics, and IS.  To get there, they'd likely have to reduce the cost of the II non IS.

Just noticed now... Why is it your focus is better and a lot sharper when the model doesn't wear anything except paint? :D
The zoom lens got excited  ;D

« on: October 29, 2012, 09:37:07 AM »
We'll know this for sure within a few days (hours?) but I thought I would take a stab at what lenses they'll announce.

Most likely
35mm 1.4 II - priced somewhere between $1700-$2100
200-400/1.4x - priced at $10k

Possibilities
TS-E 90 II - magnification near .5x, similar updates to other TS lenses, priced at $2100
TS-E 45 II - similar updates to other TS lenses, priced at $2100
400/5.6 II - much sharper.  Has new gen IS.  Priced at $2300.
300/4 II - much sharper, takes extenders better. Has new gen IS.  Priced at $2300

Unlikely
100-400 II - no more push/pull, much sharper and faster.  Priced at $3000.
135/2 II - Priced at $1900.
MP-E 65 II - Significantly better optics, maybe increased magnification.  Priced at $2300.

Not happening
14-24 - Maybe an "in development" announcement, which means 2014

Ok, so it's 10/28 and Photoplus is over.  What new lenses were announced?   :o

And where is the new 46mp camera and the 7D II

Well all these seemed more like a wish list anyway and nothing more...

Do you have complains from all 3 lenses you mentioned? If I were to guess I would say that the 70-300 DO is the worst of the three.  The other 2 lenses have a reputation of being very good (I used to have 10-22 until it was stolen). Do you use them at optimum apertures?

Pricewatch Deals / Re: The 5D Mark II & 5D Mark III Get Cheaper
« on: October 29, 2012, 07:49:26 AM »
So, buying cameras as an investment... how is that working out for all of those that bought the 5D3 already?
Well that depends.

 I bought a 5D3 (but paid in Europe 2700 instead of the usual 3000-3500). It wasn't exactly an investment. I bought it to have a second body (OK my 5D2 became my second body...). Prices in Europe do not drop so fast  :( so waiting a lot does not have so many advantages.

Now, If someone is a pro who has used 5D3 a lot these months then it was worth the money.

Number 2 first, I found one I believe in here:  http://www.adobe.com/products/photoshop/extend.displayTab2.html#resources  In the profile downloader area.  There was just one for the lens.  In the profile list I think it was listed as canon and not samyang/rokinon/etc.  Works great to remove the crazy distortion.   There so much resolution everything is still highly sharp after the correction. 

I haven't tried the Milky Way yet as the real good parts aren't high up now.  I wonder how well it will work as there is a lot of vignetting and light loss at F2.8.  May not matter given the brighter parts of the Milky Way get put in the middle.  It just has a way of not feeling like F2.8 I guess. 

Edge to edge is pretty sharp at F2.8 infinity.  It doesn't seem you even gain much more sharpness by stopping down than from where it starts at.  But I haven't used this lens all that much yet.  And my new/used 5D II also has a flange to sensor plane difference that needs fixed, but even on that it's good to go.

Can you please get a picture of the night sky with the lens fully open and see how the stars show at the corners? If the lens has coma (which even Canon L lenses have fully open) they will look like ... seagulls!

well i just may have to save up a little bit longer then for this since the general figures seem to point towards Lee system.. also something else i would like to clear up is i do plan to move to full frame eventually so it is something i would want to be compatible (doesn't vignette really) whenever that maybe.. the holders are slightly confusing to me.. so can you basically buy a holder then as many adapter rings as you want to fit different size filter threads of your various lenses? or are certain holders only compatible with certain rings?

Check this:  http://www.leefilters.com/index.php/camera/system

Generally you will get the filter holder and adapter rings. You need at least the 77mm wide angle version (there  are 2 versions standard and wide-angle, make sure you get the latter).

The filters will be 4X6 inches (10X15cm). There are 1,2,3 stop ND filters soft or hard.

EOS Bodies / Re: Canon to start using 0.18um (180nm) process for FF?
« on: October 28, 2012, 09:11:49 PM »
I don't expect the 7DII to have the same relationship to the 5DIII as the 7D did to the 5DII - a lot of people who could not afford a 1DIV bought a 5DII and 7D.
Now, if -and that's a big IF- 7DII uses the new technology sensors and an AF system that is between the 7D's and 5D3's (hopefully 5D3's) then I cannot think why it couldn't be the new wildlife camera. An 18Mpixel APS-C sensor with a quality close to 5D3's would kill... Of course this would cannibalize the 1DX and the new super telephotos sales

Some more clarifications. With Cokin P the 16-35 may vignette. I use the Lee filter holder for 4x6 inch filters.
The equivalent in Cokin is not the P but the  Z-Pro holder.

I remember though that not all ND graduate filters are pure gray.

I have the Lee set so I was able to comment on it. I do not have the Cokin P set with graduate filters so as to make a comparison.

I just saw your budget. I am afraid that my recommendation will cost more...

Check the Lee Filter System. Judging by your signature in addition to the filter holder you will need a 77mm filter thread adapter too (both 70-200 2.8 IS II and 16-35 version 1 have a 77mm filter thread)
Just make sure you select the Wide-angle 77mm adaptor.

As to the specific filters I would suggest that you get both a 2-stop soft ND and a 3-stop ND filters.

$2k for a 135/1.8L IS would be fine by me. The 135/1.8 of Sony is $1,800.
Which means Canon with IS would cost around $2.5K not $2K
Now now dont be too hasty. Sony has been historically more expensive than Canikon due to economies of scale.

IS and Series II tend to be double that of non-IS and Series I.
That depends whether the two features will be introduced at the same time or not. IF Canon either gives us IS or 1.8 the price will increase very much and (unfortunately) it will increase again when they will introduce the second feature. If they introduce both features at the same time maybe $2K is possible.
