Third Party Manufacturers / Re: Opinions on Sigma 85/1.4?
« on: Today at 11:37:14 AM »
Never used the sigma, but what will be your main subjects or type of shooting you aiming for?

There are a few alternatives to the Sigma if you can live with manual focus (with AF confirm thru adapter in some cases)

The Nikon AF85mm f1.4D is a good alternative, with some compromises....
Then you have the Canon TS-e-90mm, Rokinon 85mm ...and ofcourse the Otus 85mm

Lenses / Re: Inconsistent reviewing of lenses
« on: January 21, 2015, 03:12:19 PM »
Ok, I do think we need a policy that requires reviewers to be certified and licensed in the state or province where they reside.  Furthermore, such a license should not be issued to anybody who does not have at least an MA and an inspected, state-of-the-art lab.

Facetiousness aside, we get what we pay for in reviews.

And worse, paid influencers are all over the place, even on this website, alas.

To quote Mr. Monk, "It's a jungle out there."

Thankfully, AlanF and others are sharp enough and concerned enough to spot and report poorly executed tests and reviews.

Haven't you heard? if it is on the web, it's true....  :P  ;D

It's good to hear about other people experiences and feedback, but as mt Spokane is saying not everyone is qualifyed to perform reliable tests - there are only a few

Reviews / Re: Review of the Zeiss Makro-Planar T* 2/50 ZE
« on: January 20, 2015, 12:14:38 PM »
WOW - I have to say it Dustin, you really disappointed me with this review.

Do you realize the that the throw from infinity to 1 foot is just a smidge over 3/4inches?
Aren't you aware that a common trait, welcomed and desired in macro lenses (even half size as this one) in indeed the heavier focus dampening and long throw below 1 foot range, as precision focusing really matters?
Also, it's very common to see the a very narrow DOF in macro lenses, as it's common to have an above average sharpness.
Further more, almost no macro shooting occurs with a lens wide open- nor even if doing photo stacking.

I am surprised and shocked after reading other reviews from you, seeing you bluntly fail and commit such amateur, uninformed mistakes thru your comments.

Can't compare this lens to a canon 1.8 nor even the Otus 55 - It's a whole different league, and built for a special purpose...but can be used everyday.

You are certainly entitled to be disappointed with my review (BTW, Zeiss certainly isn't: https://www.facebook.com/carlzeisslenses/posts/937419462934961; https://twitter.com/CarlZeissLenses/status/557213223095894016), but I'm not sure where some of your points of view are coming from.

If you have used the lens, then you should recognize that the focus throw is very long.  As I point out, that's great for accuracy, not so great for speed.

The reason for the heavier damping that I give is directly from the president of Zeiss of the Americas.  I don't personally like the weight compared to all other Zeiss lenses I have used.

Of course the DOF is very narrow at macro distances...that's the whole reason I supply that information.  "That aperture advantage over the typical f/2.8 of most macro lenses is great for use in a variety of applications, but macro is really not one of them. DOF is only .08″/1.98mm at minimum focus distance and maximum aperture. That is TINY! Even at f/5.6 the DOF is only slightly over half a centimeter at the minimum focus distance." - The point here is that you AREN'T going to be using the lens at f/2 for macro purposes.

I don't think your particular criticisms here are valid.

I own and use the lens quite often - one of my favorites, and I don't like the 50mm focal range, but this lens it's the only 50mm (not 55) I like to use.

With that said, check again the throw from 1 foot to infinity or even from a more usefull 3 feet. And then compared it what other 50mm with AF are doing, as how much turn they need to accomplish the same.

The dampening on that initial focal range is not bad IMO - indeed becomes a chore after that.
No, I won't use f/2 for macro, but portraits or details at a bit over 5 feet will work very well - in the macro environment, the f/2 allows you to start with a brigher viewfinder view - a bigger difference comparing to the ef 180mm macro from canon, but not so much with the usual 2.8 aperture from other dedicated lenses

In all, looking at a halfsize macro from a point of view used to judge a generic walk-around lens it's faulty to say the least

My criticism applies to your generic review pointers on a non-generic purpose  lens - I can see you coming around this "street" calling a canon EF 500mm as not great for walking around town and shoot candids

At last, a Canon lens that goes straight on to my 'need to get' list ;-)

Price looks just fine ...YMMV ;-)

taking quite some time to do it, but it's ok if they do it right

Lenses / Re: Rumored 11-24mm f/4 true or feint?
« on: January 12, 2015, 11:15:57 AM »
Been long waiting for "whatever"-24mm from canon like many others.
I sold the 17-40, never got to love the 16-35mk2 but indeed I have now the 16-35mm f/4 as a permanent fixture on my camera.
I have also the sigma 12-24mk2, and yes, not sharpest tool in the shed, and one has to be carefull with flare.-but it does the job that a 16 or even a 14mm prime can't do.

I would like to see a 11 or 12mm prime (retilinear) if indeed canon can't release a high quality UWA 11-24.
Better yet if indeed the lens design would allow a flat front element or would have some lens shade design allowing for an adapter.

How difficult would be to make an UWA with a drop-in filter like the big whites have?

Lenses / Re: Rokinon 14mm vs 24mm for night photography
« on: January 08, 2015, 04:23:25 PM »
Something to remember when you hear people talking about star trails forming after so many seconds at a focal length...you really may not want to trust them, since they likely don't know what they're talking about.  It really depends on where in the sky you are shooting.  You'll get more star trails shooting perpendicular to Polaris at 17mm than you will shooting directly towards or away from Polaris at 24mm.  Don't put a figure in your head, because you'll be disappointed when it turns out it's not necessarily true.  Even at 14mm, which is really wide, you can start to see the stars beginning to trail if you're shooting east or west at 30 seconds.

