DoF ~ focal length * aperture * subject distance
If you want to shoot the same picture using the same lens with both FF and crop sensor cameras, you need to be closer to the subject with FF camera to get the same framing and that's the only difference.

this is really it... good simple explanation...
 and badgepiper added  a bit more....

to get the same framing the move closer on FF...
and closer....shrinks the DOF...
in basic terms...

this is all you need to keep in mind .....IMO....

Lenses / Re: 50mm Primes that don't suck wide open?
« on: July 11, 2013, 04:13:09 PM »
In preparation for my upgrade to a 5d3 (from a 60D) later this year I'm trying to compile a list of potential prime lenses to get between the 35 and 100mm range. I've already got a 24-105L and will sell my non-L 70-300 to get the L version. Also have a 50mm 1.8 so I'll need to get a 85 1.8 to get my portrait capability back.

Then the question remains: Do I keep the little plastic toy (which never use wider than 2.8 anyways) or just get a pancake (which is actually pretty usable wide open, vignetting aside)? Do I even need a 50? I know the 50mm 1.4 isn't great wide open either and has fragility issues but at least it'll work with the automatic CA corrections in the 5d3 (I shoot RAW+jpeg). The sigma 50 1.4 is...really big for a 50mm prime, has AF quality control issues and won't work with auto CA corrections. Rumor mill has it that the sigma 50 is due for a rebody to the "art" line they've got going now but probably won't get an optics refresh... Oh yeah, the 50mm 1.2 is a no thanks I'll keep the money. Everything 50mm seems to be a compromise and you'd think after so many decades of people using such a prolific "normal" lens the designers would have perfected the formulas by now.

Do I even need a 50?

I have the 50 1.8 ...ok in a  pinch I suppose...

but.....NO ....skip the 50mm.....I never found one  that I liked

get the sigma 35 f1.4 ...
this is a VERY good 'normal' lens..
it is just GREAT wide open
sharper than most other lenses ...wide open
clean...from most aberrations..

I just went for a walk with what I think is essential......
an ultrawide 14L II (or choose a 16-35 II)
a sigma 35 1.4....really good value and sharp...and it pops the shots....
and a 100mmL macro (or choose the 135 f2)

add a 12mm tube and a 1.4x TC (a tamron fits the macro or the 135L)  - especially with the 135L ,

and insert your .... 5D3

love it all

I have the 24-105 (nice lens) if I only want ONE lens.... it never fails to please....24mm is pretty wide already
and....I also have a few specialty lenses ...85L II, 70-200 f4 I.S., 70-200 f2.8 II.... 24L (mk 1)

but the three basic lenses (100L versus 135L decide)
are enough to do the typical stuff...

start there


Canon General / Re: Lost inspiration
« on: July 11, 2013, 08:41:48 AM »
I have just moved continent, from Asia back to Europe. We've been home for just about a month now and I have barely touched my camera since. As my identity here indicates photography is a hobby, not my profession. I normally like portraits and street/travel.

Before we moved back I showed my pictures at a local gallery which was great fun, I even sold a few prints. I spent a lot of time preparing that show and shooting and shooting to get enough material. Maybe I got exhausted from that or maybe it is like a journalist friend of my said the other day: 'Transition kills creativity'. Maybe I have higher demands on myself now and am afraid to take bad pictures.

I hope to get it back soon enough though. I just wanted to share this with you guys here. Any thoughts of course are welcome. Do you lose inspiration sometimes? What do you do to get it back?

I thought I had taken ALL the pics of my town......
and rolled to a halt...

I found if I get out for a walk the up some people...
I see new stuff...

I pushed my creativity out taking  a fast lens (35mm, sig 85L) out in early morn sunrise ... and also an ultrawide angle..14mm......
these make me see more of what I missed in my seeming boredom....

just a thing that helped me

I mean if I was suddenly in Paris it would be easy...but in familiar digs.. you need to look around again

try the early morn thing is happening in a diff way there
...I liked dilbert's idea..above........get a theme...yes that's it..
the am morn thing was a theme for me...get more themes...

then collect the best theme shots in folders and give yourself a show.. to check progress
good luck

Third Party Manufacturers / Re: sigma 120-300 new and old
« on: July 10, 2013, 07:26:40 PM »

I sort of thought the new one was ..almost the same... wait for a test..
but the 300mm is a bit short...ok

I really cant see the big prices for the new 200-400 +1.4TC

it is SURELY a fine optic..
I can see a couple acres in southern Oregon  a better investment...good grief!
this only because I am not a pro in need of the top thang..

