One of the most useful lenses any photographer can own is an ultra wide-angle zoom lens. One of my favorite zooms in this category is the Tamron 15-30mm f/2.8 lens. Tamron recently released the. Nikon 24-70mm or Tamron 15-30mm or Nikon 14-24mm. Spitz2400 Posts: 7 Member. The 14 - 24 is a completely different specialist lens it is big, expensive will not accept 77 mm filters I am very finicky. The Tamron 15-30 is huge, huge, huge! Share on Facebook Share on Twitter.
Issue - Tamron 15-30/f2.8 - Sigma 35/n1.4
I'm well in to the procedure of converting from shooting cropped to complete body for astro landscapes. Been carrying out astrolandscapes for about 3 yrs now. Going from a Pentax T5 (16mg) with a Sigma 18-35/n1.8 (furthermore making use of the 0-GPS1 AstroTrace) tó a Pentax E1 (36mp with AstroTracing) and the issue being posed here will be the lens (exact same sensor as the Nikon Deb810). Right here is definitely a bit of circumstance for what I'm carrying out.
Feb and Mar marks the come back of the Milky Way core. It goes up - installing pretty toned across the horizon from North to Southerly. I would like to take it once again. Last Feb, I went to a new site (Picket Article Hill because of thé windmill for foréground interest) and it switched out properly, but got a few of mistakes - my hands with hand protection were too iced to actually run the settings to start capturing in monitoring mode with the GPS AstroTracer - so the above link has been simply my initial 13 second publicity across the heavens.
As of today, I possess about 70+ days until the last two weeks of February 2018 which will indicate the come back of the MW primary (yup - I've examined everything TPE fór the moon ánd Stellarium for increase moments and directions, along with the maximum level of increase that the MW primary will attain). I have got the E1 body and have got chance the MW last Sept and nevertheless training with it to get the procedure down (it'beds a bit different than the E5) - fantastic resolution, colour, contrast, basically my goals. If I were to possess to take tonight, I would use the Sigma 18-35/n1.8 (cropped lens) but it will cover a complete sensor at about 25mm @ f1.8 (with the hood taken out) relating to (with pictures - simply scroll down) fredmiranda's link below.
. ánd that may become an option. But, that's my go to battle position - you take with what you possess (my FA 31/f1.8 Small has some coma I have found).
Queries
I'michael currently considering two lenses as my major astro glass, and I have got some queries for anyone who has chance with these - especially capturing the MW. I'michael really curious if somebody has shot with both óf these. I possess read reviews, specifically from folks who have got chance astro with thése.
- Pentax DA 15-30/f2.8which basically will be the exact same as theTamron 15-30/y2.8- This will everything nicely, compares extremely positively with the Nikon 14-24/n2.8. I would including to shoot this across the entire focal variety. When I put on't need to capture straight up (90 levels) straight down to the horizon (0 levels) which 15mm would perform, I can zoom to 30mm and shoot a reduced view, but would basically enhance the resolution of the captured image. The actual question here is how does the 15-30 capture @ f2.8 @ 30mmeters likened to the Sigma 35/f1.4 ceased down to y2.8 to remove coma.
Sigmá 35/y1.4- This would gather an massive quantity of lighting, specifically when used in association with tracking, I would have all the light I actually need (I amount about 10x what my E5 captured - FF with tracking @60 secs). In reading I have got arrive across two differing views - both centered on astro encounter. One (1st link) indicates that the 35/f1.4 offers coma also in the center at f1.8 but it will go away when you stop down to y2.8. This is certainly a 2017 evaluation - really current. The 2nd link (2013) comes anywhere close 4 lenses, with the 35/y1.4 coming out on best and is usually graded 8/10 on coma. My delima is definitely that if I require to end down to f2.8 to clean up coma, after that this is usually a mind to head assessment with the 15-30 at y2.8 - why is definitely this a competitor, I might as well go with the 15-30?
0verall, with stitching, and I'meters stitching wide (over sewing), I feel essentially just making use of about the middle 50% of each framework, removing the edges and all the corners. With the sensor't size (7360x4912) in top to bottom positioning, my causing pictures should be on the purchase of 20,000 back button 8,000. I would including to print out it at 20'back button30', but furthermore have got an idea of 20' x 60' if it really all functions as anticipated.

I actually only wish to purchase one lens. Right right now it's the Pentax De uma 15-30/f2.8 since I should end up being able to use it across the whole focal length variety at y2.8 with basically no coma and superb CA. The back-up is capturing the Sigma 18-35/y1.8 at 25mmichael f1.8 which would basically obtain me quite much the exact same watch as on the crop body - but with abóut 10x the amount of light (FF and monitoring) and double the resolution.
I possess re-conned a quantity of places that offer topography variations of this photo (Picket Blog post Mt). I possess right now about 5 places and looking at out however another one particular. I would really like to star them all. Now that I have always been retied, I really would like to function the night for these final 2 days in February shooting each of these areas and just star the outcomes. But, I also have enough period to reshoot - provided clear Arizona heavens.
Been doing the study and homework - but what will actual field experience present?
Thanks a lot for everything in progress!!!!
