Lenses / Re: Canon MP-E 65 f/2.8
« on: Today at 11:37:40 AM »
The lens does not focus at infinity and the working distance is tight, so you'll definitely need flash a lot of the time (effective aperture drops with higher magnification).  It is not a general purpose lens, it is a specialist lens, but it does what it does very well.  It starts at where the 100L ends, 1:1 and goes to 5:1.  DOF will get extremely thin at higher magnifications, so you'll probably start focus stacking a lot more.  The 100L is much easier to use for subjects that you want closer to 1:1.  The MP-E comes into its own for smaller targets.

At the pixel level, it is not the "sharpest" lens and it gets softer at higher magnifications, but it is sharp enough.  You can use it handheld and rocking back and forth to get the images for blending, but it's much easier to use on a tripod with rails.

Mac, I generally agree with your viewpoint, but I do wonder how Canon would slot this lens. Since the 24-105 "L" already sells for around $600 in white box form, it seems like it would be hard to make this lens competitive in price, unless it is really, really cheap.

Maybe they are looking to stop selling the 24-105 "L" as a kit lens, wait for the supply to dry up in the market and then in a few years introduce a 24-105 "L" II at a significantly increased price? If that happens, we'll all be patting ourselves on the back for getting the 24-105 "L" when it was cheap.

+1.  I'm guessing the 24-70 f/4 IS will replace the 24-105 f/4 as the de facto kit lens.  The 24-105 f/4 II would then sit between the 24-70 f/4 IS and 24-70 f/2.8 II.

I figure that the 24-105 is targeted to be sold it kits primarily.  Think of a 1000-1500 FF kit with a this 24-105 consumer zoom.

An EF-S 24mm f/2.8 pancake makes a lot more sense than an EF version given the size of the existing 24mm EF lenses, plus it gives the APS-C users the same FOV as a 40mm pancake for FF.  Canon could have make a EF 24 f/4 pancake, but that's a bit slow on FF and even worse for APS-C.

I'm not surprised that Canon is bringing out a new consumer line of lenses -- a line that falls below the L's and the midrange EFs (24 f/2.8 IS, 28 f/2.8 IS, 35 f/2 IS).  The camera market is not growing like it has been for the last 15 years, and FF camera prices are falling.  With falling FF prices, we'll start to see the reintroduction of consumer lenses for FF cameras.  Do people expect consumers to pony up $1000 to buy a FF camera and then $1000s more for lenses?  These lenses, which were ubiquitous with film cameras, did not sell well with their lower IQ and expensive FF bodies, but most consumers will be satifsfied with 24-105 or a 28-300 (rumored), and they might supplement it with another lens or two.

Lenses / Re: Best PRIME lenses to take to NYC?
« on: August 28, 2014, 08:24:50 PM »
If you restrict yourself to primes, then 35, 50, 85 and 135.  But why???  You lose so much focal length flexibility and range.

If it were me, I'd choose the 35, 50, 16-35 and 24-70, with the primes being used indoors or when you want shallower DOF.  If you plan on going on tours (bus or boat), then I'd take swap out a prime for the 70-200.

Lenses / Re: Which lens to take on bike trip?
« on: August 27, 2014, 11:45:59 AM »
70-200 f/4.  Length is more useful on that type of trip.  There might be some you miss, but you'll just have to adjust what and how you shoot.

Could you further elaborate as to the various types of filters offered by B+W?  The XS-Pro vs the F-Pro.. etc.  I don't see on the Schneider Optics page a comparison of the details of each.  What's the difference?  I found a thread online that claimed the F-Pro was made of brass whereas the XS-Pro wasn't, but according to Amazon, B&H, et. al. the XS-Pro is indeed made of brass.

I ask because between this thread, and this thread, I've gotten recommendations to go down the B+W route for filters.

Any help will be appreciated.  I'm going to post a similar question on the other thread too since I've inadvertently scattered questions across 2 threads.  I didn't realize that they were going to converge like this.

XS-Pro is a higher line of B+W filters.  See link for the features of XS-Pro, but in summary, XS-Pros are thinner (easier to use on UWA lenses without vignetting but not as many threads for the lens cap, which never bothered me), have multi-layered coatings and are easier to clean (nanocrystal coat).

Lenses / Re: Would you buy the 35L now, or wait?
« on: August 25, 2014, 04:04:03 PM »
If you want a 35 mm lens and wonder if there will soon be a better one available, get a used 35L and you can more or less get your money back any day if you want something else instead. The Sigma is also worth considering if slight AF issues don't bother you that much. Personally I would now get a used 35L if didn't already have the Sigma.

+1 on a getting a used/refurbished 35L.

