Do not double the aperture, f2 is f2 is f2. Likewise the focal range does not change either. Only the field of view does. Because smaller sensors have a tighter field of view, 50mm FF lens would have field of view of 100mm on a 2 times crop sensor. But f1.8 would be the same even if the sensor was a 2/3" size, 4 times smaller then FF. Why? Because the lens provides the luminance exposure of f1.8 but since its designed for a larger full frame the image circle it provides that light has to fit the sensor, the glass has to be big enough hence crop sensor glass can be so small, a smaller image circle must be covered after all. The only thing that changes is the depth of field, but that is down to aperture diameter in the lens, crop sensor lenses have smaller aperture openings hence less bokeh whereas full frame lenses need a bigger aperture opening despite both lenses being f2.8, their aperture size are different which is what gives you the different depth of field.
Praise be to God for this wonderful video. Hoping to do this trail with my daughter this summer and you show both the highs and lows. Seems like way more highs!
David Yates made the video, not an imaginary friend. Your god is a manmade concept. No god made this, appeared in this, or even had a hand in its making. The praise belongs solely David Yates for this video. Well, perhaps a video editor also. There are no gods.
Ive always seen Jesus As White Trash Evil Meant To Hold The Colored Population Enslaved By The Fear Of Crucifixion 🇺🇸 slavery ✝ ⛓.. And Genocide 🇮🇱 🇺🇦 💀
One of the greatest biking films I've seen recently not only concerning the story but also the direction and the picture quality. Hats off to all of the heroes of that great story!
At age 57 I bikepacked from Silverton to Durango. It was 3 awesome and HARD days. You are so right that the San Juan range is crazy beautiful. 61 now and hope to do all the segments while I can. Nice job!
Jesus love you He died for you 1corinthian15 3-4 Christ died for our sins according to the scriptures and that he was buried and rose again the third day believe in Jesus the Son of God He love you Repent Jesus said whatever you ask the Father in my name that he will do
Why on earth no satellite phone or satellite messaging option. Why are you relying on mobile service only out there??? I mean you do you but even at half your age I would be packing that as a priority. On a positive note incredible effort well done !
Very inspiring and well made documentary. Dave will you so kind and share some of the bike details like brand, model, what air pressure you used the most on those tires, shoes and other equipment if possible. I would like to do some like that maybe not at big and hard like yours but I want to prepare myself as much as possible.
Incredible documentary that makes me want to ride this trail, Ive ridden some of the San Juan mtns (7 days) in Colorado, greatest ride of my life! This is a bucket item for me. I am also newly retired and was diagnosed with a brain tumor 2.5 years ago but have exceeded my life expectancy already. I'm a fit 63 year old and don.t have time on my side. Breaking the ride up was a great idea and would be more manageable for me. Dave, thanks for the inspiration!! Edward
Please can you pray for me? I got locked up in mental hospital because of false accusations from ex family. Many of the staff were surprised I was there 6 months in a hard-core unit when I wasn't presenting any psychotic symptoms like I did a long time ago. They are still force injecting me with their nazi drugs and some of the neighbours and staff here are doing witchcraft hard-core witchcraft I'm still having trouble hearing Jesus voice and presence. Thank you your testimony is amazing God bless 😢❤😊