I see it ...if I was

thanks for a little info on the sigma

the 135 [...] has a little better quality bokeh...

This is a huge understatement.

ok  ok....the 135 is wonderful... I like it better than the 85L II....  it is way at the top...I agree
but the macro is good too...
no it does not win the contest....   neither does the 70-200 f4 or f2.8....but they are fairly good...

thanks for NOT letting that slide.....

in my 14L, 35 sig and 100L/135L  triad...... the bokeh on the 14L is ...well ugh... but I dot use it that way.
the sig 35 1.4 is  not perfect, but nice and is so sharp wide open that you forgive a little busyness there...
the 100L macro is pretty good but no prom-queen....
THEN the 135 just coasts on thru....on that set...

yes it is a lovely optic

but I am taking the sigma to the is so useful to have so sharp, and clean at the 'normal' range...  sorry Canon...dont miss my 35L anymore

(I dont use 50mm)

Lenses / Re: Just got my 135L!
« on: July 09, 2013, 01:58:30 PM »
I was debating purchasing a 135L - actually placed an order for a refurb at a great deal with Canon but later changed my mind and canceled it... reason being that i already own the 100/2.8L and 85/1.8. Reading owners comments on both 135/2L and 100/2.8L it seems like the two are pretty close in terms of image quality but 100/2.8L is more verstile with macro focus ability (135 min focus distance is 3 ft) as well as IS.

Anyone who has owned both could comment on both these? DO you agree the two lenses are pretty similar but with 100 being more verstile?

I have a llot of good lenses..
theh MAIN ones I want to take out..
are the 14L II, 35 sigma and then EITHER the 100L macro or 135L f2..

so to your question ...I have a tough time deciding..
the 135 gives faster aperture...for lo light, takes a 1.4x well  and has a little better quality bokeh...
seems more useful
BUT the 100 L  macro is quite good and if I.S. is needed in the goes ...instead of the 135

so you see is a toss-up ...unless I.s  versus f2 speed is a decider...

I am a stop and shoot the flowers guy so the macro 'draws more water' with me...
but some days I take the 14L 35 sig and 85L II(or maybe the 135 f2) JUST for lo light, first-sun AM shots..
tha macro has no standing on those moments...

cant lose... just choose

and I await the NEW SENSOR/focus tech...70D...and then FF
... and these new options with the SAME FREAKIN LENSES....go Canon!!!

I bet
if macro is not so important to you ...then 135 f2 and a 12mm tube is fine...
I.S. is a helper ...not a decider... I suppose


the real news is..... the sigma 35 1.4 is sharper than any comparable canon ...wide open...
man....I love it....
pair that with a 135 f2, (or 85L II) and you have a serious lo-light kit....add a 14L for some spicy flavor


EOS Bodies / Re: So I made the jump to FF - now what?
« on: July 07, 2013, 07:03:14 PM »
not knowing WHAT you like to shoot

for me...I have a bunch of lenses..
and I regularly RETHINK what I NEED to do things..

I would say the number one lens used to be my 100mm macro (both versions were owned)
BUT the fav lens is the 35mm sigma f1.4 ...I would skip 50's and get this first
it will define low light shooting .... I am very sure USE of FF is realizing the wide-angle..
SO... immediately after financial recovery...
get either.. a 14mm II (expensive) or a 16-35 II......(almost as expensive)

finally for a little reach ...either a 135L f2 (with a 12mm tube), or the 100mm macro..

or for bigger reach.... a longer zoom like 70-200 f4  I.S. or f2.8 II... both are the tops...
those zooms get pretty useful for sports/action ...and even portraits...
but I would put that option down lower on the list... normal (35mm) ....and long/fast prime... CARRY-ABLE stuff

all the rest are very specialized ... and IMO... less needed..unless YOU are specialized...
then you NEED THEM

MAYBE 14mm II, 35mm Sigma  and a 70-200 f2.8 (1.4x TC too) if you really want all that reach...

