leica dream Posted February 21, 2015 Share #1 Posted February 21, 2015 Advertisement (gone after registration) I use and very much enjoy the huge range of the lens on my V-Lux, but rarely use the full 420mm option especially when hand holding. I shall keep that camera, but if I were to get another with, say, a 35mm set prime lens, would I be able to achieve acceptable results by cropping images in PS as I would have got by using a longer tele setting on my V-Lux?

jaapv Posted February 21, 2015 Share #2 Posted February 21, 2015 Depends on what size you want to display/print them. For Internet/phone display the crop will be fine, for larger prints you will lack pixels. I suppose you are not talking about hand-held 420 mm shots with a light camera. If so, anything will be better. Link to post Share on other sites More sharing options...
stuny Posted February 21, 2015 Share #3 Posted February 21, 2015 Jaap - I sort of disagree with you about handheld with a light camera at long tele settings. If one uses the same "steadying" techniques as firearms target shooting there is little difficulty hand holding at "420." In fact, my V-Lux 114, in "smart" zoom extend is the equivalent of 800 mm. Here's just one of many examples from our recent trip to Nicaragua at "800." I do agree with you if one is unable to handhold at long tele settings. A disadvantage of cropping, beyond the loss of pixels is that with the short lens you may not see focus or movement blurring until after you crop. Welcome, dear visitor!

leica dream Posted February 21, 2015 Author Share #4 Posted February 21, 2015 I too risk hand hold at long focus - but rarely. If I do not have a tripod with me I seek something to lean against or rest upon. I think what I am seeking is reassurance (or otherwise) of advantages/disadvantages of a short fixed prime lens. The idea is to get a smaller camera to carry for more spontaneous use, but I need to understand what flexibility I shall lose by choosing such a model. In fact I would think it would be very rare indeed, if at all, that I would want to shoot for detail at long distances in those circumstances.

giordano Posted February 21, 2015 Share #5 Posted February 21, 2015 Here's an image shot with 3 lenses: 200mm full frame, 50mm cropped to 1/16th of the frame and 20mm cropped to 1/100th of the frame. Looking at it another way, if you have a 35mm lens on a 16 MP camera and you crop it to match a 135mm lens, you will only be using the output of just over one million pixels and throwing away the rest.

Well, at focal lengths over 135 I like the heft of a solid camera and a heavy lens. Even then I prefer to use a pistol grip, chest pod or beanbag.

Herr Barnack Posted March 13, 2015 Share #7 Posted March 13, 2015 Advertisement (gone after registration) Depends on what size you want to display/print them. For Internet/phone display the crop will be fine, for larger prints you will lack pixels. I suppose you are not talking about hand-held 420 mm shots with a light camera. If so, anything will be better. True. That is why I always strive for a full frame shot. Shooting with a camera that has a 24x36mm sensor and then carving off big chunks of the image afterword is self defeating IMO. Sometimes cropping ends up being necessary but if you can do your cropping before you release the shutter, you will be much better off in terms of image quality when you make prints.

adan Posted March 15, 2015 Share #8 Posted March 15, 2015 Let's just say it also depends on the camera and the lens used. I was rather amazed that using - an M8 with a largish sensor - an M8 with no AA blur filtering - a raw .DNG original - and a 135 Tele-Elmar at its best aperture (between 5.6 and 8) ...I was able to crop for about a "540mm" field of view - sharp "to the pixel". (135 on M8 = "180mm" x 3x crop = "540mm") It WAS for web use (actually to be a still in a 1080 HD video). And it was not shot originally with the idea of cropping - it was an editing choice I made in putting the video together a couple of years later. Today I own a 400 on a Canon 6D, and would use that by preference if I wanted this picture. With a little cropping if desired. To meet forum specs, this image is reduced from the cropped original 1300-pixel width to 900 pixels. And of course jpg-compressed. The inset shows the full original M8 framing. Welcome, dear visitor!

jankap Posted March 17, 2015 Share #9 Posted March 17, 2015 Super! Changing lenses would not have been possible. The result makes it. Jan Exposure time, handheld / tripod? Link to post Share on other sites More sharing options...
pico Posted March 17, 2015 Share #10 Posted March 17, 2015 [...] That is a Holy Cow example. Perfect. I doubt I could ever focus and expose in such perfection. WTF is that guy doing? Thanks for ruining my illusion! . Link to post Share on other sites More sharing options...
adan Posted March 19, 2015 Share #11 Posted March 19, 2015 pico - The finish of a Dragon Boat race (essentially a drag race between two long canoe-type paddled boats). To determine the winner in close races, each boat has a flag-puller who grabs a flag from a buoy at the finish line and tosses it in the air. First flag tossed = winner. The boats race in lanes, and each lane has its own flag buoy. The drummer beats out the paddling rhythm, as in old slave galleys. jan - hand-held. EXIF says 1/2000th @ f/6.7 @ ISO 320 As to focus, a 135 @ f/6.7 has pretty decent DoF at whatever this distance was - 450 ft/150 meters? Note how far behind and in front the ripples are still sharp. But I'll take credit for it, if you want. Link to post Share on other sites More sharing options...
