I’ve reached a critical moment in my life. No one responds to me anymore. I’ve tried posting things to Facebook, instagram, and youtube but there’s no engagement there. I’ve downloaded an app on my phone known as Befriend, which I’ve gone without using for about five years. A week ago someone added me there as a “friend”. But the problem with that is, when I message someone, I get instantly rejected. I’ve known hardships in life though. You can’t simply say a thing or a few things and get accepted. The slightest remark that’s not purely perfect gets people riled up, offended, or worse and they don’t want to hear from you ever again. Too bad that I spent my early days at the airport sometimes, which I really regret; seeing all of those people and then they’re all gone is truly and remarkably traumatic for me as an emotional type. So I’m away from the social world.
This lens is optimal for astronomy, observation, and digiscoping!
Askar has been making high quality telescopes. One of their newest items is the 71f Apochromatic (APO) Quadruplet lens, which can be used for terrestrial viewing also. An APO lens is a type of lens that can focus all colors of light into a single point, meaning that there’s little to no chromatic aberration (color fringing, especially at edges of high contrast), creating a view that’s sharper than a standard lens. Quadruplet APO lenses are known to be better than standard APO lenses, because they have some more APO optical components to correct for Chromatic Aberration even more. Although there are various levels of correction of lenses that are APO lenses, this would be the third level, after Doublet APO lenses. The price for this item is relatively low, however, and the focal length is relatively versatile (490mm)!
Camera with 3.1 Gigapixels for making time lapse panoramas of the universe has sensor more than 350 times larger than Full Frame!
It may be really interesting, seeing what this new camera may aid in discovering new knowledge about our cosmos! 3.1 Gigapixels is 3,100 megapixels! So a single image from the camera, with regard to resolution, may be equivalent to taking one hundred images with a 31 megapixel camera. This is all akin to the gigapixel imagery that has been done using SLRs that had telephoto lenses mounted on them (think something like a 250mm lens) to create a wide-angle image of about ten millimeters. I don’t know exactly how Gigapixel images from readily available cameras would compare to a single image from the enormous 3.2 Gigapixel camera with regard to dynamic range and noise performance, but personally, it seems like it may be a very fascinating comparison, if anyone ever does such a comparison!
Entering the 8k Era
Daily writing prompt
You get some great, amazingly fantastic news. What’s the first thing you do?
I would feel more alive and blog about it! What else? not sure but it’s dependent on what exactly the news would be! I need inspiration myself, so such news would almost certainly be something that would make me feel like I should finally feel in life!
Vintage Lens That’s Great For Macro
I’ve been wishing that I could some day obtain a Kiron 105mm lens. It’s been known to be great, especially for macro photography.
Some More Dabbling With Panasonic Micro 4/3
Today I basically coupled various micro 4/3 lenses face-to-face onto my Panasonic Lumix G95; although I don’t currently have sample photos from the setups, I was able to get magnifications of up to about 5X. The lens that worked quite well for me as the main lens (the lens that was attached directly to the camera) was the Rokinon 50mm F/1.2 lens; I used the Viltrox 23mm lens in reverse again, but this time I tried it in front of the Rokinon. This set up created vignette at every aperture; the aperture was adjusted for the Viltrox but not for the Rokinon telephoto lens, because adjusting the Rokinon would not change the level of sharpness of the resulting image. Instead, the Rokinon’s aperture would in such configuration simply be a way to increase and decrease brightness of how much light would be entering through it.
For the Viltrox, I tried apertures of F/5.6 & F/8, but also F/16; honestly, I didn’t see a discernable difference in the amount of vignette between any of these apertures. Not only that, but the vignetting was rather minor; the left & right edges of the midframe were free of vignette. Virtually, the only vignette was near the corners of the frame. I tried zooming in on the frame for analysis of sharpness at the center using the Viltrox/Rokinon configuration; this was overall an excellent result. The midframes were not as sharp though, and I could tell that overall, at all of the given apertures that were examined, chromatic abberation was a slightly evident. The corners aren’t quite as important for sharpness as the midframe and center, mainly because the extremely shallow depth of field would require virtually any scene to be focus stacked, which would result in the requirement to crop out a somewhat significant amount of the midframe.
I had a discussion on Facebook and Dpreview about using a reverse lens technique ; mainly, how such technique may compare with a much more expensive macro setup (the Mitutoyo 5X). What I gained learning from the discussion was that it is possible to get better results with the Mitutoyo objective lens (which costs over one thousand dollars new). However, if you’re someone who may be wondering if the Mitutoyo objective is a necessary must, then I’d suggest to consider what camera you may like to use for macro photography in the 5X range; specifically, try figuring out the pixel density of your camera; the higher the pixel density is, the sharper a lens needs to be to be able to resolve perfectly at such extreme magnification. Pixel density is a relationship, mainly between sensor size and resolution. A Micro 4/3 camera is generally a great type of camera for macro photography mainly because it is easier to achieve a given amount of magnification than it is with a larger size of sensor. That being said though, the smaller the sensor of any camera is, the more likely it is that the pixel density is higher; for example, twenty megapixels of resolution in a micro 4/3 camera in comparison with twenty megapixels in a full frame camera results in the pixels being more crammed into a given space in the micro 4/3 sensor because it is the smaller sensor.
Hi to everyone!
On this beautiful day, I was thinking about making a kind notice to dear readers; you may all (or at least some of you) be overlooking some pretty interesting stuff. “But what stuff?” You may ask.
First of all, photography being a main topic of this entire blog may be one thing, and that’s fine and even interesting to at least some of you, but I was hoping that my more expansive blog may perk your interest even more. Let’s face it: although a single topic has generated a lot of interest, life is complex and so is reality; sometimes you may want to start learning more about a larger variety of things and/or receiving some form of inspiration. Therefore I have also been blogging for my other blog, that is lifeinspiration762.wordpress.com.
Let me know of advice or feedback regarding the blog being mentioned…and remember, life is complex!
My Tripod Got Missing
Every time I used my full-size tripod, I would bring it back basically to the same place indoors. Now, I don’t find it anywhere; outside, in a car, etc. Anyways, my favorite types of tripod heads are those inverted ball heads and Pistol Grips, although some panning heads are great also. I’ve been wanting to get a hold of a specific component which was initially designed for use with a CNC machine; instead of spending about one hundred & twenty dollars for a ready-bought macro slider, I decided that the CNC component could work equally great but at a small fraction of the price of a store-bought macro rail. The store-bought rails are great but they are about three times longer than what I want.
Improving Lens’ Contrast By Physical Means
It made me wonder, if my own lenses aren’t quite that dark, is there a lack of contrast as compared to that of when the dark material that was used in the video?!