I could see starting with a 35 sigma and the 70-300L as mentioned
as the only two at first .....THEN an ultra - wide as $$ Permit...

I enjoyed / owned a lot of the good lenses but I come back to these limited choices...especially when I have to carry them anywhere

I admit to a 24-105 zoom as a staple..... a very good one... but the 'edge' comes from the primes...IMO

by the way
I dont use a tripod and seldom use a flash.. but weddings and such etc would need the flash

just some samples from the fav lenses

6D is supposed to be sensitive...that would really work the sigma 35 f1.4  nice and hard...

enjoy the camera...dont miss 'wide' experiences...


a lot of manage

thanks for this useful forum

now my most used spot


may I suggest the finest FACE lens-VALUES for canon.........  will be the 35 1.4 sigma...yes a bit wide....
but it gets ....close and is inclusive of the scene...sigma 35 ...better than the canon - I own both
perfect - full quality - wide open if you want or need it.... a crazy good lens... I like it more each day

and 135 f2 canon L...again.... perfect wide open ....beautiful piece
for ...longer and strictly a good face...
maybe 85LII it to death.......  but more $$

I do not care for the 50L... for any of this...
just my idea

14L II, 35 sig, 135 f2(sub 85L II if you want) ...all you need (one tube and a 1.4x TC for 135)...that's it


2 samples of 35 sig, one each of 135L and 85L
add a 14L II and

Lenses / Re: Is the 16-35 L II worth its price?
« on: June 06, 2013, 04:09:20 AM »
I had the 10-22 canon on crop sensors...loved it

thren got the 16-35 II when I moved to 5D2...
loved it.. it was very good...still have it with 5D3...
but I got the 14L II and love it more..

the 16-35 is still useful when I have a small kit ...
like a 16-35 and a 70-200 ...or maybe just with a 100L macro..
the zoom covers toward normal..

but for me if I want the best..I use the 14L II..
fits nicely below the 24-105 (or 24-70 II) ...or just a great prime like the 35 sigma...maybe add a 135 f2L...

14mm is wonderful..
I guess 50% more for that one..

the 16-35 actually has lower chromatics/fringing than the 14L II...this is all correctable
14L sharper...over all...and  to the edges...for sure

is 16-35 worth it attention to your copy to make sure it is good... IS worth it - IMO


Lenses / Re: If you could only have three lenses...
« on: June 03, 2013, 08:28:10 AM »
this is awful...

I am about to face the reality though

14L II,  35 sigma and then EITHER  135 f2 (w.1.4x and tubes)  or 100L macro.

I would miss macro or closeup ability... and I would long for f2 aperture...
but I bet I choose the 100L macro...just too  'able'  a lens...
14L, 35 f1.4 sigma and 100L macro..

that will leave a LOT of lenses packed away....WOW

if only ONE lens ....or a forth lens.....I would add  my 24-105 versatile
if only TWO lenses......14L and 24-105

long is not quite as important to me as aperture ....and ultra wide

what is the difference between this lens

and this lens

Lenstip liked the new one....

it seems that one could confuse these two..
except for the price difference

what has changed?
did I miss something ?

I do notice the different looking BUILD

thanks for help here


Abstract / Re: Beautiful bokeh! Let me see yours!

the sigma 35mm @ f1.4.... 5D3
I sold my 35L (which I liked)  and bought this lens

first shot:
daughter in-focus
the woman(mother) - on the left - in the background is a good example of a nice bokeh quality - to my eye...
the guy in right corner is pretty nice treatment too

of course the quality varies  with differing back ground distance and foreground focus distance
and of course different busy shapes too....  the sigma is not tops...but pretty good IMO

this just seems to be an ideal combo for the sigma 35......

second shot:
different the stove-hood on left ...the lines start to get slightly busy..  the 85L would likely handle that differently
I believe...all this is pretty subjective...


lots of nice examples in this post
people here have really nice compositional ideas too...

