Perhaps you need to watch the color of the water in the Niagara Falls photos. The HDR - if you have attempted it it - could be the culprit. The panoramic shots appear washed out & lack pop.

The tree trunk colors are so off. Why?? Have you over done HDR?? Even the greens are over screaming. The first photo has a beautiful composition but lacks the peppy look. If I were using Lightroom, I would reset the photo to RAW or the as shot JPEG. Then use the Clarity & Dehaze sliders. I would play with the White & Black Sliders & finally go to the HSL Module to set the Luminance of the foliage and the green grass + the Blue of the Sky peeping through canopy of the trees.
But first get the tree trunk colors right.

Dear drivingback sir, this is a very pretty photo with an excellent fore ground and background. But there is a color cast to the entire photo. It is difficult to tell when looking at the sky or water, but look at the rocks. That color is weird.
Regards.

Pretty as a Picture Postcard Sagitta Sir. Perhaps the landscape photo will stand out if you crop out some of the excessive foreground dirt.
I have attached a re-done photo & hope you will not mind. I have also made the dirt slightly earthier in color. Of course PP is difficult with a small file size.
Also the rooftops on the houses near the Lighthouse stand out a little bit more in a 3-D effect.
Please see the picture in Dropbox here: https://www.dropbox.com/sh/vxq830jxyu7h2kg/AAAUONQL8dIo7fFg67wYy9rOa?dl=0

Some awesome photos here Tamia!! You brought the "dead" automobiles out from their deep slumber. These shots are music to the eyes.
And when all of us complain how poor pre K-5 DSLRs are, you brought out the glory in your photos with the K200D.
Also the dated Sigma 10-20 EX DC is still a wonderful lens - can weave magic.
Regards.

Looks awesome, kind of miniaturized from the angle this shot was taken. Some very pretty colors too. The composition is eye catching.

Infact this feature is on many lenses: a) lens focus ring moves beyond infinity. This is to allow for precise manual focus. Even over time the lens mechanisms especially zooms become "loose"so that Infinity Focus Mark shifts. b) Consumer Zooms are varifocal. Example for the 35-70. Focus the lens on a distant object at 35mm. Now zoom out to 70 mm. You will notice the LCD preview is no longer sharp. You have to turn the focus ring again to attain sharp focus.
So some lenses will will show two Infinity marks clearly, one at 35 mm and the other at 70 mm.
c) On some lenses you will see two vertical lines in two different colors against which the distance markings line up. The one with a slight shift from the central marking is used for Infra Red Photography. Infra Red Light Wave Length and normal or plain light focus at slightly different points.
I have the older Sigma 10-20 EX DC f4-5.6 (no HSM) but has AF. There is only one Infinity focus marking on the lens barrel denoted by the inverted "L" symbol.
Just an aside: Last October we were in the Canadian Rockies, specifically Calgary - Banff - Jasper and the Columbia Icefields with the awesome glaciers. The weather was nasty - extremely cold - snow, sleet, rain, fog & mist. My lens would not move upto Infinity. So I would focus manually. I thought the lens was broke. But when I travelled back to San Fransisco it was working pretty well and focusing to Infinity. I am still left wandering at this strange behavior.

Beautiful photos with a perspective and a view. And some of the best reflection photos from those massive glassed in offices.
The IT / Computer Parks here in Bangalore have some pretty offices similar to the ones you shot, as Bangalore is India's Silicon
Valley and a partner to Silicon Valley, California.
Keep shooting JibbaJab.

Hello JibbaJab, so kind of you to have responded. My daughter lives in San Mateo California and my son in Thornhill, Ontario, Canada. They are all citizens of the respective nations. I am an NRI, that is a Non Resident Indian, having worked abroad - USA, Scotland, The Middle East, North Africa & the Russian Federation. I retired as an Advisor, Nissan ME, N.Africa & CIS.
Here are some photos on our Dropbox link: https://www.dropbox.com/sh/sxea46nwm03y2y7/AAA87EzC3PlgK3CfTjxBAEc-a?dl=0
From the one full family picture you will understand all the rest - Anamika (33): L to R - daughter Anamika, her daughter Anya, son in law Renchi, self Bipin, wife Madhuri, son Amit, his daughter Anika, daughter in law Namrata. And the girls holding hands in Los Angeles are Anya on the Left and Anika on the right.
No wonder you addressed me as "ji". How beautiful is our Asian culture. "JI" is used after a name for respected elders in India. Thailand, Bangkok, Singapore, Malayasia, Bali, Indonesia, Burma are all replete with Hindu Temples and Hindu culture and dances from our holy granth the Ramayan.
God Bless and take care.

My Compliments to JibbaJab Maam. I think I shall be a grandfather to your pretty children as I am a "Nana" to a pretty Anya, my daughter's daughter, and "Dada" to naughty Anika, my son's daughter.
We don't use a generic "Grandpa" in India. I spend a lot of time in North America - San Mateo, CA & Thornhill, Toronto, Canada. Where are you in California?
God Bless.

