First Florida Birds in Flight Workshop Update

I’m headed off to SW Florida for my second bird in flight workshop but wanted to give you an update on the first one. On this trip, I used the Sigma 150-600mm Contemporary lens exclusively. Why? Its lighter weight than the Sport really makes it easy to hand hold, even for each 2&1/2 hour session […]

John Marchegiani - I have a Sigma 150-500 lens. Is it worth the money to upgrade to the Sigma 150-600 contemporary? I use the lens mostly for wildlife photography. I have a Canon 70D.

Roman - Absolutely! There is a significant improvement in both the AF and OS from that model and you should get around $300 for the other lens.

Jean Allgood - Do you mind if I ask what camera setting you use to photograph birds in flight? I have the Sigma 150-500 on Canon 7Dii and use AV wide open. Eyes and most of the bird are sharp except for wing tips.

Also, I take many pictures that usually turn out (partly due to my Sigma and cameras now take pics so rapidly) so I’m 3 yrs behind. What method and software do you use to go through them more quickly and how do you edit?

Thanks so much and I just discovered your site today and will explore it further.

Roman - Hi Jean, this video will explain all my settings:

Stephen Sinksen - Hello Roman,

I just watched your “paradigm shift” video. Great information!!!

I have one question – I have a Canon 7d Mark II and am considering getting one of the Sigma 150-600 zoom lenses and the 1.4 TC. My understanding is that anything slower than f8 I will be limited to manual focus. This combination comes in at about f8.4. Is there any chance I will still retain auto focus?


Roman - I have that camera body and it does indeed AF at f/9 with our new TC 1401… guarantee with other TC’s.

Yellowstone/Tetons 2016 Workshop Report

This was my 16th trip to Yellowstone NP and I have to say, it never gets old!  This year, my workshop was a bit different, as I had to adjust the schedule for my tours and keynote presentation for the PSA conference. As luck would have it, the schedule change and weather patterns coincided to […]

New Year/New Passion

    Happy New Year!!! My boys, Greg and Ian, have traveled with me extensively in the US and Canada.  They have had the privilege of seeing some of the most remarkable places on earth but we haven’t had a “family vacation” in a long time.  Why?  Life, kids sports, family commitments. finances…..these are things […]

Susan Candelario - Loving all of your aerials, Roman!!! Even though what happens in Vegas stays in Vegas… I’ll break the rule this time 😃 and say what I told you there: There is nothing that you set your sights on, or that is thrown at you that you don’t achieve and excel at.
We had an awesome time photographing with a real friend a pro photographer in Sin City!!!
Happy New Year Dr. RK and to the whole gang. 😁

Sigma 150-600mm Comparisons

A recent article on a popular Nature Photography forum about the new Nikon 600mm prime really drew my ire when he dismissed the Sigma 150-600mm Contemporary and Sport (as well as the Tamron version) as “entry level” wildlife lenses. I have used the Canon prime 600mm so I can very easily compare the quality of […]

Steve - My Sigma 150-500 seems really soft to me. How do these new lenses compare compare to my old lens?

Roman - Hey Steve, I did a blog for Sigma on that lens: so not sure but some poeple I know have sent itinto service with their camera body and the repair dept did adjustments to it internally…..and that seemed to help. That being said….the new OS and drive motors are the newest generation…..hence making it faster and better performing than the 150-500. Remember….there is a 4 year warranty so you should still be covered. Hope this helps.

Roman - and if you look through the blog…..there are a number by me featuring the new lenses:

Cynthia - Hi Roman, First, let me tell you how much I LOVE your photography. I recently purchased the Sigma 150-600 Contemporary lens, along with the dock. Must admit, I am going through a steep learning curve. My goal is to take as beautiful photographs as yours. Thank you for this great blog–as I shoot with Canon, and all of my glass is “L” series. This is my first third party lens, and must admit it’s build is fantastic for a $1000. lens.

Roman - Thanks Cynthia and with practice….you will master that lens for bird photography!

Konstantin Georgiadis - Hi Roman, I have recently determined that my 150-600mm C mounted on my 7D Mk II was backfocusing. The method I used was very empirical, i.e. placing 5 AA batteries close together at a 45° angle on a flat surface and focusing on the lettering of the middle battery. Based on the results, I made a 1-click correction with the USB dock and sharpness has improved but I am wondering if there is a more accurate/quantitative method to determine how much of an adjustment is needed so that I can optimize my body/lens combo. Thanks!

Iceland 2015 Workshop Report

Since I am home for a month I figured I could play catch up on a few blogs and announce the spring 2016 Iceland workshop! As usual, the Icelandic weather gave us pretty much everything you could imagine including a few totally clear days, which is a first for me! You really can’t help but […]