That being said, I believe the 14mm is amazing for night photography.  It's a sharp lens on it's own.  It's relatively fast.  I like the 14mm over 24mm focal length for night photography because I can include more stars in the scene while still having an interesting foreground.  You can, of course, do night photography at 24mm, and I've done it, but I personally just like to be able to include more of the sky than 24mm allows.  It really depends on how you shoot.  Besides night photography, the 14mm is stellar (roflmao, get it?) during the day too.  It's true that it's not easy to put a filter system on it, but I've found little use to do so.  There have been a few cases where I would have liked to use an ND filter, but in the end, I just whipped out my 16-35mm.  I've also, with some success, although a lot more post processing, placed my already existant 77mm ND filter in front of the 14mm in several different spots to cover the image, and gotten a series of images I can blend together which is in essence one shot from the 14mm.  This doesn't work with every scene, obviously, but it is one of those last-resort options that you should be aware of.

Hey SP,
please re-read the post again - "a bit more than simple math" .
Besides I am not passing gas - just some broad information; it's up to the OP to dig/search a bit more, and to trust in learned lessons rather than assumed teachers/KIA.
Not all nightscenes can/should/must be pointed at polaris, and many can be shot with FLs way above 24... in many cases only if a tracking gizmo is used
The new 16-40 does a somewhat better job with coma, but still not much better or good enough IMO

DROB: there are filter mounting kits for the Rokinon 14mm:

Not sure if the Lee FK can be attched on the Rokinon 14mm - maybe you should email them directly and ask, as you have the system already

« on: January 08, 2015, 10:23:55 AM »
a bit more than simple math, but just to give you an idea:
14mm @ 500 = 35 seconds of exposure before star trails showing up (uou could use 600 but might not work)
24mm @ 500 = 20 seconds

Obviously, you will have to account more light at 1.4 vs 2.8, and in neither case I would shot fully wide open.

Not sure if indeed the Rokinon 24mm is as good as the 24mm minimizing coma distortions

You have the 24-105mmm - use it @24 to get an idea of FOV

....and then you have the Tokina 11-16mm 2.8 (this time you do the google search)

Dear Friends and Dear Teachers.
I just talk to my Photographer friends at the Town Camera club, and One recommend me to get This Fastest Lens  CANON EF 50 mm F/ 1.0 L USM= $ 2500 to $3500.
Yes, I have a GAS. Illness again.
Yes, Quite cheap for this fastest Commercial Lens in the Market, But When I do my research last night, and find out that, not quite sharp and great as new Canon 50 MM , F/ 1.2 L

http://www.wlcastleman.com/equip/reviews/50mm/index.htm

Sir/ Madam, I am not the real Fan of 50 mm Lens, and I already have EF 24-70 MM F 2.8 L, 40 MM. Pan cake,  Canon 50 MM F/ 1.8, Sigma 50 MM F/ 1.4 ( Old model , not Art), Yes, And Super fast Canon EF 85 MM F/ 1.2 L MK II.
What do you think about this F = 1.0 L Lens ??, Sir/ Madam.
Have a great day.
Surapon

So, what's your budget?

Anyway, as Eldar is saying, you would be better off with  the Otus 55mm (there is one for sale at FM btw)

A while ago, I saw a blog showing how to fix the 1.0L - not for the faint-of-hearth; so it's possible to fix the focus issue, but involves dismantling , rewiring and resoldering....

Lenses / Re: Travel gear thoughts...
« on: October 21, 2014, 03:07:50 PM »
I am going on vacation soon - which will consist of 2 one-week of backpacking trips plus some day tours, and pretty much struggling with same issue.
It's vacation but want to take pictures, and I know the locations are stuning. However, I will be carrying over 35 pounds of gear and food, so anything above a P&S is really a luxury...and additional back pain  :'(

I decided to carry my G1XmkII covering the 24-105 range for everyday/time use and bring the 5DmkII with the 16-40mm f4 for the landscapes shots. Been debating with getting the 70-300mmL or carry a WWA prime along with another fast prime (maybe macro) instead of the 16-35. I considered the sigma 12-24 too, but got turned dow due to not allowing for a CPL mounting.
Too many choices and combos, but the 16-35 ended as the best compromise among other WA zooms or primes, and the P&S will allow me to be snap-happy while hiking.

If this was a photo shooting trip, then would be a whole different story.
Keep it simple  -  I am trying hard, but it's a fight  8)

In your case, I would bring just the 16-35 along with the 70-300mm.
The 50mm 1.4 would be a bit too much, but at this point why not a pocktable P&S to cover the gap in between the two lenses, or when you want/need to go extra light?

I am still debating with getting the 70-300L or not, but that's another 2.5/3 pounds...

« on: September 23, 2014, 10:24:23 AM »
Don't buy one "to get it all in" the frame as they saying goes.  Wide angles are tricky to use (esp. below 20mm), but once you get them, they result in really dramatic shots.  A quick Google search pulled up a lot of links - I took a look through them and here are the better ones that you might find helpful:

Looks like fake. Front element from 14-24 Nikkor and the rest from 17-40.
Canon will never put a red ring on a hood, it will be on a body, even with integrated hood.

Great catch!

Indeed, a very good point
F4 is ...very pausible, but that front element looks like the one from the Ts-e 17mm
Yeah, the body shell looks sort of outdated, if one compares it with recent WA zoom releases

They might be forced too, which could make these low prices to remain as they are.

The used market that has to catch up too....
