Canon General / Re: Lose or Loose?

Ever since English has been spoken and written people have been complaining about its misuse.
I used to be one of those people but I yield to the understanding that it WILL change whether I like it or not.

Just think how much it has changed since Lincoln wrote the Gettysburg Address. The people of that day would be both amazed and despairing of how the language had changed. Not to mention being astonished that we wasted time taking pictures of our food and our cats.

EOS Bodies - For Stills / Re: High Megapixel DLSR a niche market?
« on: October 26, 2013, 11:09:09 AM »

It's niche in term of how many cameras Canon will sell, and how much profit Canon will make from it.

Absolutely correct. Canon has a huge line that has a ton of sales volume.
Canon got sidetracked in the MP race a while ago precisely because the were responding to their customer demands for better video and low light performance. Nikon continued chasing the MP numbers because they did not sense a cost -effective battle in the video arena.

The manufacturers only chase so many rabbits.

Canon General / Re: Benefits of a mirrorless FF?

As far as I understand, it's the other way around - the farther the pixels from the optical axis & the shorter the flange distance, the obtuser the angle the light hits the pixel, causing vignetting. As far as I gather, this is already an issue on current FF cameras with fast and/or wide lenses, e.g. the 24mm f/1.4 L II has >3 stops of vignetting when wide open (translation: corner pixels record ~1/10th the amount of light center pixels record).

True.  Also, the wider the aperture, the more issues there are with the oblique light angles not being collected by the microlenses, and that issue worsens as the pixel pitch gets smaller.  Current cameras lose up to a full stop of light int he f/1.2-f/1.4 range, and some cameras clandestinely boost the ISO of fast primes by up to half a stop to compensate.

I will add that this is precisely the argument Olympus used in the development of the 4/3 system. They argued that by creating a lens system tailored to the unique properties of a sensor that IQ could be maximized. Thus the 4/3 lenses were not too much smaller that we may have been led to believe.
I also suspect that a number of FE lenses may be old formulas in new barrels to save time and money in getting lenses to market.

Thanks for posting this.
I will look into this ASAP as I have noticed a few odd quirks in my flash exposures but have been too busy with the event to track it down.

Third Party Manufacturers / Re: Sony A7 or A7R pre-order list

short register distance with class-leading FF sensor = nice compact back for whatever you want to put in front of it.  Smart thinking Sony!
This could be the sort of modular imaging tool that appeals to gear/tech geeks in a big way.  And the price point is practical enough.
I'm mildly excited by this product, it's really cool!  And useful for more than typical photo-video applications... microscopy for example.. astrophotography?

No pre-order for me, but I'll definitely keep it in mind for some goofy project to justify getting one.

How about a Rhino-cam?

Distortion may drive you crazy but I have no problems with it as LR corrects for it automatically.

I use the 100 macro in the studio along with the 85 1.8. Both are razor sharp for portrait /fashion.
I also use the 70-200 2.8L v1 and it is also super sharp.

The zoom has tremendous versatility (and weight) and has only a slight disadvantage in ultimate sharpness compared to the primes. The contrast is lower especially wide open. but a little bump in post solves the problem.

The most cost-effective mix IMO would be the 70-200 2.9LII and a Sigma 50.
This would not overlap FL. If you need the macro get the 100L as it also works well as a portrait lens.

The 135 f2 is supposed to be legendarily sharp but if you are not using it wide open all the time you are carrying a lot of weight and expense without any real benefit.

You say you want to get MF setup? If you are having trouble affording the Canon lenses you are going to be in tears trying to buy MF gear unless it is used film equipment and then you will be in tears finding processing and scanning to fit your budget and meet your quality demands.

(and the ones that are lured away may find it isn't necessarily going to meet all their needs).

As others have stated, the lens selection is terrible. For those who are excited about adapters to mount EF lenses while retaining AF, all other current examples of this are almost completely worthless if AF speed is of concern to the type of work you do.

The appeal for me is a quasi-open system that allows me to choose what sensor to attach to what lens. IOW, I would be very happy to attach my Canon 17 TS-E onto a 36MP FF camera AND also be able to use the Nikkor 14-24 f2.8. My style of photography is tripod mounted, Live View focus images. AF would be nice with the Nikkor but as I am never shooting action or BIF it is not an issue for me.
For events where snappy AF and cool lenses are required I would choose the Olympus as the lenses and the larger DOF would get me more keepers. The AF is fast enough to keep up with wedding action so, for me, that would be ideal.

As noted, depending on the style of photography one would make different choices.

