Lenses / Re: Vintage Lenses: Any Advise?

I don't have any frist hand exp, but i would imagine some older F mounts might be a good idea. If that's not trick enough, you could get some Leica R mounts.

Lenses / another 24-70mmv2 review
« on: September 24, 2012, 09:47:03 AM »
http://www.ronmartblog.com/2012/09/comparison-canon-24-70-f28l-ii-vs-24.html

complete with comparisons to the 24-105. a lens i just bought, and now i'm wondering if that was such a great idea. well, i think i'm still good. with the money saved over the 24-70v2 i could still add the 35mm1.4 or 50mm1.2, or 24mm1.4, or...  so yeah, still okay i think. It's just i like to keep my amount of gear to a minimum. so I'd rather have one super lens than two very good lenses, but they all have different strengths, so what's a guy to do?

anyway, another review.

Just had to look it up myself. the position of the zoom/focus rings are swapped from the normal orientation, but they operate in the same direction.  it's the direction that would drive me nuts, i bet i can get over their positions being swapped. Reminds me how i swapped my gear shifting direction lever on my bike. 1 down 5 up, or 1 up 5 down. no big deal, but one time when i got in a bit too hot i did go the wrong way. i guess i was overloaded, but i worked it out. anyhow, continue the 24-70 doubting.... ;D

I'm not a video guy, but i've been taking little clips of my kids in the backyard, and at their sports, and they look pretty darn good. I must be missing something, as the 5d's video quality in these videos looks pretty bad.  When shown in this fashion every little thing is noticeable(as should be done) but that seems to be a bridge to far. I mean, that 5d footage REALLY sucks compared to the BM.

picked up a 24-105.

What? The 70-300L has a reversed focus/zoom direction? Really?

Lenses / Re: Drop in Filter for EF 500 or 600 f/4L IS II USM
« on: September 22, 2012, 09:06:58 PM »
I have the 300mm Is v1 and i had to search high and low for a long while to get my hands on the canon filter holder so i could use regular screw in style filters. I got it so i could use ND filters, real glass ND filters, and not fool with gels. I put gels on my flashes, not lenses(but i would if need be).  I hope you have an easier time than i did. really, i was searching B&H, Adorama, KEH, and others, some in the UK(i'm in the states), for this new or used.

personally, my biggest gripe with the Tamron is the reverse zooming/focusing, and what looks like a weird focus/zoom layout. but, i've had to dig deep to learn much of it. is the focus ring in the back? is it tiny? does it go the wrong(opposite canon) way?

if you guys ever bothered to read much of his stuff you'd learn that he usually recommends you not to buy the more expensive product. it's at the bottom of his reviews on things, under "recommendations". he'll usually tell you to either make do with what you have or go buy some much less expensive, usually older, model.

Roger is in a unique position of having many copies of so many lens. They all see a good bit of use, and he bench tests them all. I'm with you guys, his blog is very interesting and provides info that no other reviewer can obtain. The sort of info only Canon themselves would have in the past.

Lenses / Re: Which to get next: 35 f/1.4L or 16-35 f/2.8L...?
« on: September 20, 2012, 09:09:25 AM »
i would recommend the 16-35mm. the 35 is probably very nice, but you have that range well covered, so it'd basically just be what you have, 35mm, only faster. I really don't know why people talk about out of focus areas and 35mm at the same time. your 50mm, and 70-200mm are far better at throwing things out of focus than any 35mm. heck, you're 24-105 might do more as well. the 16-35mm will get you things you can't possibly get with your current gear. not just the same basic look with better IQ(the 35mm), but entirely different things.

actually though, if my main concern was trips, portraits and assisting weddings/events i probably wouldn't recommend anything given what you already have. you look good to me.

EOS Bodies / Re: 6D Sync speed only 1/180s?

Some of the early model DSLR's got there, and some of the Nikon's can do even better(the older ones).

Many of those were not FF.  With a FF sensor, the curtains have further to traverse.

Some of the early model DSLR's got there, and some of the Nikon's can do even better(the older ones). i have a leaf shutter 6x9 rangefinder that will go to 1/500th, it's from the 80's and probably mostly designed in the 70's. It doesn't even take batteries. why on earth are we not doing better now?

Leaf shutter ≠ focal plane shutter.

Not to sound like an ass, but I know all that, and i don't care. we can put a man on the moon, but we can't figure out how to get a faster synch speed? I take it you are some sort of doctor or at least a very well educated man. That is great and we are glad you hang here, but surely there is a way to get this done. I see  impossible things get done all the time.

bdunbar- HSS will get you the "correct" exposure at whatever f stop shutter speed you need, and it's very handy, but it has limits.  i shoot weddings and most of the time i'm standing outside in the sun trying to light a large group of people. say you get an exposure of iso 100 f5.6 at 1/800th. with a camera that has a synch speed of 1/200 i'd be 2 stops over that. when the HSS synch fires it doesn't fire one blast(let's ignore TTL preflash here) when the shutter is completely open, it fires over and over again, at a lower level, each time draining the batteries. After a large shot like that your batteries are strained, and the flash't range is limited more and more as you move past that 1/200th limit. you want to light a group with a larger light source than a direct flash? well, that eats light power. want them all lit with roughly the same amount of light, that means back the light up, and that eats power. that's just for fill. you want to overpower the sun a bit, as i usually do? now your in big trouble. you shutter has to be open for 1/200. the sun is beaming down for 1/200 onto your target. you can't go faster to limit the sun, so you stop down. maybe to f16. cool, now your unflash lit areas are looking nicey nice. Now you just bring up the flash to the level you like. I hope you have some power, as now you are shooting into an f16 sized hole for only 1/200. i use a 580,550,2x430's. most of the time i borrow my helpers 580 and i gang it with my 550/430's as a super "a"channel(gaffer's taped together, really!). when that doesn't work, and i expected it not to work, i haul out my big black box of sun, a speedotron 2400ws powerpack. but it's really a pain to use in the field and the thought of dying or killing someone with it's high voltage isn't nice.  if this all seems to be crap. go outside mid sunny day. shoot a target from 10-15ft away with your flash at full power(manual)and full synch speed. then see what you get with hss at 1/250-1/500. if your target is small and you are close(with your light) you will be fine. otherwise....  actually, i've been typing for so long i might even be starting to confuse myself, i hope this is of some use.

1/180 sucks and so does 1/200th. 1/250 should be the bare minimum but it really sucks also. I have a good understanding of the importance of all this, but a vague understanding as to why we don't have 1/500th or better synch speeds. Some of the early model DSLR's got there, and some of the Nikon's can do even better(the older ones). i have a leaf shutter 6x9 rangefinder that will go to 1/500th, it's from the 80's and probably mostly designed in the 70's. It doesn't even take batteries. why on earth are we not doing better now? YOu might say, yeah, but your rangefinder only goes as fast as 1/500, synch or not. well, i don't care. I don't want to hear it can't be done, do it. either with mechanics, electronics or both.  I say we officially end the MP race and heat up the synch speed race!

  BTW- this little rant wasn't brought on with the 6d, it's been building for a few years.