No problem for me.  Did you check the lens on another body or do AFMA?

EOS Bodies / Re: Are These The EOS 7D Mark II Specifications?
« on: August 25, 2014, 01:55:47 PM »
Firstly, let me say that I do not have an engineering background or understanding that half of you folks do but I'm a little amused at the amount of damnation for a camera that nobody has even seen yet.

I know exactly what I want in the 7Dii but I guess it'll be different to every other Canon user's personal want list and as Canon are not in the business of Build-Ur-Own-Camera, they will release the best camera possible to us that they can.

On the DR issue; sure, I'd love Canon to have the upper hand over Nikon but right now they just don't. I've been in this position before though, I was a Sega fan during their 16bit war with Nintendo. 64 colours vs 256, mode 7. Street Fighter II was better on the SNES and yet, I still played games rabidly, day in, day out and loved every minute of it.

So once again, I'm not an engineer, heck, I'm only a very average photographer but I will use every moment I can to take photos because I friggin' love it!

It does seem to happen a lot.  Remember all the people poo-pooing the 6D when its specs were released?  Many of those here advocated for the 5DII over the 6D, but you don't see many of those in favor of the 5DII anymore.  If Canon did its homework, the 7DII should sell well.

Lenses / Re: A New Pancake Lens? [CR1]
« on: August 24, 2014, 09:59:42 PM »
Why would it be f/2.8?  The 24 f/2.8 IS isn't large, but it's not a pancake either.  A 24mm pancake that is f/4 would make more sense, but I'm not sure how useful it'd be a crop camera.

24mm & 28mm f2.8 IS is very good small prime, but the price is around 4 times to 40mm pancake.
Which is why I don't think it'll be f/2.8 or be as good as the 24 and 28 f/2.8 IS primes if it's priced anywhere near the 40mm pancake.  And why launch it with the 7DII, unless it is an EF-S lens, but does that make sense when Canon has not shown much inclinination for EF-S primes?

Lenses / Re: Canon EF24-105mm f4 IS USM time for a refresh?
« on: August 22, 2014, 02:41:46 PM »
Or... the 24-70 f/4 IS is designed to replace the 24-105 f/4 IS as the sole kit lens.  The 24-105 f/4 IS could then be redesigned to have better performance but for a higher price tag that will not be discounted as heavily because it will no longer be a kit lens.  Some will upgrade from the 24-70 f/4 IS to the 24-105 f/4 IS II because it will be better with a longer focal length.

I don't see Canon selling a kit lens that is 35mm shorter than Sigma's alternative, which will be cheaper than the 24-105mm mk2, and 50mm shorter than Nikon's kit lens.

If Canon were to offer an updated 24-105 f/4 IS II in a kit configuration, then there will little point for having the 24-70 f/4 IS in the first place.  And if Canon designed the 24-70 f/4 IS to be a kit lens from the start, so that it's production costs are reasonable, then it can discount it in a kit aggressively while maintaining a reason for people to look for a reason to replace their kit lens.

That will create the image of Canon downgrading it's kit to make buyers draw the short straw.

Perhaps, but if it can offer the kit lens at lower price, then it gets people to buy into the Canon eco-system, which is what matters.  The Sigma can't be included in a kit, so you'll always be paying full price for it.  As long as the 24-105 is a kit lens, Canon will not be able to raise the price to make developing a more costly version II worth it.  I am cynical, after all...   ::)

The 24-105mm is different from other lenses:

1. The 24-105mm is a kit lens for two FF cameras, so it's white box price is a high priority for Canon. Therefore, Canon will be more sensitive to it's production costs, and less willing to invest in making the big investment in replacing it.

[This plays part in both upgrades from crop and in competition to Nikon kits.]

2. Being a kit lens, it should be positioned so as to encourage photographers to upgrade to other lenses - better, wider, longer, faster, etc.

A new 24-105mm would be detrimental to both causes, so I expect Canon to delay upgrade as long as it can.  Currently Canon has the advantage of being able to offer a more attractive price in a kit, so I don't see how an upgrade would be urgent from Canon's point of view.

Third Party Manufacturers / Re: Dustin Abbott Reviews Tamron 28-300 FF
« on: August 14, 2014, 12:16:27 PM »
I'm not crazy about f/6.3, either, but it is also 1/3rd of a stop of light.  It is rare that the 1/3rd stop makes much of a difference, and the high ISO performance of the 6D that I use it with means that I can get away with cranking ISO and still get very nice images.

I suspect that the 28-300L probably has higher resolution than this lens...but I doubt the difference is significant.  This lens is surprisingly competent (I wasn't nearly as impressed with the new 16-300 VC for crop).

Does f/6.3 affect AF performance when using off-center AF points?