I am also confident that Sony will offer a better lineup of lenses but I am also confident that people will whine about the price.

Third Party Manufacturers / Re: Sigma 24-105 f/4 DG OS Outed?
« on: October 14, 2013, 11:26:44 AM »
While I am interested in any new lenses that promise quality and novelty I am surprised at how many people are disparaging the Canon 24-105L.
Enormous numbers of copies are out there and still command high-ish prices used and new ones sell steadily it hardly seems that it is a pig.
My own copy is very sharp with admitted weakness in soft edges and distortion but I am able to overcome the distortion in LR and the sharpness in the corners is acceptable when stopped down to f11 in those images that need it.

My biggest concern with the Sigma is that even with the great and admirable improvements they have made in IQ and build quality, their AF performance leaves a lot to be desired. Various review sites have noted the sometimes iffy AF performance and my own experience mirrors that.
If I knew that the AF would be on par with any of my Canon lenses I would be on it in a flash.

Some time ago, I've been told by an alleged pro photog that real photogs don't crop, or at least only do minor angle correction. I am wondering if this is true, or it is an old-school fairy tale from the analog age that falls into the category "real photogs don't use auto iso and only shoot in full m".

While I have heard the same thing (or variations such as "Use the whole neg, you paid for it") I see no use in being a slave to an arbitrary shape such as 4x5, 6x6 or 35mm. The fact is that an image is your creation and you can do as you see fit. It is not some sort of whack contest to see what you can stuff in a frame.

Although guilty myself, I no longer am enamored of the "cutout neg carrier"or "sloppy borders" trope that used to attest to ones FF integrity. One can easily drop a black border around any shape if it appeals to you but the notion that one must go "mano a mano" with your format is foolish.

Well, they can price it any way they want. I am sure they will sell enough to make it worth their while.

What amuses me is that it will leave those complaining about Canon prices a little breathless.

Its a vegan lens. Slightly more money but worth it.  ;)

Have to agree with Neuro.
The current prices of the Canon and its real excellence will be a hard act to follow.

My copy needs a CLA buts is still a go-to lens for 80% of my shooting. What I really need is another for backup.
It is a decent lens, but not really an "excellent" one. It could use way more sharpness across the frame, especially in the corners. I wouldn't use the 24-105L for landscapes.

Sharpness is probably one of the things that Sigma is going to bring to the table.. And lots of it.
In my experience the 24-105 is plenty sharp. I rented the 24-70 2.8 L II and found it only a touch sharper than my lens.
For real world work I have found it to be a great step up from the old 28-75 Tamron that was touted as the top "value" lens at the time ~4-5yrs ago.
The real world for me is working with the vagaries of hand held shooting, motion and the use to which the final image is destined. Even the most demanding applications (large prints) are well served by this lens.

Studio shooting with side by side comparison to my Canon 100 macro (on camera stand) show the macro to have the edge in absolute sharpness and better contrast but no client will ever see the difference.

Third Party Manufacturers / Re: DIY filterholder
« on: September 07, 2013, 01:22:42 PM »
Ben Egbert and I discussed doing a DIY filterholder utilizing the 17's front cap in April 2011. I am not handy so I had to wait until Ben actually did the work and produced a tutorial. (See below). Total cost for parts = $80 or so. You will not ba able to buy the Lee version (if real) for 4x this number. In the meantime, a bunch of folks popped on the internet with the same or similiar idea. Except for some vignetting in areas of the frame that appear when the shift is too strong, works like a charm.

Followed his work on another forum and he later said (I think?) that the thing fell of due to the glue not sticking hard enough. He also mentioned that he would not make another one since the front-cap with the standard-holder was better alternative. Smaller and less vinjeting.
If I'm not all wrong.

I saw all the DIY solutions and long ago learned the cost of the materials is nearly irrelevant to the labor and PITA of cutting, gluing and praying it works.

For me the Wonderpana is a very well built solution that really works. Infinitely better than any DIY solution.

BTW @Privatebydesign, I am pleased my 100th post was a helpful one.

Having looked at the WonderPana 145 Essentials Kit I am interested in getting one for the polarizer. Could somebody who owns one post a picture of it mounted on the 17TS-E please? Whilst I can understand how it works on the 14mm and the Nikon 14-24 I don't see how it fits the 17TS-E without mounting on the focus ring. It would be a great help if I could see one before ordering, thanks.

Here you go. As you can see it is mounted via the bayonet of the lens cap. Very secure and does not vignette with movement.
Added Bonus is some protection of the front element.
