Lenses / Roger Cicala: Canon v. Nikon lenses on optical bench (no camera)
« on: September 06, 2014, 09:30:40 PM »

Roger at Lens Rentals is comparing 24-70's and 70-200's from Canon and Nikon.  Interesting because it removes the huge variable of the different camera bodies you usually have.

I found this Nikon Rumors thread kind of interesting to snoop on.

Personally, if I had to pick one aspect about bad image quality at high ISO to address through sensor tech, I think it would be the low detail problem rather than the grain/noise problem.  It is not a slam-dunk choice, but I think the available software does a halfway decent job in smoothing out the noise artifacts, but not much good at all at supplying detail which was not captured by the camera if you intend to crop much.

In other words, it seems like a high MP sensor would solve more problems with its increased detail than it would cause with its tiny noisy pixels.

  Is this completely wrong?

Third Party Manufacturers / What's next, per Sigma Rumors site
« on: May 17, 2014, 10:17:44 AM »
This is an interesting site to check in on every once in a while.

Supposedly a 24mm and a supertelephoto coming next?

Animal Kingdom / Designing a bird shooting station?
« on: May 04, 2014, 09:12:18 PM »
Hi,

I am not enough into bird work to justify investing in a 500 or 600mm lens, but I like feeding them, and thereby luring them in close for easy shooting with my 70-200 lens.  My past setup was to hang feeders on the old awning frame over my deck, but the mess it made had become such that I am stopping that.

Now I want to set a post for bird feeder(s)s in the ground outside my picture window, mask off everything but a little hole to shoot thru, and let the mess happen in the grass. How does this sound:

A 4 x 4 post in the ground.  A cross arm of some kind from which to hang the feeder.  A thing like a flag holder or two mounted below so I can cut branches and have them stick out away from the feeder, so I can get shots of birds on a branch, not birds on a feeder. 

Has anyone done something similar?  I welcome input.

Thanks!

EOS Bodies / EF lenses could work on a mirrorless body, right?
« on: March 16, 2014, 03:29:13 PM »
I don't have this wrong, do I?  If they made a mirrorless body that wasn't super thin, but rather the same basic thickness as a DSLR, then there would be no problem?  The adaptor that lets the M camera use EF lenses is really just a spacer to get the lens farther from the sensor, right?

If so, given the huge line of EF lenses that the DSLR makers all have, couldn't they go mirrorless without needing to create all new M lenses, and making EF lenses obsolete?  I don't think most serious amateurs would really want cameras to get small.  A lot of folks say they like the bigger cameras because they are the right size for handling. .

Third Party Manufacturers / Sigma 50mm f/1.4 Art: Next week at CP+?
« on: February 04, 2014, 08:54:11 PM »
Will we see this next week?  I had just broken down and bought the Sigma 35 Art 2 for Christmas, barely a month before this development announcement.  I had wanted to wait for a Sigma 50 Art, but I like the 35 so well I honestly can't say I regret it at all.  If this new 50 does live up to some of the hype I may still be tempted.

Would a 50 and a 35 be too redundant?  Would I be better off waiting for the Sigma 135mm they also are supposedly working on?

Canon General / NYT: Only Canon, Nikon and Sony will survive?
« on: January 01, 2014, 07:58:06 PM »
Interesting article from December 20.  Says smartphone selfie-shooters are not embracing the mirrorless bodies in the way it was hoped they would take to a somewhat smaller setup.  Perhaps they will eventually leave off trying to make a "kinda smaller" camera that is too small for most serious shooting, but still too big for selfie-phone man, and keep making cameras that are the proper size for 2-handed shooting. 

Also says the Big 3 will endure but the also-rans like Panasonic, Pentax, Olympus, and even Fuji don't seem like good bets going forward.

Personally I hope Fuji at least makes it.  Original sensor tech and an elegant package.

I have recently purchased three Phottix Mitros+ flash units. I have been playing around with them, and a couple of light stands and shoot through umbrellas.

The manual says that the power cuts on the transmitter and on the receiver are "cumulative" to each other.  This definitely proves true in my experiments with them so far.

Does this mean that I am basically getting a lot more low-power settings using two units than you could get using just a single unit on camera which would bottom out at 1/128?  I Have noticed that sometimes 1/128th power is too much up close. So does using a wireless flash like this really extend the low-power capability of the flash in the way that the math seems to suggest?  If so, that is a serious extra benefit to having the two units and the wireless connection.

Hi,

What makes one monitor vs. another good for photo editing?  (If anything).   

I want to get a new one, and I want to get the right type. Not looking to spend more than $400 or so unless there is a good reason, and I really don't need anything bigger than about 23" or 24" or so.   I use Lightroom, but plan to get into Photoshop Elements sooner or later. 

Thanks.

Site Information / lens gallery could be easier to browse
« on: October 04, 2013, 11:46:26 PM »
Hi guys,

I like the lens gallery, but it is frustrating to look through it. Even if you sort the topics by title, the lenses are out of order because the titles are not standardized. It would be easier to find what you are looking for if the titles could be all rewritten in the same format so lenses would be in a predictable manufacturer and mm length order when sorted alphabetically.  I don't know if that would really do it though, because of the way zoom lens lengths contain 2 values.

Way better still would be to just have more columns with sort-by headers.  Currently you have subject, original poster, last activity.  it would be very useful to add:  Manufacturer.  Zoom or prime.  Focal length.  That would really make it nice and easy to use if you could click on one of these at the top of the column and have the list sort itself on that criterion.

Also, is the site capable of displaying more posts at once ( or all of them at once)?  That would keep you from having to flip through pages, and would instead make it a much more easily-scanned single list.

I really appreciate the site, and thanks for the work you guys do. 
Thanks.

Third Party Manufacturers / What accounts for bold Sigma improvements?
« on: September 23, 2013, 12:55:21 AM »
I believe their family founder recently passed. Is the new impressive vitality (QUALITY) coming from the new generation, or what?

Speedlites, Printers, Accessories / When will we see 430/440 RT flash?
« on: September 19, 2013, 12:55:10 PM »
The big 600 has been out a while now as an update to the 580.  When will the smaller flashes with wireless come out to update the 430?

Third Party Manufacturers / Sigma 50mm delay because IS (OS)?
« on: August 18, 2013, 01:39:50 AM »
It seems everyone on the face of Earth wants a 50mm that is as sweeeeeet as the Sigma 35mm. 

My prediction as to why they haven't yet released same is that Sigma wants to incorporate OS/IS into the lens.  Maybe that takes more time to perfect?  Any way you look at it, Sigma is KILLING it.