Thank you, NS_Sailor Sir & JibbaJab. That the lens needs a CLA is a foregone conclusion based on your observation of dust on the gears and the grease thickening. 5-years is a long time. Just that I have used this lens very carefully, avoid changing lenses outdoors and keep my gear very very clean. After each major tour I clean the lenses and camera body with a British make painters brush (not Chinese cheapo), a massive Rocket Blower, a soft tooth brush (especially on the rubber grips) and a Japanese Micro Fiber Cloth.
Since the lens alignment, centering and collimation are a prime concern on SWA Lenses it has to go to Sigma Japan.
Many years back while researching use of a SWA Lens I learnt: a) Fog & haze prevent auto focusing to infinity by reflecting back the light and not allowing it to travel through the haze to distant objects like a mountain range. So the lens never reaches the Infinity point.
b) Beyond the first few meters, ultra-wide lenses tend to take a guess at focus. So the lens may not reach Infinity and that doesn’t help with sharpness. Manual focus can often be a better way to go. The main thing is to decide on the visual centre, and focus on that. DOF takes care of the rest.
Lovely children, smart and photogenic too. Thanks for the post JibbaJab Sir.
Regards.

Kentster, Site Supporter Sir, awesome trio of photos from the Hoover Dam. We visited this site on our way to the Grand Canyon from Las Vegas last December, so we can truly enjoy it.
Please note that we cannot view the photo in its entirety and have to scroll. This looses the impact of the Sigma's wide magic.
Or is it a problem with my 4K laptop?
Regards.

Hi Mike, is this Lombard Street and Montclair Terrace looking up?
Google street view attached.
Looks like a daylight photo and to that extent the night time magic is lost.
Wonderful star burst. Was this using a star burst filter or??

Hello mkyyy, be warned of the use of filters on this lens:-
a) vignetting unless you use a slim frame filter
b) massive lens flare. remember there is a huge surface - 77 mm diameter of glass on that filter. Also this lens pulls in a lot of sky whose bluish hues can change
from the center to the sides.
c) multiple green colored reflections under some photo situations.
d) loss of contrast, color and sharpness.
Regards.

This shot of the SF Cable Car is a technical & compositional marvel Mike. Very pleasing. In spite of spending some two weeks in San Francisco split into five occasions, I have never got a successful shot of the Cable Cars.
Request please share how you captured this extremely sharp shot in low light as the car was being turned around. Gear used and exif data will also help.
Like I can see no people or tourists are around, so perhaps you used a tripod as the buildings are very sharp too. The moving trail - horizontal swirl lines - with the posters and the vertical posts to the bottom LHS are a mystery too, as I don't recall seeing one on the turn table.
I am very familiar with the location - end of Powell Street abutting Market Street, where we queue up for the Cable Cars.
Regards.

OH my! Kengoh Sir, the Singaporean Chinaman weaving his magic with the Sigma 10-20. Hats off to you Sir for giving us these awesome shots.
I am certain Singapore being so tiny and so familiar, you can shoot with your eyes closed now - I mean not one eye, but both closed.
I once stayed with a royal family in Serangoon Street and enjoyed the ethnicity and uniqueness of that place. Do give us some shots from this place.
Good luck. Keep shooting.

Such an awesome shot of Downtown Philadelphia Designosophy Sir. Try as much as I could I am never able to get such perfect verticals on architectural landscapes of tall buildings, towers and spires with my Sigma 10-20.
I am tempted to say - tongue in cheek - with 56 years of experience - that this photo has undergone some kind of PP - HDR like editing, sharpening, clarity, shadow correction, straightening of the verticals and or lens distortion correction etc.
Look at the strange greens, blues and the browns + yellow-browns of the walls. I have visited this place and cannot quite relate to the colors. Of course my vantage point was at street level.
Sorry for my comments as I could be off the mark. But I do have a forensic photo software that can undo PP and point to some changes made to an original photo including malware hidden within the JPEG.
Regards.

Googled MT 9-18mm zoom lens, but came out with just the Olympus M Zuiko 9-18mm ED Lens.
What is this MT 9-18 ?? Russian or German or Korean brand ??
Can you post a side by side photo of the same subject taken by both the lenses.

Doundounba Sir, I am unclear on your take on flare for the Sigma 10-20 f4-5.6 EX DC Lens. Do note, even the best lens in the world will demonstrate some flare if pointed to a bright light source. Only a comparitive testing demonstrates how much flare and what is acceptable.
As I said, I read the SWA Lens Flare Test some 3-years ago, but I will try to search for it. Xavier Guiterrez is an auyhority on this lens. Do Google.
I too get a color streak with my lens at certain angles to the sun - a rare phenomena, which I am told exists with SWA lenses. Also when this lens was released by Sigma, close to 50% had one problem or the other. Later Sigma tightened their Quality Assurance & Bench Test.
Regards.

Perfectly put dcBear78 Sir - What Flare?
The Sigma 10-20 is a superb lens. I read some 3-years ago on the internet about flare tests done on some 4-lenses using natural light, street lamps, neon signs, car headlamps etc, and the Sigma came out with flying colors.
This is the best lens for the money - period. Ofcourse every one will have their opinions, but I request you read up comparitive test results on the net.
And I am sorry for you if you have a bad copy - every lens has a manufacturing tolerance, and sometimes they go awry.
It takes some time to master and tame this lens - took me 5-months.
Happy shooting.
Regards.

I am certain my K-5 and the Sigma 10-20 f4-5.6 EX DC does a much better job both in sky and ground color + is brutally sharp, so much so that you can see each stubble on a man's face when blown up 100 %.

Excellent photo of a legacy Cast Iron Slide Narual Sir - captured for posterity. Good perspective too. Some side shots would have helped complete the picture story. Also the HDR effect is too strong, perhaps a little overdone.

Making flowing water look like gaseous vapor steals the natural beauty out of a waterfall / stream / nature / outdoor shot. But of course choices are very personal.