I would say the 35 sigma and then - either - the 135L or 85L canon are a great pair..

the sigma is sharp wide open, has minimal distortion and chromatics,
 is built solidly and focuses accurately and quickly .... it is a wonderful lens -  IMO


Lenses / Re: Standard Lens for Paris and London holiday.
« on: May 27, 2013, 02:11:23 PM »

you think I am over reacting....?

I found London to be very safe been there a lot...
My brother lived ther 35 yrs..I visited regularly....felt at home

just a few times to Paris...LOVE it.. but there is a known thread of thieves as I described....
I stand by my report

the issues I described were also described by a number of posts I read...upon return and asking about other's experiences...

packs opened in 3-4 attempts ... zipping a bit at a time...
by trailing pair of thieves - one at watch - one behind the tube or a crowd

so I believe Paris is a bit more risk.... and recognized as such.

but I am not an expert.....I defer to your expertise on Parisian/London Crime ...
me...I will stay alert....more alert in Paris


Lenses / Re: Standard Lens for Paris and London holiday.
« on: May 27, 2013, 09:36:59 AM »

I use 5D3 ...

I already have the 16-35II, 14L II, 24-105, Sigma 35 1.4, 100L Macro, 85L II 135L, 70-200 f2.8 II and f4 I.S. .....
and tried the 24-70 II ... returned it for softness at 70mm....but may get it back.......  yes too much...I love them all

so what would I take to Paris / London  ?
my general plan was to make up THE most able and smallest kit for travel and/or home (I have too much gear)

the FIRST PLAN -  WAS  -  to have the 24-70 II ... THEN add the 135 f2 ....small and capable
and THEN add the 14L II  ..... get the WHOLE bridge in the shot

but then I tried the sigma 35 1.4 - wow....gotta have it on every trip now...

so ...adjusting
FIRST - I would NOT go to Paris without an ultrawide - for bridges, buildings, even museums -  end of story...

SECOND - for night or weak light
one needs a low-light walkaround that WORKS - the sigma 35 is PERFECT ... cafes, portions of lighted bridges, nicely framed day scenes
then a bit of low light 'reach' - the 135 (1a 1.4x TC still yields f2.8)

so for ME...I would take the following ...adding EACH new lens ... as I accepted more space/weight requirements

first - if ONLY one lens - the 24-105 is it... in a small single case ...and 3 batteries and a 3-4 VERY large cards or offload laptop ability.

if ONLY two  lenses ..... 16-35 II and  the 135L (for me I would cheat and take 50 1.8 ).... for you... take the 50 1.4
(so you already have the Paris kit)

if ONLY three lenses the 14L II(or 16-35), sigma 35 and 135L - that set is crazy good quality...very good low-light
if a FORTH lens is ok, THEN GET THE 24-70 II (and no 16-35 - stay with 14L II) .... at this point you have 14L II 35 sigma 135L AND a walk-around zoom - 24-70 .... all world-class optics
a 4 lens kit should do it ...add a 25mm tube and a tamron 1.4x sp pro
(a tamron 1.4x on the 135 L gains a little reach - with very little loss in quality or speed)

I cant see 70-200 (f2.8 OR f4) as a travel lens in cities


my conclusion for you is - you have 16-35 and 50mm and 135L
this will do almost everything.... just use them....
I would swap the 50mm for the sigma if any change at all.... the sigma is as good @ 1.4 as the 50 is at f5.6 IMO - a killer

you could walk around the city with 16-35 all day ..ultrawide to near normal
I used 10-22(same as 16-35)  for 90% shots in Chicago over 3 days

I sometimes go out for long city walks with the 16-35 and a 100mm street fairs etc.. gets me close and wide... and fast enough

one more thing ... in PARIS especially...
keep your kit VERY CLOSE -  I would run a little cable/lock thru the zippers on a back pack or carry in my front...
the little teenaged thieves are very clever and work in pairs in Paris... they partly unzipped our back pack TWICE at train station entrances ....EVEN when we knew they were there...

just my thoughts
